First record of Lagochilascaris minor (Nematoda: Ascarididae) in Leopardus geoffroyi (Carnivora: Felidae) in Brazil.

Lagochilascariasis is a parasitic disease caused by nematodes of the genus Lagochilascaris. These parasites occur in the neotropical region and their definitive hosts are wild animals, domestic dogs and felids and, accidentally, humans. Here, infection by Lagochilascaris minor is recorded for the first time in a wild felid, in Brazil.
