2. We have identified one problem over where we are unable to act and this is the use of gonadotrophins in embryo transfer work. Some veterinary surgeons are quite legally using this exemption from the Medicines Act contained in Section 9(2) to prepare gonadotrophins from pituitary glands from various species, including cattle. These hormones are used to stimulate superovulation in donor cows.

I was quite prepared to believe in unofficial pituitary hormones, also in the 1970's, whether as described by Dr. Little, or in other circumstances, for animal use.

The fact that there were jars of pituitaries (or extract) around on shelves is attested by the still potent 1943 pituitaries, described in Stockell Hartree et al. (J/RF/17/291) which had come from the lab. at Mill Hill. Having taken the trouble to collect them, they were not lightly thrown out...

From: TSS Subject: How many NHS patients as having received blood from a donor who later developed vCJD were people with haemophilia Date: December 21, 2006 at 9:13 am PST

Health: vCJD Lord Morris of Manchester asked Her Majesty's Government:

How many NHS patients identified by the National Blood Service as having received blood from a donor who later developed vCJD were people with haemophilia. [HL750]

19 Dec 2006 : Column WA291

The Minister of State, Department of Health (Lord Warner): No patient with haemophilia or other bleeding disorders have been identified as having received blood from a blood donor who subsequently developed vCJD, nor have there been any reported cases of vCJD associated with receipt of plasma products.

However, all haemophilia patients who received plasma products between 1980 and 2001 sourced from UK donor plasma have been designated as "at risk of vCJD for public purposes". All plasma products are now sourced from non-UK plasma. The United Kingdom Haemophilia Centre Doctors' Organisation is collecting data that will provide an estimate of the number of haemophilia patients who have been exposed to plasma products which may be implicated with vCJD.

Lord Morris of Manchester asked Her Majesty's Government:

What is their response to the findings of Professor John Collinge in the December 2006 edition of the Lancet on the transmission by infected blood of variant CJD; and what action they are planning to take. [HL751]

Lord Warner: The Lancet article refers to the third known case of vCJD transmission via blood transfusion from a vCJD-infected donor. This case was originally notified to the department in January 2006 and announced by the Health Protection Agency in a press release on 9 February 2006, a copy of which has been placed in the Library.

There are 24 living patients in a group of people who had received blood components from donors subsequently known to have developed vCJD. They were all notified in 2005 or earlier, through their GPs, of their risk status and have been provided with information and support. The Health Protection Agency contacted the GPs earlier in the year to notify them of this third case and the agency has ensured that the GPs are fully informed and briefed about the subsequent Lancet publication.

The department has implemented a series of measures to reduce the risk of vCJD being transmitted through the blood supply. Shortly after vCJD was first identified in 1996, the possibility of human-to-human transmission through blood was considered, and the department implemented precautionary measures to reduce what was, at that time, a theoretical risk. These measures have been strengthened since evidence of transmission via blood began to emerge from animal studies, and following the first case of transfusion-associated transmission in humans, reported in December 2003. An important additional step, introduced in March 2004, was to exclude from blood donation those people who had themselves received a blood transfusion since January 1980. Other precautionary measures include:

from December 1997, blood components, plasma products or tissues obtained from any individual who later develops vCJD, were withdrawn/recalled;

19 Dec 2006 : Column WA292

in July 1998, it was announced that plasma for the manufacture of blood products, such as clotting factors, would be obtained from non-UK sources;from November 1999, white blood cells, which may carry a significant risk of transmitting vCJD, were removed from all blood used for transfusion;in August 2002, it was announced that fresh frozen plasma for treating babies and young children born on or after 1 January 1996 would be obtained from the USA; in July 2004, the exclusion criteria for blood donation were extended to include previously transfused platelet donors, and donors who were unsure if they had previously had a blood transfusion;in September 2004, the department announced further precautionary measures for patients who had received certain batches of plasma products;in July 2005, the use of USA-sourced fresh frozen plasma was extended to all children up to the age of 16;in July 2005, the department announced further precautionary measures for those patients who donated blood to three people who later developed vCJD. The department continues to keep all the evidence in relation to transmission of vCJD by blood under close review.

