{Abstract}: BACKGROUND: The purpose of this study was to identify the species of artiodactyl host related to the fecal matter collected in a forest area in Rio de Janeiro state and carry out a parasitological investigation.
METHODS: Artiodactyl feces were collected between 2020 and 2021. The fecal samples were examined to identify the host through macroscopic and molecular analysis. The remaining samples were subjected to a fecal parasite analysis using microscopic techniques, and feces containing cysts of the phylum Ciliophora underwent a molecular analysis.
RESULTS: Of the 101 samples collected, 71.3% were found in Pavão Valley, the most anthropized area of the park. In the molecular analysis, 79 samples were identified as belonging to Sus scrofa and 2 as Mazama gouazoubira. The most frequently detected forms were cysts of the phylum Ciliophora (39.6%), followed by eggs of Ascaris spp. (11.8%) and Metastrongylus spp. (5.9%). Nucleotide sequences of Balantioides coli were characterized in 26 samples, and in 13 samples variants of type B0 and in 11 type A0 were identified.
CONCLUSIONS: It should be noted that this is the first study in the Americas that has identified B. coli in free-living S. scrofa feces, citing this bioinvader as one of the reservoirs of this parasite.
