leptospira interrogans serovar hardjo is not a major cause of bovine abortion in victoria.the aim of this study was to determine whether evidence could be obtained of foetal infection with leptospira interrogans serovar hardjo in aborted foetuses collected from dairy farms. material from 197 abortions occurring over a wide area of victoria was collected over 3 years. none of 195 foetal kidney cultures or 7 cultures from membranes was positive for leptospiral organisms. immunogold silver staining for leptospires was performed on sections of kidneys, lungs or heart from 156 foetuses, w ...19892818362

genetic diversity among australian and new zealand isolates of leptospira interrogans serovar pomona.restriction endonuclease analysis of 16 australian and 4 new zealand isolates of leptospira interrogans serovar pomona showed that they could be divided into 3 genetic groups. most of the isolates closely resembled the serovar kennewicki reference strain, and they all differed from the reference strain of serovar pomona. based on these findings, it is suggested that vaccine manufacturers re-evaluate their choice of serovar pomona vaccine strain.19921632725
a serological survey of australian wildlife for antibodies to leptospires of the hebdomadis serogroup.a serological survey for antibodies to leptospira interrograns serovar hardjo was conducted on 574 serum samples from 10 native and 4 introduced wildlife species in south-eastern australia. the microscopic agglutination (ma) test was used, and titres to hardjo antigen were detected in 33.5% of 352 brushtailed possums (trichosurus vulpecula) sampled in several areas of victoria. prevalence of reactors ranged from 14 to 66% in 4 populations examined intensively. serovar balcanica was isolated from ...1979485984
cross-sectional study of canine leptospirosis in animal shelter populations in mainland australia.to measure the prevalence of canine leptospirosis in queensland and to detect infection, if present, in new south wales, victoria, south australia, western australia and the northern territory by measuring the serological titres of dogs held in animal shelters.200818673473
prevalence and geographic origin of pigs with serological evidence of infection with leptospira interrogans serovar pomona slaughtered in abattoirs in victoria, australia.a set of 10,440 sera was collected from pigs slaughtered at victorian abattoirs. these sera were subjected to the microscopic agglutination test for antibodies to leptospira interrogans serovar pomona. identification of the herd of origin was possible for 6511 pigs, and these were derived from 167 herds in victoria (84% of sera), from 32 herds in new south wales (8% of sera) and 29 herds in south australia (8% of sera). the overall prevalence of titres of 512 and above was 3.7%. this was higher ...19989791870
the prevalence of antibodies to members of leptospira interrogans in cattle.a total of 1,355 random samples taken from bovine serums submitted for brucellosis testing in victoria were submitted to the microscopic agglutination test for the presence of antibody to 12 serovars of leptospira interrogans. the most common reaction obtained was to serovar hardjo, although the percentage of reactors varied from 24.8% in the metropolitan area to 56.3% in north-eastern victoria (mean 40.6%). a total of 86.3% of farms from which 3 or more samples were taken had at least one react ...19807436939
