## TL;DR

Researchers found microfilariae in two species of callitrichid primates in the Central Amazon, suggesting potential parasitic infections in these animals.

## Contribution

This study reports the incidental detection of microfilariae in Saguinus bicolor and Saguinus midas, contributing new data on parasitic prevalence in these primate species.

## Key findings

- 56.5% of Saguinus bicolor individuals had Dipetalonema or Mansonella microfilariae.
- 13.3% of Saguinus midas individuals showed presence of these microfilariae.

## Abstract

Callitrichid primates 
Saguinus bicolor
 and 
Saguinus midas
 from urban accidents in peri‐urban forests from Central Amazon were necropsied. Analysis of thoracic and peritoneal fluid showed that 56.5% (13/23) of 
S. bicolor
 individuals and 13.3% (4/30) of 
S. midas
 individuals had the presence of Dipetalonema and Mansonella (Tetrapetalonema) microfilariae.
