Abstract

A sero-epidemiological survey was conducted to determine the prevalence and distribution of Brucella ovis infection in ovines from the northern region of Mato Grosso State, Brazil. The risk factors for the infection were also verified. 337 blood samples from rams and sheep of reproductive age from 11 sheep herds of four municipalities at Alto Teles Pires and Sinop mesorregion were investigated. All sera were examined by of immunodifusion in agar gel. From the total of examined herds, 72.7% (n=8) of the farms presented at least one seropositive animal for Brucella ovis. The mean prevalence of seropositive animals was 13.9% (99% CI). The seropositivity was lower in extensive productions and in herds where cleanliness was frequently observed (p<0.05). We conclude that the sheep industry in northern Mato Grosso State is still not a main economic activity, leading to low productivity and predisposition to the occurrence of ovine brucellosis and other diseases due to poor techniques applied in breeding
