Brazilian laboratory rats and mice: decades pass, but parasite infections remain

ABSTRACT: Rats and mice are the most used experimental models in research. Globally, animal houses subjected to parasite outbreaks. In Brazil, parasitological profile is reflect sanitary condition of laboratory animals must be monitored frequently. The present study developed an integrative review scientific studies on rats facilities Brazil. It identified prevalent species reported from different geographic regions country, as well factors contributing perpetuation these parasites, proposed measures help prevent such infections. Based guiding question “which endoparasites ectoparasites have already been rat mouse colonies Brazil?” considering inclusion exclusion criteria, 28 published between 1974 2021 were selected four bases. These covered 12 Brazilian States, describing 16 genera parasites 18 rats. Most conventional type with few barriers, conditions may favor recurrence parasites. Efforts are, therefore, necessary for institutions accordance legislation practice optimal methodologies. this article can contribute change panorama national facilities, aiming safeguard quality data welfare.