Thus for louping ill (unnecessary cites suppressed):

Paragraph 94 of Dr Maddocks supplementary statement (WS 467A)

(a)A sheep is another sheep’s worst enemy. I agree.

(b)Louping ill vaccine in sheep is associated with scrapie and growth hormone in humans. Someone at CVL would be very qualified to answer questions on the trial of louping ill vaccine which were carried out many years ago. Sheep tissue was used in the preparation. Unfortunately scrapie type symptoms and lesions appeared in the recipients of this vaccine. I am sure our medical colleagues could give more details of the human derived growth hormone, which was reported to have caused CJD symptoms in recipients of treatment with that product.

Vaccines and hormones are species specific prepared. This was not the case in this country. No cow pituitaries were used in the preparation of FSH products compared with the case of louping ill vaccine for scrapie.

WOW, WE NOW KNOW CWD AND SCRAPIE TRANSMITS TO PIGS BY ORAL ROUTE...terry


In the 1930's: 18,000 UK sheep were inoculated against louping ill, a brain inflammatory illness spread by ticks. Despite formalin-treatment of the inoculated agent, the procedure gave rise to 1,500 cases of scrapie. Louping is a Scottish word for fleeing or leaping, related to loping. In humans, louping ill is called Russian spring-summer encephalitis, a meningo-encephalitis with muscular tremors and spasms followed by varying degrees of paralysis.... [John Lanchester 2 Dec 96 New Yorker]

http://www.foodsafety.org/consumer/ht/ht294.htm


In what the story calls a grand historical irony, this landmark series of experiments was being confirmed at the same time in England as a result of an outbreak of scrapie in several hundred sheep that had been immunized against louping ill with a vaccine prepared from tissue from the brain, spinal cord, and spleen of sheep that were belatedly discovered to have been exposed to natural scrapie infection.[6.Gordon WS. Advances in veterinary research. Vet Rec 1946; 58: 516-520] The transmissible nature of the scrapie agent was thus established beyond any doubt. [P Brown, 1755 and All That: A Historical Primer of TSE.

We need to look at the full text of the article and its cites to see how they actually made the vaccine, whether they exported vaccine-infected sheep to Canada and the US, and what became of the vaccinated flocks. Perhaps there is still sample available, Moredun Institute is still around.

236. Mrs Alderman replied on 3 June 1988, listing products containing bovine insulin and noting there were two rabies vaccines listed but the species used in manufacture was not shown.[282] 237. On 6 June 1988 Mr Lawrence wrote to Sir Richard Southwood and enclosed some brief answers to the questions that had been tabled at the meeting on 19 May.[283] In relation to Q6, which asked OWhat is meat and other material from scrapie infected sheep used for - does it include pet food and material for biological products?¹ Part of the answer stated: ...

There has been one instance of inadvertant [sic] transmission of the scrapie agent to sheep through louping ill vaccine (Gordon, Bronlee and Wilson 1939). One of the three batches of vaccine made in 1935 at the Moredun Institute contained the scrapie agent resulting in 7% of the recipients of the 18, 000 doses in the batch developing scrapie. This vaccine was made from formalin-inactivated sheep brain, and brought to the attention of research workers that formalin, at a concentration of 0.35% for at least 3 months, which inactivated conventional viruses, did not totally inactivate the scrapie agent.


----------------------------


4. Questions we might want to have answered are: the highest risk would be from parenterals prepared from brain (eg rabies vaccine). Any species in which transmissible spongiform encephalopathies have been described would be suspect ("natural" infections in sheep, goats, cattle, deer, mink, but can be transmitted to hamster, mouse, guinea-pig etc). Are sterilisation processes adequate for the most resistant strain of scrapie agent or for CJD agent? Should companies be asked to include investigation for inclusion of scrapie agent (eg mouse innoculation [sic]) in at least some batches? If BSE behaves like scrapie, then we might expect other nervous tissue, spleen, lymph nodes and placenta to be contaminated. Infection has been described in other tissues too, eg gut wall, and we can not [sic] be sure blood is free. Do we know what bovine materials are used in which products, both as the active ingredient and in production? Bovine active ingredients in human products include insulin, vasopressin, bone, immune globulins, fibrin, dermal collagen, albumin. Bovine serum albumin and fetal calf serum must be used in preparation of very many products. For each of these products would any "BSE agent" be destroyed or eliminated in processing? If not, and the product is administered parenterally or topically into an open wound, might there be a risk? [For oral products, there would only be a trivially increased load on top of that taken in food in omnivores/carnivores including man. But for some herbivores, this might allow the agent to be introduced into yet another species].

