FREQUENCY OF ANTI-LEPTOSPIRES AGGLUTININS IN SOWS FROM A SWINE HERD IN THE IBIÚNA MUNICIPALITY, STATE OF SÃO PAULO, BRAZIL

ABSTRACT A serologic survey was conducted among 164 sows from a single farrow-to-finish swine herd located in the Ibiúna municipality, state of São Paulo, Brasil, to determine the frequency of antileptospires agglutinins. For detection of anti-leptospires antibodies, the microscopic serumagglutination test (MAT) was carried out using live cultures of 22 pathogenic and two saprophytic Leptospira spp. serovars. The most frequent serovar was found crossing the results of frequency and titer of agglutinins, and sera presenting equal titers for two or more serovars were not considered for this analysis. Of the 164 sows, 27 (16.5%) were seropositive for at least one Leptospira spp. serovar. The most frequent serovar was Hardjo (Hardjobovis), with 13 (54.2%) reactant sera. Other reactant serovars and respective frequency were: Shermani (16.6%), Bratislava (12.5%), Autumnalis (12.5%) and Icterohaemorrhagiae (4.2%).
