Seroprevalence of bovine leptospiral antibodies by microscopic agglutination test in Southeast of Iran

摘要

cqvip:Objective:To evaluate serological findings of bovine leplospirosis which is a zoonotic disease with worldwide distribution caused by Leptospira interrogans.Methods:One hundred and sixty seven sera were collected from 9 commercial dairy herds in jiroft suburbs,from July to October 2011.Microscopic agglutination test(MAT) was used to evaluates serological findings of bovine leplospirosis in Jiroft suburb dairy farms,Kerman province,Iran.Results:Antibodies were found by MAT at least against one serovar of Leptospira interrogans in29 samples(17.36%) among 167 sera at a dilution 1:100 or higher,and Leptospira pomona was the most prevalent serovar.Positive tilers against more than one serovar were detected in 6 sera of the positive samples.Conclusion:This study is the first report of leplospirosis in Southeast Iran and showed that Leptospira pomona was the most and Leptospira icterohaemorrhagiae the least prevalent serovars in Southeast Iran.
