 Serologic tests were performed in 1545 serum samples collected from pigs in 83 farms of the State of Rio Grande do Sul, Brazil, in the period of April, 1994 to April, 1995. Part of the farms had a history of reproductive disorders (31 herds, 654 samples), while the remaining sem derived from farms free of reproductive abnormalities (52 herds, 891 samples). Results of microscopic agglutination tests showed 121 (13.58%) positive reactors (titer equal or greater than 1:100) in the free herds. In the herds with history of reproductive disorders, 276 (42.9%) of the sera were positive. Positive titers for L. bratislava (57.2%) and L. icterohaemorrhagiae (13.76%) were more preválent in farms with reproductive problems. There was also cross reaction to these serovars.
