Anti-Toxocara spp. IgY antibodies in poultry sold in street markets from Feira de Santana, Bahia, Northeastern Brazil.

Since 1950, the human infection by parasites of the genus Toxocara, characterized by migration and permanence of larvae of the parasite in the liver, lungs, eyes, and brain, have been reported. The route of infection is the ingestion of embryonated eggs present in soil and contaminated vegetables, however there are reports of human illness associated with ingestion of viscera of paratenic hosts, including birds. This work aimed to detect the presence of larvae in the tissues and antibodies in the serum of poultry sold in street markets of Feira de Santana, Bahia, Brazil.
