Soroprevalência e fatores associados à infecção por Toxoplasma gondii em caprinos dos estados do Pará e do Maranhão, Brasil
Parole chiave:
Toxoplasma gondii, Goat, Immunofluorescence antibody testAbstract
The epidemiology of toxoplasmosis in goats in the Amazon and pre-Amazon regions has been scarcely investigated, indicating that further studies are necessary to avoid losses in the production of small ruminants (due to factors such as: weight loss, low carcass yield and reproductive losses in the face of abortion cases), especially in the family context, as goat farming is the major income of small producers. Serum from 412 goats in Pará and Maranhão states were subjected to the Toxoplasma immunofluorescence antibody test for antibodies against Toxoplasma gondii. Of the total sample tested, 97 (23.5%) sera were positive for T. gondii. No statistical difference was found between the seroprevalence in Pará and Maranhão. The age of the animals showed a direct relationship with the prevalence of Toxoplasma infection. In Pará, farms where cats are fed placental remains and have access to the stable are 2.5 times more likely to be seropositive to T. gondii. In Maranhão, farms with more than six cats and those with goats older than 24 months of age are 4.5 and 2.0 times, respectively, more likely to be seropositive for T. gondii. Our results demonstrate that the sanitary handling of animals must consider the amount and access of cats to goats, and how to properly prevent the access and feeding of cats with placenta of goats. Animals older than 24 months were also considered an important risk factor associated with infection by T. gondii in goats.
