Pesquisa de anticorpos anti-Toxoplasma gondii pelo teste de aglutinação modificada em frangos de corte abatido para consumo

Abstract

The toxoplasmosis is a zoonosis that affect man and domestic animals all over the world. The Toxoplasma gondii is an obligatory intracellular parasite which infects mammals and birds, has in felidae their definitive hosts. Toxoplasmic infection in birds can be asymptomatic, the most probable form of contamination through the ingestion of oocysts presente in soil, water and polluted rations and the chicken’s meat the one of the main transmission roads for the man. With the objective of surveying the occurrence of anti- Toxoplasma gondii antibodies in cut chickens abated for consumption in the metropolitan area of Belém, 300 serum samples coming from industrial and clandestine abbatoir houses, were submitted to the Modified Agglutination Test (MAT). Anti-T. gondii antibodies were detected in one (1/300, 0,33%) sample, coming from clandestine slaughter house and none coming from industrial slaughter house. Although the chicken’s meat coming from industrial slaughter house apparently doesn't offer risk for human contamination by T. gondii through ingestion, the adoption of the serologic research is recommended in any type of slaughtering and in the consumption level as prevention measure. Further studies are necessary to determine the importance of free birds breading as etep in the epidemiology of the toxoplasmosis.
