Descripción
In the Argentinean Gran Chaco, numerous investigations have dealt with the diversity of vertebrates, including amphibians and reptiles. The parasitofauna of these organisms, has been more studied in some groups such as amphibians; however, from a biogeographic perspective, most of these studies were carried out in the Humid Chaco. The goal of this work is to present the nematofauna found in six species of amphibians, Rhinella diptycha, Chacophrys pierottii, Ceratophrys cranwelli, Scinax nasicus, Leptodactylus bufonius, and Odontophrynus lavillai, collected in different locations within the Dry Chaco, in the department of Matacos, Formosa, Argentina. In a total of 34 amphibians analyzed, we found 1,526 parasitic nematodes (total prevalence: 61.7%; total mean intensity: 72.6±90.3; total mean abundance: 44.9±78.9), belonging to 9 taxa: adults of Rhabdias sp., Oswaldocruzia sp., O. subauricularis, Schulzia travassosi, Aplectana hylambatis, Cosmocerca podicipinus, Oxyascaris caudacutus, Schrankiana formosula, and larvae of Physaloptera sp. These nematodes were collected from the lungs, small intestine, large intestine, gastric mucosa, and gallbladder of hosts. This work is the first record of helminths from C. pierottii and O. lavillai and the first record of nematodes from Ce. cranwelli throughout its geographical range. The species Schrankiana formosula (Atractidae) is recorded for the first time in Argentinean amphibians. Thus, we expand the knowledge of the biological diversity of helminth parasites of amphibians from the Dry Chaco ecoregion. This base-line information, would allow to understand the factors that influence the patterns of host and geographic distribution of vertebrate parasites in an area with extreme characteristics such as the Dry Chaco.
Contribuciones al conocimiento de nematodos parásitos de anfibios de la ecorregión Chaco Seco de Argentina. En el Gran Chaco Argentino, numerosas investigaciones han tratado la diversidad de los vertebrados, incluida su fauna herpetológica. En cuanto a la parasitofauna de estos organismos, algunos grupos como el de los anfibios han sido más estudiados; sin embargo, biogeográficamente, la mayor parte de estos estudios fueron realizados en el Chaco Húmedo. El objetivo de este trabajo es presentar la nematofauna hallada en seis especies de anfibios, Rhinella diptycha, Chacophrys pierottii, Ceratophrys cranwelli, Scinax nasicus, Leptodactylus bufonius y Odontophrynus lavillai, colectadas en distintos puntos del Chaco Seco en el departamento de Matacos, Formosa, Argentina. En un total de 34 anfibios analizados encontramos 1.526 nematodes parásitos (prevalencia total: 61,7%; intensidad media total: 72,6±90,3; abundancia media total: 44,9±78,9), pertenecientes a 9 taxones, adultos de Rhabdias sp., Oswaldocruzia sp., O. subauricularis, Schulzia travassosi, Aplectana hylambatis, Cosmocerca podicipinus, Oxyascaris caudacutus, Schrankiana formosula y larvas de Physaloptera sp. Estos nematodos se colectaron de los pulmones, el intestino delgado, el intestino grueso, la mucosa gástrica y la vesícula biliar de los hospedadores. Este trabajo constituye el primer registro de helmintos para C. pierottii y O. lavillai y el primero de nematodes para Ce. cranwelli en toda su área de distribución geográfica. La especie Schrankiana formosula (Atractidae) es registrada por primera vez en anfibios argentinos. De este modo, ampliamos el conocimiento de la diversidad biológica de los helmintos parásitos de anfibios de la ecorregión Chaco Seco. Esta información permitirá conocer cuáles son los factores que influyen en los patrones de ocurrencia en hospedadores y distribución geográfica de helmintos parásitos de vertebrados, en un área con características tan extremas como el Chaco Seco.
