Abstract: A serological study for several serovars of Leptospira sp. was undertaken on a randomly selected population of beef cattle in 22 municipalities of Nuevo Leon, Mexico. Blood samples were collected from 1400 animals and sera were tested for antibodies against 12 serovars of Leptospira sp. (bratislava, canicola, gryppotyphosa, hardjo, hebdomadis, icterohaemohrragiae, panama, pomona, pyrogenes, shermani, tarassovi, wolffi) using the microscopic agglutination test. Antibodies against one or more serovars were detected in 646 sera (46%) of the 1383 samples tested. The most prevalent serovars detected were hardjo (19.8%), wolffi (18.6%) and tarassovi (6.5%).
