OCCURRENCE OF Pachysentis sp. IN Nasua nasua FROM URBAN FRAGMENT OF CAMPO GRANDE, MATO GROSSO DOS SUL

Introdução

The description of the occurrence of parasites in wild and synanthropic animals, as in Nasua nasua, are important elements of biodiversity, and can be used as indicators of ecological age and diversity as more complete studies of biotic diversity in different geographic areas become available reinforcing the need for more information about the parasitic fauna. Nasua nasua synanthropic, generalist and opportunistic animal and the relationship of these animals with fauna and humans becomes increasingly and may pose several risks, especially when it comes to the spread of parasites.

Objetivo (s)

The aim of this study was to report the occurrence of parasitic gastroenteritis in Nasua nasua from a forested fragment of Campo Grande, MS.

Material e Métodos

In February 2023, one adult female coati from the conservation unit Parque Estadual do Prosa (PEP) was removed (Licence No. 85635-1/2022). Necropsy was performed and the gastrointestinal system was evaluated in the search for parasites.

Resultados e Conclusão

We found nine specimens of acantocephalans of the family Oligacanthorhynchidae in the terminal portion of the rectum and 14 specimens of cestoid (scolex) of the genus Taenia in the small intestine, identified by Travasso (1965) and Schmidt (1972). Specimens of Pachysentis sp. were identified based on the taxonomic keys proposed by Schmidt (1972) and Gomes et al (2019), characterized by subspherical proboscis with longitudinal rows, containing approximately 48 hooks and presence of lateral papillae at the base of the proboscis. The observed morphological characteristics are similar to Pachysentis lauroi, recently described in N. nasua from the region of Nhecolândia. In the scolex of specimens of Taenia, four suckers and the lack of rostellum and rostellar hooks were observed. Our results indicate that the free-living wild animals can be hosts of gastrointestinal helminths but, the study about helminths in coatis is still scarce.It is necessary that this study be deepened, mainly due to the increasing proximity of wild animals to humans.
