The municipality of Mossoró, RN, Northeastern Brazil, is featured on goat rearing. Toxoplasmosis is a zoonosis which is more pathogenic for goats when compared with other animals for slaughter. In this species, the protozoan is often responsible for reproductive problems and economic losses. In order to identify the seroprevalence and risk factors of toxoplasmosis in goats of farms in this municipality, serum samples from 338 animals (320 females and 18 males) of 15 production units were tested by enzyme immunoassay (ELISA). Of the 15 farms, 14 had animals positive for Toxoplasma gondii, and in these the total number of seropositive animals were 125 (123 females and 2 males), yielding a prevalence of 37.0%. There was a significant relationship (p<0.05) between prevalence and sex, and between the prevalence and breed of animals. The most important risk factors associated with T. gondii infection were: water supply with odds ratio (OR=2.635), containers for water animals located outside the premises of property (OR=3.121) and the exploitation of dairy type (OR=2.546). For the analysis of the avidity ELISA, was found females of reproductive age in the acute phase of infection. |
