ABSTRACT
This study was conducted on 130 ewes in Khoy area in the north of Iran in order to seroprevalence of leptospiral infection. Sera were initially screened at dilution of 1:100 against 6 live serovars of Leptospira interrogans: Pomona, Canicola, Hardjo, Ballom, Icterohaemorrhagiae and Grippotyphosa using the microscopic agglutination test (MAT). The prevalence of leptospiral infection was 28.46% in ewes. 59.45% of infected ewes were in the moist stable and 40.54% were in the non moist stable and there was significant difference between prevalence them (P<0.05). There was no significant relationship between aging of the ewes. The highest number of reactors in ewes (56.25%) was due to serovar Canicola, followed in descending order by Grippothyphosa (20.83%), pomona (12.50%), Hardjo (6.25%) and Icterohaemorrhagiae (4.16%). The majority of titer levels were between 100 and 200 for all the serovars. These results confirm that the majority of leptospiral infections are asymptomatic and the presence of antibodies in the absence of infection indicates exposure to the organism in these animals.
