Toxocara cati (Nematoda: Ascarididae) em Didelphis albiventris (Marsupialia: Didelphidae) do Brasil: Um caso de pseudoparasitismo

Abstract

Eggs of Toxocara cati were found in the feces of Didelphis albiventris from a peridomestic urban environment in Brazil. Negative fecal tests following short-term captivity of the opossums, as well as the absence of ascaridids during necropsy, suggest the occurrence of pseudoparasitism. Implications of the findings for the epidemiology of toxocariasis are discussed.
