Abstract

BACKGROUND: Leptospirosis as a common zoonotic diseases has a worldwide distribution. OBJECTIVES: To Investigate of seroprevalence leptospiral infection in slaughtered camels (Camelus dromedarius) province of Yazd, Iran. METHODS: Blood samples were collected from 128 camels. Sera were initially screened at serum dilution of 1:100 against six live antigens of (Leptospira interrogans serovars pomona, canicola, hardjo, ballum, icterohaemorrhagiae, grippotyphosa) using microscopic agglutination test. The values �50 in a dilution l:100 were considered as positive ones. Sera with positive values were titrated against reacting antigens in serial dilutions from l:100 to 1:400. RESULTS: Antibodies against one or more serovars were shown in 30 (32.4) sera at dilution �1:100. Among the positive sera, pomona (57.9) canicola (23.7), hardjo (10.5), grippotyphosa (5.3) and icterohaemorrhagiae (2.6) were the most frequent serovars,respectively. Furthermore antibodies against more than one serovar were found in 8 (26.6) of positive sera. CONCLUSIONS: It seems that leptospiral with various serovars could be considered as a prevalent infection in camels of the central part of Iran.
