Bovine enzootic haematuria was diagnosed in Queensland in coastal areas in association with bracken fern (Pteridium esculentum) on 3 properties or with mulga fern or rock fern (Cheilanthes sieberi) on 4 properties, and in inland areas in association with C. sieberi on 3 properties. In the absence of bracken fern, long-term ingestion of C. sieberi is suggested as a cause of bovine enzootic haematuria. Haemangiomas, haemangiosarcomas, transitional cell carcinomas, papillomas, fibromas and an adenoma were detected in the urinary bladders of 19 affected cattle and were accompanied by chronic cystitis. 相似文献

Acute fatal infection with Pseudomonas pseudomallei caused pneumonia, placentitis and endometritis in a pregnant cow. Pneumonia was also present in the foetal lung. Mononuclear cell response with extensive karyorrhexis occurred in maternal and foetal lung and the same cellular pathology, but with diffuse distribution, was responsible for plaques on the endometrium. A more chronic disease with encapsulated caseous lesions in the lung, together with arthritis, occurred in a bull on the same property. Nutritional and physical stress caused by a flood were thought to be predisposing factors. An unusually wet summer with prolonged flooding apparently provided suitable environmental conditions for saprophytic growth of Ps. pseudomallei in an area far south of the region in which infection of animals with this organism commonly occur. 相似文献

Over a 3-year period, 1178 faecal samples were cultured from 462 horses admitted to the equine clinic of the University of Queensland; 185 samples were positive for salmonella yielding 213 isolations consisting of 21 serotypes. S. anatum was the predominant serotype isolated (54%) followed by S. ohio (11.27%) and S. typhimurium (9.4%). One hundred and ten horses (23.81%) were positive on one or more occasion, and 42 (9.09%) on more than one occasion.
S. anatum was the most common serotype isolated (71.43%) from the main drains in the stable block (33.57% positive samples).
The prevalence of salmonella excretors among a large non-clinic population of horses in south east Queensland was 1.65%.
Acute salmonellosis did not occur in the hospitalised animals. However, salmonellas were incriminated in 6 cases of chronic diarrhoea, which all yielded S. anatum , although the most severe involved both S. anatum and S. typhimurium , and these serotypes were isolated from multiple locations at the subsequent autopsy of 3 cases. 相似文献

Natural infection of calves with Anaplasma marginale was studied in two endemic areas of tropical north Queensland. Infection, assessed by a micro-complement fixation test, occurred throughout the year but was most frequent just after the summer wet season. Infection was clinically inapparent. Calves vaccinated with A. centrale did not show improved growth rate when compared with non-vaccinated calves. The complement fixation test was shown to be most effective in the detection of recent infections. 相似文献
