This research was aimed at reporting an outbreak of infertility in milking cows at a farm in the state of Santa Catarina, Brazil, that could be caused by Leptospira butembo. Eleven serovars of Leptospira were used for testing 13 cow serum samples against leptospirosis by using the microscopic agglutination test (MAT). All serum samples of the animals reacted with L. butembo serovar with titles between 100 and 800. After treatment with streptomycin sulfate, 92% of the animals returned to reproductive life. These results suggest that L. butembo may have been responsible for the bovines reproductive problems.
