I went to the Royal Veterinary College in 1962. I qualified in December 1967 in the heat of Foot and Mouth Disease.

Between 1968 and 1970 I was the beneficiary of a Pig Industry Development Authority (PIDA) studentship in the Dept of Pathology, initially being trained by Klaus Jericho before he returned to Canada both of us under the auspices of the late Professor ‘Ernie’ Cotchin. This gave me a good training in large animal medicine, animal husbandry, routine diagnostic pathology, and in pig research. These PIDA awards were the best thing that ever happened in pig research.

These newly acquired skills were honed in Animal Health at the RVC with Professor Jet Jones whose MSc course was a benefit to very many veterinarians from all over the world. It was also an opportunity to run the college pig unit and an advisory group in Hertfordshire and Bedfordshire during the period from 1970-1975. Three years in practice followed but in 1978 I returned to the RVC to teach farm animal anatomy, histology and embryology with legends of veterinary anatomy Ray Ashdown and the late Peter Goody. This period led to co-authorship of three illustrated atlases of horse, ruminant and canine anatomy. By this time the late Jack Done, head of Pathology at the Central Veterinary Laboratory (CVL) had decided that I had learnt enough of the background subjects essential for a farm animal investigator and pathologist to be invited to join the Pathology Department (1983).

Over the next twenty years pathological investigation produced a large number of research topics and papers but by 2002 CVL was into data collection. The main thrust of veterinary investigation was in the Regional Diagnostic Laboratories and so it was a big northern adventure to take the post of SVIO at the VLA-Thirsk Regional Laboratory. In some ways this was like coming home as Thirsk RL together with Bury St Edmonds are the main centres of the VLA pig activities. I have been extremely fortunate with most of my colleagues particularly in The Pig Veterinary Society. This has enabled me to write nearly 300 communications of various sorts including contributions to 5 textbooks. I now teach ‘piggy bits’ at 2 Veterinary Schools.

Swine influenza: epidemiology and emergence of new viruses

Stan Done S. Done
The first swine influenza viruses were all H1N1 and were for about 60 years in North America. In the middle 1980’s, there appeared in European pigs H3N2 viruses that were derived originally from humans and had adapted to pigs and were therefore known as human-like H3N2 viruses. These viruses have since appeared in other parts of the world most notably as H3N2 in the USA in 1998. These viruses however contained bits of human, avian and swine viruses and were therefore called triple re-assortants.

North-American human influenza

Stan Done S. Done
It is produced by a virus with genetic material from porcine, human and avian viruses which has shown the ability unusually for such a virus to transmit from human to human. The virus appears to have 2 of 8 gene segments that derive from eurasian swine viruses. The NA and matrix genes of the new virus have not been seen in humans or pigs before.

North American H1N1 influenza update

Stan Done S. Done
The usual pig viruses are H1N1, H3N2 and H1N2. The original H1N1 pig viruses have been largely replaced by poultry viruses in pigs. The H3N2 viruses were from humans originally. The H1N2 viruses are re-assortants from human viruses (H and N genes) and poultry viruses.

Differential diagnosis of nervous diseases in the pig

Stan Done S. Done
In the diagnosis of nervous conditions it is difficult to establish initially, whether the problems lie in the bones, joints, muscles, or tendons or nerves. We should rule out anatomical or pathological problems in the former four systems before we assume we are dealing with nervous system problems.

Summary of swine influenza (1/2)

Stan Done S. Done
Normally, in pigs influenza is an acute respiratory infection with pyrexia, lethargy, prostration, reluctance to eat and drink. Indoor housed pigs are usually affected simultaneously, with recovery within 1-2 weeks. No adverse effects occur unless there is secondary infection.

Foot and Mouth lessons for Europe

Stan Done S. Done

It is essential that veterinarians update their knowledge and educate livestock farmers and employees to familiarize themselves with exotic diseases, such as foot-and-mouth disease or ASF, since their detection requires knowledge of them.

Foot and Mouth Disease 2001

Stan Done S. Done

The appearance of Foot and Mouth Disease Type 0 (Asian types) in the United Kingdom shortly after the occurrence of Classical Swine Fever has generated a very deep crisis in United Kingdom livestock industry. The occurrence of the two so soon after one another, and both supposedly originating from the same part of the world suggests that there have been changes in the patterns of food importation into the UK that have allowed these strains to enter.
