BACKGROUND:Leptospirosis is one of the bacterial zoonotic diseases among human and animals which determines by fever, jaundice and haemoglobinuria. Disease is common in north and southwest of Iran where buffaloes breeding widely called as Khozestan and Azarbyjan buffaloes. OBJECTIVES:Determination of the percentage of seropositive to leptospira infection in buffaloes. Age and gender relationships in leptospirosis. 3- Determination of serum titer and predominant leptospira antigens in Urmia buffaloes. METHODS:130 blood samples were collected in Urmia abattoir in 2011. Sera were separated and serological reaction to leptospira spp was assessed by microscopic agglutination test using live antigens representing leptospira interrogans serogroups: pomona, grippotyphosa, canicola, hardjo, icterrohaemoragia, and ballum. Overall, 25.4% including 26.9% males and 23.8% females with titer of 1:100 had positive reaction to one of the leptospira serovars. Among positive serovars the greatest was pomona (16.2%) and the lowest was icterohaemorrhagiae (1.52%). The most prevalent titer of leptospira was 1:100 included 20% (26 samples) and the highest was 1:200 included 10% (13 samples) of buffaloes. The age distribution in seropositive buffaloes with <1.5 year was the lowest (1.5%) and 3 to 4 years old was the highest (16%). Statistical results also showed the seropositive prevalence to leptospirosis among males and females were not significantly different. CONCLUSIONS: The seropositive to leptospira in Urmia buffaloes must be considered as an important disease and special attention is necessary due to the probable transmission of disease to other buffaloes and human. Thus, in the lack of vaccination programs for animals, the administration of hygienic methods, rodenticides and preventive procedures must be applied by farmers and veterinary organization.
