[Cammalanus Railliet and Henry, 1915 (Nematoda, Camallanidae). Parasite from Hydrodynastes gigas (Reptilia, Serpentes, Colubridae) from Argentine Chaco].

Abstract

Adult specimens of Camallanus genus (Nematoda, Camallanidae), parasitizing a Hydrodynastes gigas (Serpentes, Colubridae) from Chaco in the North East of Argentina, are described for the first time. The morphologic and morphometric parasitological studies were carried out using diaphanization by lactophenol technique. The specimens described were drawn and photographed. With this investigation the analysis of the reptilian pathologies, the knowledge of which is necessary to make projects, to manage and control the biomedic aspects in breeders, zoos and/or reserves has started. Thus, it enables us to know associated nematofauna providing facts about the biodiversity of nematode parasites of reptiles.
