The incidence of leptospirosis among swine and cattle populations in the region of Stara Zagora was examined. The overall number of analyzed blood samples was 77282 (23875 porcine and 53047 bovine). The diagnostics was done retrospectively by detection of specific antibodies in animal blood via the reaction of microagglutination lysis using live cultures of Leptospira pomona, L. tarassovi and L. icterohaemorrhagica. In 1992-1999, leptospirosis was detected in 113 settlements and farms, 53 being pig farms and 60 - cattle farms. A tendency towards inctease of the incidence of leptospirosis in swine was noticed. Practical recommendations are proposed.
