Ectoparasites of opossum's (Didelphimorphia: Didelphidae) captured in an urban complex in the Northern Brazilian amazon: new hosts and research on hemotropic bacteria.

Ticks and mites are important ectoparasites that affect animal and human health, directly causing harm and acting as vectors of pathogens. This study investigated the ectoparasites of synanthropic didelphids marsupials in northern Amazonia, Brazil, and screened them for hemotropic bacteria. The study was carried out in October 2022 in the metropolitan region of Macapá, Amapá State, Brazil, in vegetation remnants characterized by terra firme rainforest, alluvial forest, and savanna.