One really has to wonder what went on in veterinary products produced during the peak BSE years. At this point, there are only 2 known incidents, both involving sheep brain vaccines.

I found a better source for needed references for iatrogenic scrapie in a nice review by Ray Bradley at http://www.iica.org.ar/Bse/6-%20Bradley.html. Disclosure has been meagre on the 1998 vaccine incident in Italy. Note 3 of the 5 references are totally off Medline and the other 2 fail to have abstracts or links, due to journal ineptness, burial in conference proceedings, and age of article.

If anyone has the first 3, I would appreciate a fax 542-484-0669 US.

IATROGENIC DISEASE IN ANIMALS


http://www.iica.org.ar/Bse/6-%20Bradley.html


Ray Bradley Private BSE Consultant Veterinary Laboratories Agency, United Kingdom

There have been two reported incidents of iatrogenic disease in animals, both involving scrapie. One was in Great Britain (Gordon, Brownlee and Wilson, 1939, Gordon 1946, 1959) the other in Italy (Capucchio et al, 1998, Agrimi et al, 1999). Both resulted from infection being introduced into vaccines, louping ill vaccine in Great Britain, Mycoplasma agalactiae vaccine in Italy. Each of these vaccines was prepared from tissues that included sheep brain. In both episodes it seems most likely that natural scrapie infection was present unknowingly in some brains used for the purpose. Once prepared and having passed all the conventional vaccine tests large numbers of sheep in Great Britain, and goats and some sheep in Italy were inoculated. After the necessary incubation period large numbers (> 1,000 in each case) of inoculated animals came down with scrapie. In the meantime some inoculated clinically healthy goats and sheep may have entered food and feed chains or have been used for other purposes. In the British outbreak there appears to have been no consequence for humans who may have consumed infected sheep. It is too early to say what may be the consequences in Italy but measures have been taken to reduce any risk there may have been. .........end

2.3.Iatrogenic exposure

Iatrogenic exposure of scrapie has probably occurred twice. The first report determined that the vehicle was a louping ill vaccine prepared from sheep tissues and this infected a large number of sheep sheep (Gordon, 1946, Greig, 1950). The second was more recent and in this case a vaccine against Mycoplasma agalactiae prepared from sheep tissues was incriminated (Agrimi et al 1999, Capucchio, 1998) but not all outbreaks could be linked to the use of the vaccine. In this episode goats were predominantly affected10.

5.3.3 The greatest risk, in theory, would be from parenteral injection of material derived from bovine brain or lymphoid tissue. Medicinal products for injection or surgical implantation which are prepared from bovine tissues, or which utilise bovine serum albumin or similar agents in their manufacture, might also be capable of transmitting infectious agents. All medicinal products are licensed under the Medicines Act by the Licensing Authority following guidance, for example from the Committee on Safety of Medicines (CSM), the Committee on Dental and Surgical Materials (CDSM) and their subcommittees. The Licensing Authority have been alerted to potential concern about BSE in medicinal products and will ensure that scrutiny of source materials and manufacturing processes now takes account of BSE agent.

40,000 human heart valves a year from BSE herds Sun, 3 Sep 2000. Unpublished Inquiry documents obtained by CJD activist Terry S. Singeltary Sr. of Bacliff, Texas

Opinion (webmaster): Below are some shocking documents. Here is a British company preparing 40,000 heart valves a year from bovine pericardium, primarily for export, and they are not required to source this material from BSE-free herds even in peak epidemic years. It is amazing to watch health "authorities" grovelling on their bellies to wring petty concessions from middle management at obscure little companies. The main worry is not the practise of using 800 potentially infected cows a week for human heart transplant material but that the press or recipients will get wind of it, hurting business.

