ABSTRACT
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 164 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.(AU)
RESUMO
Foi conduzido um estudo transversal baseado em amostragem planejada com o objetivo de determinar fatores de risco associados com a prevalência de anticorpos contra Toxoplasma gondii, em rebanhos de caprinos leiteiros, em uma região semiárida do Nordeste do Brasil. Amostras de soro de 975 caprinos leiteiros adultos, procedentes de 110 propriedades, foram examinadas pela reação de imunofluorescência indireta (RIFI), utilizando-se como ponto de corte a diluição 164. Das 110 propriedades, 77 apresentaram pelo menos um animal soropositivo, correspondendo a uma prevalência de 70% (IC 95% 60,5-78,4%). Dos 975 animais, 177 (18,1%; IC 95% = 15,8-20,7%) foram positivos. Apesar da presença de plantas tóxicas (OR = 5,11; P = 0,045) e da caprinocultura não ser a principal atividade na propriedade (OR = 3,34; P = 0,014), foram identificados como fatores de risco. Os resultados do presente estudo mostraram uma evidência da presença da infecção por T. gondii, em caprinos leiteiros, em uma região semiárida do Nordeste do Brasil, utilizando-se uma amostragem planejada. Há necessidade de condução de estudos posteriores para elucidar a importância epidemiológica dos fatores de risco identificados.(AU)
