SWINE FEVER: a trial of the Chinese strain of lapinized virus showed that it was safe to use as a vaccine in Belgium. Antibodies to porcine picorna-virus (SMEDI virus) were found in at least 59 of 194 serum samples; their incidence did not seem to be related to abortion and sterility. A comparison...

The laboratory has operated in the Republic of Panama for 38 years, and has a special interest in bio-medical ecology. Investigations are reported into arboviruses, leishmaniasis, trypanosomiasis in man and wild animals; malaria and other parasitic diseases; certain bacterial diseases; entomology;...

Foot and mouth disease virus. Type A. was rendered avirulent by 28 passages in day old chicks or 12 in embryonated eggs. These strains, were non-pathogenic, had good antigenicity and did not spread by contact. In field trials with the chick embryo strain immunity lasted at least eight months....

Mycoplasma sp. was recovered from a herd of cows with high incidence of MASTITIS which did not respond to penicillin. In another herd, a slow growing organism similar to Streptococcus thermophilus was recovered. A survey was begun to deter-mine the point of entry of Salmonella spp. into meat meal....

The A. R. C. Field Station at Compton, the first research centre to be established under the direct control of the Council, was set up in 1938 primarily for the purpose of intensifying research into diseases of animals.
In developing the Station the policy has been to breed and rear a disease-free...

II. A pasteurella was isolated from the milk of cows in one herd for over 12 months. Affected cows showed acute MASTITIS with ropy milk and there were severe systemic effects. Lancefield Group 0 streptococci were recovered from a herd in which 20 of 25 cows showed systemic effects and painful...

An outbreak of disease among guineapigs was due to Pasteurella pseudotuberculosis, and was eradicated by the use of a slide agglutination test.
OVINE BRUCELLOSIS can be transmitted to clean rams grazing with infected rams, but not by grazing pastures previously grazed by the infected animals. The...

II. Many cases of TUBERCULOSIS continue to be reported in cattle slaughtered at Darwin and Wyndham but little can be done to control TB. until staff and facilities are increased. An outbreak of disease in a herd travelling by rail closely resembled PASTEURELLOSIS (PULMONARY HAEMORRHAGIC...

Green zone (viridans) streptococci have been isolated from over 60 cows suspected of being infertile, although such strains are also found in the normal bovine genital tract. Four sheep in a group of 50 revealed intervertebral abscesses due to Corynebacterium ovis. A Pasteurella-like organism was...

Studies on MASTITIS were limited to testing antibiotics against staphylococcal infections. Neither intensified aureomycin treatment, pro-caine penicillin plus 5-amino acridine, furacin, terramycin nor neomycin was satisfactory.
Methods of control practised against CASEOUS LYMPHADENITIS in sheep,...
