Abstract

SANTOS, Carolina de Sousa Américo Batista et al. Risk factors associated with Toxoplasma gondii seroprevalence in goats in the State of Paraíba, Brazil. Rev. Bras. Parasitol. Vet. [online]. 2012, vol.21, n.4, pp.399-404.  Epub Nov 27, 2012. ISSN 1984-2961.  http://dx.doi.org/10.1590/S1984-29612012005000002.

A cross-sectional study based on planned sampling was carried out to determine flock-level risk factors associated with Toxoplasma gondii antibody prevalence in dairy goat flocks in a semiarid region of northeastern Brazil. Serum samples from 975 adult dairy goats from 110 flocks were examined by indirect immonufluorescent antibody test (IFAT), using cut-off point at 1:64 dilution. From the 110 flocks, 77 presented at least one seropositive animal, corresponding to a prevalence of 70% (95% CI: 60.5-78.4%). Out of the 975 animals, 177 (18.1%; 95% CI = 15.8-20.7%) tested positive. The presence of toxic plants (OR = 5.11; P = 0.045) and the fact that goat breeding is not the main activity on the farm (OR = 3.34; P = 0.014) were identified as risk factors. The results of the present study showed evidence of the presence of T. gondii infection in dairy goats from a semiarid region of northeastern Brazil using planned sampling. Further studies are needed to elucidate the importance of the identified risk factors in the epidemiology of the infection.
