Diversity and prevalence of intestinal parasites of zoonotic potential in animal hosts from different biomes in the central region of Brazil.

The Brazilian state of Mato Grosso comprises the biomes Cerrado, Pantanal, and Amazon rainforest. The animals that make up the biodiversity of these biomes have an ongoing relationship with domestic animals. This study aimed to describe the prevalence and diversity of intestinal parasites in different class of animal hosts, domestic and wild, from the three biomes of Brazil's central region, during 2019. We analyzed animal faecal samples by sedimentation tests and centrifugal flotation in sucrose. The Shannon index test to calculate diversity and equitability, was used. In the 280 samples analyzed, 79.64% was positive. Domestic animals showed positivity of 87% and wild animals of 51%, being mammals the most prevalent, with 81%. Blastocystis sp. was the most prevalent protozoan, and Ascaris sp. of the helminths. Shannon's indexes were higher for the Pantanal. Overall, pigs, cows, and chickens had high prevalence values and diversity and equitability of enteroparasites. Due to the great diversity of parasites found in pigs, cows and chickens, these animals can play an important role in the transmission and maintenance of the infection to other mammals, including humans.
