RESUMO
Leptospirosis as a common zoonotic diseases has a worldwide distribution. To Investigate of seroprevalence leptospiral infection in slaughtered camels [Camelus dromedarius] province of Yazd, Iran. 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 1:100 were considered as positive ones. Sera with positive values were titrated against reacting antigens in serial dilutions from 1:100 to 1:400. 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. It seems that leptospiral with various serovars could be considered as a prevalent infection in camels of the central part of Iran
