METHODS: Serum samples of native (n=139) and crossbreed cows (n=261) were examined using ELISA method values were analyzed by description analysis. RESULTS: The frequency of prevalence for N.caninum antibodies was shown as much as 20 % . Furthermore, the most and the least frequency rates were shown in cattle over 4 years old (32.33%) and less than 2 years old (7.32%) , respectively (p<0.05) . Meanwhile, 64% of cows which had abortic chain were seropositive (p<0.05).
