A microscopic seroagglutination test, including 12 serovars of Leptospira interrogans as antigens was used. Samples with titres > 100 were considered positive. Two hundred and twenty-one (47.63%) of the samples were positive to one or more serovars. The prevalence of the serovars was hardjo (21.98%), bratislava (15.73%), castellonis (11.64%), tarassovi (10.56%), pyrogenes (1.72%), icterohaemorrhagiae (1.08%), pomona (0.86%), wolffi (0.86%), grippotyphosa (0.86%), djasiman (0.43%), canicola (0.21%), and copenhageni (0.21%).© ARC-Onderstepoort and Faculty of Veterinary Science, University of Pretoria (original). © University of Pretoria.