BSE wasn't the problem, it was awkward queries from importing countries like the US. The cows are stunned using brain penetration -- can't do anything about the chunks of bovine brain blasted into the circulatory system, it's the norm. Can't use younger lower-risk animals either, patch would not be big enough. It is fascinating to see the British government worrying about, but doing nothing, with pigs with BSE 10 years ago.

While scrapie was long used as an excuse for continuing with human use of BSE-tainted material, little sheep material was used medically. Bovine transplants, vaccines, insulin doeses, etc. are far more dangerous than dietary material as injections, and are done on a very wide scale. So scrapie was never a valid analogy to BSE, as MAFF knew full well.

The British government deferred to the manufacturer's rep for an opinion on how contaminated pericardium might be, just as this appeared showing that this tissue is extremely dangerous:

Dear Mr Meldrum

BOVINE SPONGIFORM ENCEPHALOPATHY

You will recall that we have previously discussed the potential risks of BSE occurring in other countries as a result of the continuing export from the UK of meat and bone that may be contaminated by scrapie or possibly BSE.

I remain concerned that we are not being consistent in our attempts to contain the risks of BSE. Having banned the feeding of meat and bone meal to ruminamts in 1988, we should take steps to prevent these UK products being fed to ruminants in other countries. This could be achieved either through a ban on the export of meat and bone meal, or at least by the proper labelling of these products to make it absolutely clear they should not be fed to ruminants [or zoo animals, including rare and endangered primates -- webmaster]. Unless some such action is taken the difficult problems we have faced with BSE may well occur in other countries who import UK meat and bone meal. Surely it is short sighted for us to risk being seen in future as having been responsible for the introduction of BSE to the food chain in other countries.

Other US BSE risks: the imported products picture 24 Jul 00 Trade Statistics: UK to US Compiled by Terry S. Singeltary Sr of Bacliff, Texas

[Opinion (webmaster): The US has focused for years on tracing, containing, and eradicating live animal imports from the UK or other countries with acknowledged BSE like Belgium, including some 499 cattle and the Vermont sheep. This strategy does not acknowledge imports of rendered bovine products from England during the BSE period nor secondary products such as surgical catgut, which is to say surgical cowgut, or dairy cattle embryos, vaccines for veterinarian and human medicines. What has become of these?

Mr. Singeltary, who lost his mother to CJD of unexplained origin a few years back and went on to became a well-known TSE activist, has tracked down voluminous pertinent import data through correspondence with UK officials and searches of government web sites. Imports of such products are frequently cited by Europeans in rating BSE risks in the US and in shutting out US exports.

Many people's eyes glaze over when reviewing reams of sometimes older trade statistics. There is no proof that any of the imported products was contaminated with BSE nor if so, any evidence that any BSE product lead to infection in US livestock, surgical patients, or what not. Nonetheless, the data obtained by Mr. Singeltary establish that an appalling variety and tonnage of products that were imported by the US from the UK and othr BSE-affected countries during the peak of the BSE epidemic years.]

SURGICAL CATGUT SUTURES 2.1 At the first meeting of the Working Party on Bovine Spongiform Encephalopathy on 6 September 1989, detailed consideration was given to XXXXX Surgical Catgut. This arose from the Company's response to the Letter to Licence Holders, indicating that the bovine small intestine source material was derived from UK cattle, unlike 8 other licenced catgut sutures. In contrast XXXXX Surgical Catgut was stated to hold over 90% share of the market for catgut sutures, and to constitute approximately 83% of all sutures used in U.K. IMPORTS OF SUTURES FROM THE KNOWN BSE COUNTRY;

89/02.17/10.3

Q. Will government act on this?

A. Yes - thymus is not used in preparation of baby foods but it is contacting all manufacturers to seek their urgent views on use of kidneys and liver from ruminants. Will consider any necessary measures in the light of their response.

VETERINARY MEDICINES

Q. Can medicines spread BSE to other cattle/animals?

A. The report describes any risks as remote.

Q. How can risks be avoided?

A. In liaison with the DOH the Veterinary Products Committee is examining guidelines for the veterinary pharmaceutical industry which will be issued shortly.

