Title

SEROPREVALENCE OF LEPTOSPIRAL INFECTION IN DAIRY HERDS IN TABRIZ - IRAN

Pages

  67-77

Abstract

 Leptospirosis is a world-wide zoonotic infection occurring in animals and human. Rodents and wildlife are a major source of infection. Clinical signs in cattle include fever, heamoglubinuria, jaundice, abortion, mastitis, reduced in milk production, reproductive failure and death. In this survey, the SEROPREVALENCE of LEPTOSPIRAl infection in DAIRY herds and the relationship between SEROPREVALENCE and animal and environmental factors in TABRIZ were investigated. 229 serum samples randomly collected from herds since December 2002 to November 2003. Sera were tested by MAT using live LEPTOSPIRA interrogans serovars: Hardjo, pomona, icterohaemorrhagiae, grippotyphosa, canicola and ballum. Twenty four percent of sera were seropositive against one or more of studied serovars. Pomona and grippotyphosa were detected as the most-prevalent serovars with 34.2% and 32.9% respectively. All of sera were seronegative for hardjo. The Chi-square method used for seasonal tend of seroconvertion against this serovars. The risk of SEROPREVALENCE against LEPTOSPIRA was significantly higher in winter and autumn. In farms, where rodents had been observed, and or moisture were high, the SEROPREVALENCE was higher than others. Also most seropositive cases were observed in 3-4 years old cows. According to presence of serological infection in DAIRY herds, use of prevention factors were suggested.
