In this study we tested 550 sera blood samples in order to investigate seroprevalence of leptospiral infection in cattle managed in coastline area from Shkodër to Vlora in Albania. The sera samples were tested by means of the microagglutination test (MAT). Sera were stored at -20°C until use. They were initially screened at serum dilution of 1:100 against 9 strains of pathogenic serovars of Leptospira: icterohaemorrhagiae, canicola, copenhageni, pomona, hardjo, bratislava, tarassovi, grippotyphosa and ballum. The samples were judged as positive if ≥ 50% of agglutination of leptospira in a dilution test serum of ≥ l:100 were observed. Sera with positive results were titrated against reacting antigens in serial two-fold dilutions from l:100 to 1:3200. Antibodies against one or more serovars were detected in 65 (11.9%) sera at dilution ≥1:100. Antibodies against more than one serovar were found in 5 (0.9%) positive sera. Among the positive sera, antibodies were most frequent to serovar Icterohaemorrhagiae 36.9%, Hardjo 30.8%, Grippotyphosa 16.9%, Pomona 9.2%, Copenhageni 3.1%, Bratislava 3.1%. The results of this survey indicate that leptospiral infection is common in dairy cattle.