Q. What will Guidelines say?

A. In essence they call for non-bovine sources to be used if possible, including synthetic material of biotechnological origin. Where this is not possible the industry should look for sources which are free of BSE and which are collected in a manner which avoids risk of contamination by the BSE agent.

89/02.17/10.4 MF580439/1 0588

A. Bovine source material is used in [garbled, cannot read...TSS] and some other medicines.

Q. How many medicines are involved?

A. Computer records show that about 300 of the 3,050 veterinary medicines licensed in the U.K. are manufactured directly from bovine source material. However, other medicines may be produced from bovine sources and a letter is going to all license holders so that a comprehensive list can be drawn up.

CATTLE BY-PRODUCTS AND BSE

I was interested to see the list of by-products sent to the HSE. Those of particular concern included:

* small intestines: sutures (I thought the source was ovine but you are checking this)

* spinal cord: pharmaceuticals

* thymus: pharmaceuticals

Are you able to give me more information on which UK manufacturers use these materials? Our proposed ban on bovine offal for human consumption would not affect these uses, I assume.

BOVINE SPONGIFORM ENCEPHALAPATHY MEETING HELD ON 21 AUGUST 1989 AT 2;15 IN ROOM 720 Miss M Duncan (Chairman) Mr W Burton Dr E Hoxey Mrs J Dhell Ms K Turner Dr S Whittle Mr N Weatherhead ... 5. The MCA had sent 2700 questionnaires out, 1,124 had made valid returns; of these 122 use animal material of some kind and there are 582 products involved. ... 6. The MCA/BSE working group will meet on 6th September. Their aim is to review responses from professional officers in MCA who have suggested seven categories of importance (with 1 being the most important} for medical products:

ID 2267/NRE/1 89/08.21/10.1

1. Products with Bovine brain/lymph tissue administered by injection.

2. Products with bovine tissue other than brain/lymph administered by inection.

3. Tissue implants/open wound dressing/surgical materials/dental and ophthlamic products with bovine ingredients.

4. Products with bovine ingredients administered topically.

5. Products with bovine ingredients administered orally.

6. Products with other animal/fish/insect/bird ingredients administered by injection/topically/oral routes.

7. Products with ingredients derived from animal material by chemical processing (eg stearic acid, gelatine, lanolin ext.

The BSE working group will decide which of these are important, and should be examined more closely, and which categories can be eliminated.

The responses by the companies were presented by Ms Turner and were categorised by MCA standards, the products that were discussed were all low volume usage products eg sutures, heart valves.

8. As the responses included some materials of human origin it was decided that more information should be sought about CJD. There had been 2 recent deaths reported associated with human growth hormone. These were being investigated.

9. Re-editing of the Paper on "Incubation of Scrapie-like Agents"

It was suggested that the document could be sent out to companies with the non-standard sterilization Document. The document could have severe implications on the companies whose products have a high risk factor as decided by the MCA working group....

11. The Need for a list of High Priority Implantables The commitee decided that no list is necessary as all implantables, including ones from a human source are of high priority. Concern was shown over Killingbeck who use human material but had not yet responded. The company will be chased for a response. Concern was shown over the fact that there may be other scrapie-like organisms in other animals and further enquiries should be made.

2334q/RD/4 89/08.21/10.7

BOVINE MATERIAL USED IN THE MANUFACTURE OF SURGICAL IMPLANTS AND BLOOD CONTACT MEDICAL DEVICES

Glutaraldehyde, formaldehyde, and ethylene oxide are used in the sterilization of these devices.

However, glutaraldehyde 4,10,12,19 formaldehyde 5,10,11,13,19 and ethylene oxide 19,23 are all reported to be ineffective methods for sterilization of material infected with the agents of CJD or scrapie.

Previous advice and research using the agents of CJD and scrapie, has concentrated on the decontamination of equipment; protection of health care workers from contaminated human material; human growth hormone; and dura mater. The methods developed may not be directly applicable or transferable to material of bovine origin for use in human implantation.

