Nuevos registros de nematodes parásitos para Tropidurus torquatus (Squamata: Tropiduridae) de Argentina

Abstract

Los estudios concernientes a nematodes parásitos en lagartos de Argentina se han llevado a cabo principalmente en la región Noroeste y en la región de Cuyo, siendo escasos en la región Nordeste del país. En el presente trabajo se analizó la nematofauna parasitaria de 43 especímenes del lagarto Tropidurus torquatus (Squamata, Tropiduridae) en un área en proceso de urbanización en la periferia de la ciudad de Corrientes. Se hallaron un total de 239 nematodes en 28 lagartos (prevalencia total: 65,1%) pertenecientes a tres familias de órdenes diferentes: Parapharyngodon bainae (Pharyngodonidae, Oxyurida), Physaloptera tupinambae (Physalopteridae, Spirurida) y Oswaldocruzia sp. (Molineidae, Strongylida). De los mismos, se aportan datos referidos a sitio de infección, caracteres morfológicos y métricos, comentarios acerca de su distribución geográfica y hospedatoria, como así también, detalles sobre diferentes estructuras observadas mediante microscopía electrónica de barrido. Con este trabajo, se amplía la distribución geográfica de las especies P. bainae y Ph. tupinambae, constituyendo el primer registro de ambas especies para la Argentina.

Studies concerning to parasitic nematodes in lizards of Argentina have been done mainly in both the Northwest and Cuyo regions, being scarce in the Northeast region of the country. In the present work, the parasitic nematofauna from 43 specimens of Tropidurus torquatus (Squamata, Tropiduridae) was analyzed. The sampling site was an area under an urbanization process in the periphery of Corrientes city. A total of 239 nematodes was found in 28 lizards (total prevalence: 65.1%), belonging to three families in three different orders: Parapharyngodon bainae (Pharyngodonidae, Oxyurida), Physaloptera tupinambae (Physalopteridae, Spirurida), and Oswaldocruzia sp. (Molineidae, Strongylida). Data related to the site of infection, morphological and metric parasite features, comments about their geographical and host distribution, and details of structures observed with scanning electron microscopy are provided in the present study. This work represents the first record of P. bainae and Ph. tupinambae from Argentina.
