RESUMO
The aim of this study was to report some external morphological features of Duboisiella proloba Baer, 1938. The parasites were collected during necropsy from the small intestine of Didelphis albiventris hunted in its native environment near Corrientes City, Argentina. Collected specimens of Duboisiella proloba were observed by light microscopy in order to be classified. Later the parasites were put into a 3% glutaraldehyde solution, dehydrated, dried by critical point, assembled, metallized, observed and photographed with a SEM. This is the first description of some external morphologic features of this species carried out by SEM in Argentina.

A case of caecum nematodiasis is described in a guinea fowl (Numida melagris) from the Municipal Zoo, Presidencia Roque Saenz Peña (Chaco) Argentina. Nematodes obtained from the caecum were observed in optic microscopy. According to their morphometric characteristics and location in the definitive host, were identified as belonging to the family Heterakidae, species Heterakis gallinarum, (Schrank, 1788) Maden, 1949.