SO, looks like to me the most likely route of transmission of BSE to humans would be through inoculation i.e.

the most likely routes would be through contact with infective tissues through wounds or open lesions on the skin,

IF you look at all the successful transmission studies in the lab with TSE, inoculations was the most successful route.

Papers Presented to Congress

The papers presented to this year's Congress had as their general theme the progressive work of the profession during the war years. Their appeal was clearly demonstrated by the large and remarkably uniform attendance in the Grand Hall of the Royal Veterinary College throughout the series; between 200 and 250 members were present and they showed a keen interest in every paper, which was reflected in the expression of some disappointment that the time available for discussion did not permit of the participation of more than a small proportion of would-be contributors.

In this issue we publish (below) the first to be read and discussed, that by Dr. W. S. Gordon, M.R.C.V.S., F.R.S.E., "Advances in Veterinary Research." Next week's issue will contain the paper on "Some Recent Advances in Veterinary Medicine and Surgery in Large-Animal Practice" by Mr. T. Norman Gold, M.R.C.V.S. In succeeding numbers of the Record will be reproduced, also with reports of discussions, that by Mr. W. L. Weipers, M.R.C.V.S., D.V.S.M., on the same subject as relating to small-animal practice, and the papers by Mr. J. N. Ritchie, B.SC., M.R.C.V.S., D.V.S.M., and Mr. H.W. Steele-Bodger, M.R.C.V.S., on "War-time Achievements of the British Home Veterinary Services."

The first scientific paper of Congress was read by Dr. W. S. Gordon, M.R.C.V.S., F.R.S.E. on Monday, September 23rd, 1946, when Professor J. Basil Buxton, M.A., F.R.C.V.S, D.V.H., Prinicipal of the Royal Veterinary College, presided.

Louping-ill, Tick-borne Fever and Scrapie

In 1930 Pool, Browniee & Wilson recorded that louping-ill was a transmissible disease. Greig et al, (1931) showed that the infective agent was a filter-passing virus with neurotropic characters and Browniee & Wilson (1932) that the essential pathology was that of an encephalomyelitis. Gordon, Browniee, Wilson & MacLeod (1932) and MacLeod & Gordon (1932) confirmed and extended this work. It was shown that on louping-ill farms the virus was present in the blood of many sheep which did not show clinical symptoms indicating involvement of the central nervous system and that for the perpetuation and spread of the disease these subclinical cases were probably of greater importance that the frank clinical cases because, in Nature, the disease was spread by the tick, lxodes ricinus L. More recently Wilson (1945, 1946) has described the cultivation of the virus in a chick embryo medium, the pathogenic properties of this culture virus and the preparation of louping-ill antiserum.

Between 1931 and 1934 I carried out experiments which resulted in the development of an effective vaccine for the prevention of louping-ill.* This vaccine has been in general use since 1935 and in his annual report to the Animal Diseases Research Association this year, Dr. Greig stated that about 227,000 doses of vaccine had been issued from Moredun alone.

Dr. Gordon illustrated this portion of his paper by means of graphs and diagrams projected by the epidiascope.

This investigation, however, did not begin and end with the study of louping-ill; it had, by good fortune, a more romantic turn and less fortunately a final dramatic twist which led almost to catastrophe. After it had been established that a solid immunity to louping-ill could be induced in sheep, a group of immunized and a group of susceptible animals were placed together on the tick-infected pasture of a louping-ill farm. Each day all the animals were gathered and their temperatures were recorded. It was anticipated that febrile reactions with some fatalities would develop in the controls while the louping-ill immunes would remain normal. Contrary to expectation, however, every sheep, both immune and control, developed a febrile reaction. This unexpected result made necessary further investigation which showed that the febrile reaction in the louping-ill immunes was due to a hitherto undescribed infective agent, a Rickettsia-like organism which could be observed in the cytoplasm of the granular leucocytes, especially the neutrophil polymorphs (MacLeod (1932), Gordon, Browniee, Wilson & MacLeod. MacLeod & Gordon (1933). MacLeod (1936). MacLeod collected ticks over many widely separated parts of Scotland and all were found to harbour the infective agent of tick-borne fever, and it is probable that all sheep on tick-infested farms develop this disease, at least on the first occasion that they become infested with ticks. When the infection is passed in series through susceptible adult sheep it causes a sever, febrile reaction, dullness and loss of bodily condition but it rarely, if ever, proves fatal. It is clear, however, that it aggravates the harmful effects of a louping-ill infection and it is a serious additional complication to such infections as pyaemia and the anacrobic infections which beset lambs on the hill farms of Northern Britain.

