| Summary: | <i>Cyclopes</i>, the smallest of all known anteaters, has an insectivorous diet and is arboreal, rarely descending to the ground. There are scarce reports on diseases and pathogenic agents affecting this taxon. Hemopathogens are pathogenic agents that inhabit the blood of various vertebrate species. Protozoa such as <i>Trypanosoma</i> spp., <i>Leishmania</i> spp., <i>Hepatozoon</i> spp., and members of the order Piroplasmida, as well as hemoplasmas and Rickettsial bacteria of the genera <i>Anaplasma</i> and <i>Ehrlichia</i>, are among the most important in this group. The transmission of these pathogens generally occurs through arthropod vectors, which act as intermediate hosts. In addition, infections caused by hemopathogens can have adverse effects on host health, contributing to population declines in susceptible species. This study investigated infection by protozoa and hemotropic bacteria in blood samples from free-ranging silky anteaters from Brazil, Peru, and Colombia using molecular detection methods. Sixteen samples were obtained during expeditions conducted in these countries. DNA was extracted from blood samples, and PCR assays were performed to detect parasites from the order Piroplasmida, <i>Hepatozoon</i> spp., trypanosomatid agents including <i>Leishmania</i> spp., <i>Trypanosoma evansi</i>, <i>T. cruzi</i>, and <i>T. vivax</i>, as well as hemotropic bacteria of the genera <i>Ehrlichia</i>, <i>Anaplasma</i>, and <i>Mycoplasma</i> sp. Nucleotide sequencing was performed on positive samples. Of the total samples analyzed, 62.5% (10/16) tested positive for hemotropic <i>Mycoplasma</i>, 50% (8/16) for <i>T. evansi</i>, and 6.2% (1/16) for <i>T. cruzi</i>. There is a significant gap in knowledge regarding the diversity of hemopathogens affecting the genus <i>Cyclopes</i>, and future studies are needed to understand how these infections may impact the health of individuals. |
