Abstract

Reproductive problems are the main clinical manifestations of leptospirosis in cows and it is often the only signs observed in the herd. Leptospira Interogans serovar hardjo is the most prevalent and important because it affects the reproductive performance of herds, but serological surveys in Brazil have shown mixed results regarding the occurrence of serovars in animal species. The serovar butembo, usually when found, is present in small proportion of positive results, however, our survey indicated an increase in the prevalence of this serovar in the samples received and processed from January 2005 to December 2008. Thus, the objective of this study was to report an increase in the detection of serological variant butembo in bovine serum from the state of Santa Catarina, in the samples analyzed by the Laboratory of leptospirosis (Lablepto) from Universidade Federal de Santa Maria (UFSM). Keywords: Leptospirosis, butembo, cattle, Santa Catarina State, Brazil.
