## TL;DR

Researchers identified a zoonotic parasite in a type of Brazilian primate using molecular techniques.

## Contribution

This is the first molecular characterization of Balantioides coli in Brachyteles hypoxanthus in Brazil.

## Key findings

- Balantioides coli was identified in all seven fecal samples from Brachyteles hypoxanthus.
- An atypical variant of the parasite was predominantly found in the samples.

## Abstract

Fecal samples from seven individuals kept in semi‐captivity in Minas Gerais were subjected to microscopic and molecular parasitological techniques. Balantioides coli was identified in all samples with a predominance of an atypical variant. This is the first molecular characterization of B. coli in 
Brachyteles hypoxanthus
 in Brazil.
