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
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