Studying the epidemiology of louping-ill on hill farms it became obvious that the pyaemic condition of lambs described by M'Fadyean (1894) was very prevalent on tick infested farms Pyaemia is a crippling condition of lambs associated with tick-bite and is often confused with louping-ill. It is caused by infection with Staphylococcus aureus and affected animals may show abscess formation on the skin, in the joints, viscera, meninges and elsewhere in the body. It was thought that tick-borne fever might have been a predisposing factor in this disease and unsuccessful attempts were made by Taylor, Holman & Gordon (1941) to reproduce the condition by infecting lambs subcutaneously with the staphylococcus and concurrently producing infections with tickborne fever and louping-ill in the same lambs. Work on pyaemia was then continued by McDiarmid (1946a, 1946b, 1946c), who succeeded in reproducing a pyaemic disease in mice, guinea-pigs and lambs similar to the naturally occurring condition by intravenous inoculation of Staphylococcus aureus. He also found a bacteraemic form of the disease in which no gross pyaemic lesions were observed. The prevention or treatment of this condition presents a formidable problem. It is unlikely that staphylococcal ???oid will provide an effective immunity and even if penicillin proved to be a successful treatment, the difficulty of applying it in adequate and sustained dosage to young lambs on hill farms would be almost insurmountable.

From 1931 to 1934 field trials to test the immunizing value and harmlessness of the loup-ill vaccine were carried out on a gradually increasing scale. Many thousands of sheep were vaccinated and similar numbers, living under identical conditions were left as controls. The end result showed that an average mortability of about 9 percent in the controls was reduced to less than 1 percent in the vaccinated animals. While the efficiency of the vaccine was obvious after the second year of work, previous bitter experience had shown the wisdom of withholding a biological product from widespread use until it had been successfully produced in bulk, as opposed to small-scale experimental production and until it had been thoroughly tested for immunizing efficiency and freedom from harmful effects. It was thought that after four years testing this stage had been reached in 1935, and in the spring of that year the vaccine was issued for general use. It comprised a 10 percent saline suspension of brain, spinal cord and spleen tissues taken from sheep five days after infection with louping-ill virus by intracerebral inoculation. To this suspension 0-35 percent of formalin was added to inactivate the virus and its safety for use as a vaccine was checked by intracerbral inoculation of mice and sheep and by the inoculation of culture medium. Its protective power was proved by vaccination sheep and later subjecting them, along with controls, to a test dose of living virus.

