Abstract
This is the first detailed description of Toxocara cati parasitizing felines in South America. Seventeen run over wild felines (Leopardus colocolo, Leopardus geoffroyi, Leopardus tigrinus, and Puma yagouaroundi) were collected from different towns in the State of Rio Grande do Sul, Brazil. The morphometry of males and females allowed the identification of specimens as being T. cati. The helminths were found in the stomach and intestine of hosts with prevalences of 66.6% in L. colocolo, L. geoffroyi, and L. tigrinus; and 60% in P. yagouaroundi. The ecological parameters were calculated for each host and L. colocolo had the highest infection intensity (22.5 helminths/ host). This is the first report of T. cati parasitizing four wild felines species in southern Brazil, besides a new record of this parasite for two host species.
Highlights
The genera Dujardinascaris Baylis, 1927; Neoascaris Travassos, 1927; Paradujardinia Travassos, 1933; Porrocaecum Railliet & Henry, 1912 and Toxocara Stiles, 1905 belonged to the family Toxocaridae Hartwich, 1954 (SPRENT, 1962; WARREN, 1971)
The genus Toxocara was proposed by Stiles in 1905, with the type species Lumbricus canis Werner, 1782 (= Toxocara canis Werner, 1782) (SPRENT, 1956)
Gallas and Silveira (2011) published data on the morphologic structures and their relationship to the body of T. cati. This is the first report of T. cati in wild felines of the species Leopardus colocolo Molina, 1782 and Leopardus tigrinus Schreber, 1775, as new hosts in South America
Summary
The genera Dujardinascaris Baylis, 1927; Neoascaris Travassos, 1927; Paradujardinia Travassos, 1933; Porrocaecum Railliet & Henry, 1912 and Toxocara Stiles, 1905 belonged to the family Toxocaridae Hartwich, 1954 (SPRENT, 1962; WARREN, 1971). The species Toxocara cati (Schrank, 1788) Sprent, 1956 is a parasite of carnivores from different geographic areas in the world. Gallas and Silveira (2011) published data on the morphologic structures and their relationship to the body of T. cati. This is the first report of T. cati in wild felines of the species Leopardus colocolo Molina, 1782 and Leopardus tigrinus Schreber, 1775, as new hosts in South America. Geoffory Saint-Hilaire, 1803, as a new host in the State of Rio Grande do Sul, Brazil
