Occurrence of Ehrlichia canis in free-living primates of the genus Callithrix.

Bacteria of the genus Ehrlichia are Gram-negative and coccoid-shaped microorganisms that cause ehrlichiosis - a serious infectious disease that often leads to death. These bacteria present a strong zoonotic potential and primates may act as reservoir hosts. This study involved a molecular analysis to detect these microorganisms in blood samples collected from nineteen primates of the genus Callithrix living free in an Atlantic Forest fragment in the municipality of Viçosa, state of Minas Gerais, Brazil.
