Helminths Parasites from Mico melanurus (Geoffroy, 1812) from Cerrado Biome

Résumé fourni par la source

Brazil has a high abundance of monkey species, including Mico melanurus. In general, primates are vulnerable to parasites owing to their behavior. We aimed to identify the occurrence of gastrointestinal parasites in M. melanurus in the Brazilian Cerrado and to perform morphometric and morphological analyses of these helminths. Helminths of 21 M. melanurus were collected from Cuiabá in the Brazilian Cerrado. The animals were found dead within the urban perimeter, necropsied, and tested for parasites. Parasites found in the gastrointestinal tract were fixed in 70% ethanol for morphological identification. We identified Trypanoxyuris spp. in two samples (mean intensity of 63 and mean abundance of 6.3) and Primasubulura jacchi in the other 18 samples (mean intensity of 34.22 and mean abundance of 30.8). One sample was deteriorated; therefore, it was not necropsied. P. jacchi infections in same cases are asymptomatic or have gastrointestinal signs such as diarrhea. Trypanoxyuris spp. are commonly found in the primates of Mato Grosso. Only these two parasites were identified, provided by a small parasite richness, and were associated with the impact of habitat fragmentation in an anthropized area, indicating an imbalance in the environment in which they lived.
