Leptospirosis is one of the most important contagious zoonosis diseases in Guilan province that caused by different serovars of Leptospira interrogans. The aim of the present study was conducted to determination of the prevalence rate of Leptospira pathogene serovars in Guilan province cows. Totally 450 serum samples were collected from Guilan cows and were tested by serology method
(MAT).The prevalence rate was 31.7% positive against to Leptospira infections. 81.7% of serum samples were positive to only one Leptospira serovars and 18.3% more than one spp. The percentage rate of Leptospira serovars were including: grippotyphosa (17.6 %), icterohaemprragia (49.3 %), pomona (1.4 %), serjohardjo (26.1 %), canicola (5.6 %). Percentage rate of MAT titers were 1:200 (0.7 %), 1:400 (21.1 %), 1:800 (30.3 %), 1:1600 (29.6 %), 1:3200 (14.8 %), 1:6400 (3.5%). Prevalence rate to leptospirosis was evaluated in different seasons and ages, it was much in 3-4 years (29%) and spring season (37.5%).
Seroepidemiological survey of Leptospirosis in rodents, education of rice field workers before agricultural seasons and monitoring of the Leptospira infection in Guilan province after educational programmes are recommended.
