Sažetak
From 1981 to 1991, sera of 42 European brown bears (Ursus arctos) from three areas in Croatia were tested for antibodies against 12 Leptospira interrogans serovars: grippotyphosa, sejroe, australis, pomona, canicola, icterohaemorrhagiae, tarassovi, saxkoebing, ballum, bataviae, poi and hardjo. Diagnostic levels of antibody were found in 17 of 42 (40%) sera. Evidence of exposure to at least one of the serovars was found in: (1) seven of 14 (50%) free-ranging bears from the Lika region, (2) four of 12 (33%) free-ranging bears from the Gorski kotar region, (3) zero of six (0%) orphaned cubs from the Gorski kotar region, and (4) six of 10 (60%) captive bears from the Zagreb Zoo. Evaluation of the magnitude of antibody titers implicated the following serovars: (1) australis in five bears, (2) sejroe in two bears, (3) canicola in one bear, and (4) icterohemorrhagiae in one bear. There was a strong correlation between serovars implicated by this survey and serovars previously isolated from small mammals in Croatia.
