the prevalence of sarcosporidiosis in australian meat animals.	the prevalence of sarcocystis infectious in tasmanian sheep, cattle and pigs was assessed during february 1974. serological results indicated that over 90% of sheep and cattle were infected. macroscopic sarcocysts were found in 0.6% of lambs, 8.8% of 2- to 6-tooth (1 to 4 years old) sheep and 66% of full-mouth (4 years and older) sheep. the minimum prevalence in pigs, as determined by microscopic examination of muscle tissues, was 1.4% for animals less than 12 months old and 16.7% for animals ol ...	1975	812465
antibody to togaviruses in the northern territory and adjoining areas of australia.	antibody to flaviviruses murray valley encephalitis (mve) and kunjin and to alphaviruses ross river and sindbis were found in many aboriginal children and adults bled in central australia in 1974 after several cases of mve occurred there as part of a widespread epidemic. antibody was also detected in sera taken in the period 1968 to 1973, but in a much lower proportion, suggesting both that the 1974 epidemic had caused frequent sub-clinical infection and that infection had occurred in the arid c ...	1977	901314
enterocolitis due to yersinia enterocolitica in south australia.	from august 1976 to july 1977, all faecal specimens (3298) sent to the enteric department of the institute of medical and veterinary science, adelaide were selectively cultured for yersinia enterocolitica. yersinia enterocolitica was isolated from three patients with diarrhoea, one of whom acquired her infection overseas. these organisms were not isolated from faecal or lymph node material collected from a limited number of sheep and pigs found to have enteritis at the time of slaughter. enteric ...	1979	431980
legionnaires' disease in south australia. prevalence and diagnosis.	legionella pneumophila was successfully isolated from sputum, and from respiratory secretions obtained by tracheal aspiration, of two patients with legionnaires' disease by means of guinea pigs and charcoal yeast extract agar. direct culture of lung tissue from one of these patients gave a pure growth of l. pneumophila. in both cases, legionellas were isolated from specimens which were collected several days after treatment with erythromycin began. direct fluorescent antibody tests on these spec ...	1980	6993890
the kangaroo island strain of pig in biomedical research.	the feral pig from kangaroo island, south australia, has descended from british breeds released onto the island by early explorers approximately 180 years ago. it has developed into a smaller pig than the modern commercial equivalent, with distinctive and reproducible physical characteristics and a physiology which appears to bestow on it some advantages in terms of fitness and vigour. it has adapted easily to laboratory and intensive piggery conditions where it has reproduced satisfactorily. it ...	1981	7271607
