The incidence of bovine TUBERCULOSIS in the Alice Springs area was negligible but in 6, 472 cattle slaughtered at Darwin 3.37% were infected. Up to 9% of infected cattle were found in some mobs sent into Queensland. Of 1, 373 pigs killed at Darwin 8% were infected with TB. Some of the cases were in ...

Bovine VIBRIOSIS was studied to assess the value of vaccination and to record the events leading to infertility. V. fetus cultures were introduced into the vagina a year before heifers came to first service to determine whether immunity will develop from such an exposure. A killed culture was used...

An experimental herd remained free from Str. agalactiae mastitis for a further year following elimination of the organism by treatment with penicillin, closing of the herd and maintenance of good shed hygiene. After exposure to natural infection with BRUCELLOSIS no evidence of infection was found...

A number of outbreaks of LEPTOSPIROSIS (ICTEROHAEMOGLOBINURIA) or "REDWATER OF CALVES" occurred. Adult cattle were also affected and had fever followed by anaemia and jaundice. In some cows there was permanent udder damage and depression of milk yield was always serious. Laboratory examination was...

An outbreak of SALMONELLOSIS occurred in bulls which had travelled some distance by rail and road. There were a number of deaths and the following strains were isolated: S. typhimurium, S. muenchen, S. anatum, and S. london. The cattle had acute cellulitis followed by sloughing of lesions which...

Sheep vaccinated against CASEOUS LYMPHADENITIS challenged by i/d injection yielded inconclusive results owing to loss of virulence. Results from field trials did not support previous indications that either vaccination or the use of a "clean" rested pasture for newly-shorn sheep had been useful in...

STAFF.-There has been, and is, considerable difficulty in securing the services of a sufficient number of veterinarians for appointment, but it is anticipated that in a year or two a larger number of men will be forthcoming from the veterinary school of Sydney University. At present the Veterinary...

Studies on MASTITIS confirmed reports that a closed herd will remain free after Sir. agalactiae has been eliminated. This is not so with staphylococcal infections which treatment with antibiotics usually failed to remove from infected udders. Work on calf hood vaccination with Br. abortus Strain 19 ...

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,...

Neither aureomycin nor furacin (5-nitro-2 furaldehyde semicarbazone) was effective against staphylococcal MASTITIS. The potassium salt of penicillin G was irritant and caused fibrin clots. Vaccination of sheep against CASEOUS LYMPHADENITIS reduced the incidence to about half that in controls. Sheep ...
