Leptospirosis is one of the most common diseases between animal and human around the world. Regarding to the death report of a farmer in Gorgan because of leptospirosis and abnormal mortalities in forest mice in Aliabad-e-Katul,it had seemed to be necessary to investigate Leptospirosis Golestan province. Therefore, this study was considered the prevalence of Leptospira interrogans in serum samples of Golestan province cattle. Blood samples were collected from 505 cattle with different ages at Golestan province and were examined by microagglutination method. The incidence of leptospirosis was investigated at different ages, sex, and seasons using chi-square method and SPSS. The results showed that from the total samples, 137 (%27.22) samples had positive serologic response, of which 108 (%78.84), 25 (%18.25), and 4 (%2.91) of samples had one, two and three positive reaction serotype, respectively. Among samples with positive serologic response, %32.75, %26.31, %22.22, %9.15, %5.27 and %3.50 showed a positive reaction on icterohaemorrajiae, serjerohardjo, automnalis, gripotyphosa, Pomona and canicola, respectively. The highest frequency (%30.99) was observed in the 1: 800 Titration. The highest frequency was observed at age of 2 to 3 years old (%52.63), female (%27.48) and in summer (%37.93), which was not statistically significant (P> 0.05).Leptospirosis infection is actively present at the province. Comparison of the dominant serotype indicated a change in the pathogenic variant from Gripofoza in 2007 to ectoharmasia at the time of the present study.