Vaccine for issue had to be free from detectable, living virus and capable of protecting sheep against a test dose of virus applied subcutaneously. The 1935 vaccine conformed to these standards and was issued for inoculation in March as three separate batches labelled 1, 2, and 3. The tissues of 140 sheep were employed to make batch 1 of which 22,270 doses were used; 114 to make batch 2 of which 18,000 doses were used and 44 to make batch 3 of which 4,360 doses were used. All the sheep tissues incorporated in the vaccine were obtained from yearling sheep. During 1935 and 1936 the vaccine proved highly efficient in the prevention of loup-ill and no user observed an ill-effect in the inoculated animals. In September, 1937, two and a half years after vaccinating the sheep, two owners complained that scrapie, a disease which had not before been observed in the Blackface breed, was appearing in their stock of Blackface sheep and further that it was confined to animals vaccinated with louping-ill vaccine in 1935. At that stage it was difficult to conceive that the occurrence could be associated with the injection of the vaccine but in view of the implications, I visited most of the farms on which sheep had been vaccinated in 1935. It was at this point that the investigation reached its dramatic phase; I shall not forget the profound effect on my emotions when I visited these farms and was warmly welcomed because of the great benefits resulting from the application of louping-ill vaccine, wheras the chief purpose of my visit was to determine if scrapie was appearing in the inoculated sheep. The enquiry made the position clear. Scrapie was developing in the sheep vaccinated in 1935 and it was only in a few instances that the owner was associating the occurrence with louping-ill vaccination. The disease was affecting all breeds and it was confined to the animals vaccinated with batch 2. This was clearly demonstrated on a number of farms on which batch 1 had been used to inoculate the hoggs in 1935 and batch 2 to inoculate the ewes. None of the hoggs, which at this time were three- year-old ewes. At this time it was difficult to forecast whether all of the 18,000 sheep which had received batch 2 vaccine would develop scrapie. It was fortunate, however, that the majority of the sheep vaccinated with batch 2 were ewes and therfore all that were four years old and upwards at the time of vaccination had already been disposed of and there only remained the ewes which had been two to three years old at the time of vaccination, consequently no accurate assessment of the incidence of scrapie could be made. On a few farms, however, where vaccination was confined to hoggs, the incidence ranged from 1 percent, to 35 percent, with an average of about 5 percent. Since batch 2 vaccine had been incriminated as a probable source of scrapie infection, an attempt was made to trace the origin of the 112 sheep whose tissues had been included in the vaccine. It was found that they had been supplied by three owners and that all were of the Blackface or Greyface breed with the exception of eight which were Cheviot lambs born in 1935 from ewes which had been in contact with scrapie infection. Some of these contact ewes developed scrapie in 1936-37 and three surviving fellow lambs to the eight included in the batch 2 vaccine of 1935 developed scrapie, one in September, 1936, one in February, 1937, and one in November, 1937. There was, therefore, strong presumptive evidence that the eight Cheviot lambs included in the vaccine although apparently healthy were, in fact, in the incubative stage of a scrapie infection and that in their tissues there was an infective agent which had contaminated the batch 2 vaccine, rendering it liable to set up scrapie. If that assumption was correct then the evidence indicated that:-

(1) the infective agent of scrapie was present in the brain, spinal cord and or spleen of infected sheep: (2) it could withstand a concentration of formalin of 0-35 percent, which inactivated the virus of louping-ill: (3) it could be transmitted by subcutaneous inoculation; (4) it had an incubative period of two years and longer.

Two Frenchmen, Cuille & Chelle (1939) as the result of experiments commenced in 1932, reported the successful infection of sheep by inoculation of emulsions of spinal cord or brain material by the intracerebral, epidural, intraocular and subcutaneous routes The incubation period varied according to the route employed, being one year intracerebrally, 15 months intraocularly and 20 months subcutaneously. They failed to infect rabbits but succeeded in infecting goats. Another important part of their work showed that the infective agent could pass through a chamberland 1.3 filter, thus demonstrating that the infective agent was a filtrable virus. It was a curious coincidence that while they were doing their transmission experiments their work was being confirmed by the unforeseeable infectivity of a formalinized tissue vaccine.

As a result of this experience a large-scale transmission experiment involving the ue of 788 sheep was commenced in 1938 on a farm specially taken for the purpose by the Animal Diseases Research Association with funds provided by the Agricultural Research Council. The experiment was designed to determine the nature of the infective agent and the pathogenesis of the disease. It is only possible here to give a summary of the result which showed that (1) saline suspensions of brain and spinal cord tissue of sheep affected with scrapie were infective to normal sheep when inoculated intracerebrally or subcutaneously; (2) the incubation period after intracerebral inoculation was seven months and upwards and only 60 percent of the inoculated sheep developed scrapie during a period of four and a half years; (3) the incubation period after subcutaneous inoculation was 15 months and upwards and only about 30 percent of the inoculated sheep developed the disease during the four and a half years: (4) the infective agent was of small size and probably a filtrable virus.

The prolonged incubative period of the disease and the remarkable resistance of the causal agent to formalin are features of distinct interest. It still remains to determine if a biological test can be devised to detect infected animals so that they can be killed for food before they develop clinical symptoms and to explore the possibilities of producing an immunity to the disease.
