“…Our current results do not support these observations and suggest that all papillae are present on the external cuticular surface, totaling four cephalic papillae and two amphids. One pair of deirids was observed with the use of SEM, a structure also observed by Quentin (1973).…”

“…The anterior region presents a developed cuticular ring and cephalic structures, characterized as teeth or denticles described by LM (Ortlepp, 1924;Cosgrove et al, 1963;Quentin, 1973;Vicente et al, 1992;Alvarez et al, 1995). Our SEM analyzes show that these cephalic structures are not teeth or related structures.…”

“…Later, Cosgrove et al, (1963) described three pairs at the tip of the tail. Quentin (1973) showed two pairs of terminal papillae, with one pair of phasmids between these papillae. Amato et al, (1976) described three pairs of terminal papillae and did not mention the presence of the phasmid.…”

“…Spirura guianenses Ortlepp, 1924 was identified in this study based on analyzes of twenty females and twelve males using LM and SEM methods. Quentin (1973) described the presence of two amphids and eight cephalic papillae, four of which were internal and four external. Our current results do not support these observations and suggest that all papillae are present on the external cuticular surface, totaling four cephalic papillae and two amphids.…”

“…The first record of S. guianensis parasitizing a marsupial was noted in a Caluromys phylander (L.), which occurred in the region of Cayenne, French Guiana (Bain, 1972). This nematode was later identified in other marsupial species, collected in Suriname (Quentin, 1973), including Marmosa amarare 4 cinerea (Thomas) and Philander opossum (L.). S. guianensis was first reported in Brazil as infecting Philander opossum in Rio de Janeiro state (Amato et al, 1976).…”

Spirura genus Blanchard, 1849 comprise of nematode parasites that infect primate and marsupial species. Although several taxonomical studies have shown that the infection by this species occurs primarily in the esophagus of primates, evidence for the occurrence of these parasites in other hosts (marsupials, rodents and bats) has become the subject of investigation by several groups. In this work, we describe the presence of Spirura guianensis Ortlepp, 1924 in the marsupial Gracilinanus agilis (Marsupialia: Didelphidae) found in the Pantanal of Mato Grosso do Sul state of Brazil. Structural characteristics of this nematode were identified using light microscopy (bright field and fluorescence stereomicroscopy) and scanning electron microscopy (SEM) approaches. Details of the surface topography such as cephalic projections, ventral boss, details of the caudal papillae and cuticular ornamentations were shown, providing taxonomic characteristics that may help in the establishment of diagnostic protocols. In addition, the presence of this species in a new host and new geographical area of Brazil provide grounds for a revision on the distribution of S. guianensis in South America.

Necropsy of an adult, wild-born squirrel monkey (Saimiri sciureus) revealed 30 to 40 esophageal nematodes. The anterior end of each nematode was firmly attached to the mucosa, with the remaining portion free in the lumen. Histologic changes were limited to the superficial mucosa, where the epithelium adjacent to the nematode was hyperplastic and increased keratin formed a bridge over the body of the parasite. The nematode was identified as belonging to the genus Spirura. The number of parasites in this animal was considered significant and contributed to the death of the animal.Necropsy of an adult, wild-born squirrel monkey (Saimiri sciureus), that died at the Delta Regional Primate Research Center after a week in quarantine revealed 30 to 40 nematodes in the lumen of the esophagus. Although the animal was emaciated, no other significant gross lesions were noted. The anterior end of each nematode was firmly attached to the esophageal mucosa, with the remaining portion of the parasite lying free in the lumen. Nematodes were present throughout the esophagus but were especially numerous in the distal third.Histologic changes were limited primarily to the superficial mucosa. Numerous cross-sections of the parasite were seen (Fig. l), some of which were associated with the keratinized layer of the mucosal epithelium. The epithelium adjacent to the parasite was hyperplastic, and increased keratin formed a bridge over the body of the nematode (Fig. 2). Occasionally, the epithelium and lamina propria had a minimal to mild infiltration of neutrophils and lymphocytes associated with an embedded parasite. The only other histologic finding was minimal to mild edema of the submucosa.The nematodes recovered from the esophagus were identified as belonging to the genus Spirura, in the family Spiruridae, of the order Spirurida. Members of this genus possess a very characteristic ventral boss or hump (Fig. 3). Specimens collected
