OCORRÊNCIA DO VÍRUS DA RAIVA NA POPULAÇÃO SELVAGEM DE SAGUIS CALLITHRIX GEOFFROYI (HUMBOLDT, 1812) NO SUDESTE DO BRASIL

Abstract

Background: Zoonosis, which causes acute and lethal encephalitis, is transmitted through the inoculation of the virus present in the saliva of mammals of several species. In Brazil, wild rabies is a challenge for epidemiological surveillance and a significant increase has already been observed in human cases. Some of the main wild reservoirs are: wild dog (Cerdocyon thous), marmosets (Callithrix sp) and hematophagous bats (Desmodus rotundus). Considering cases of positivity in marmosets in the Northeast of Brazil, together with the increasing number of cases in wild animals, this work aimed to survey the occurrence of the virus in a wild population. The animals were necropsied from the tramway ES-060, all of the Callithrix geoffroyi. The material collected for analysis of the rabies virus consisted of brain, which was conditioned and identified for later analysis at the Institute of Agricultural and Forest Defense of Espírito Santo (IDAF). The 44 samples gave negative results. The study suggests that the occurrence of the virus should be investigated in other localities, especially in regions closer to sites that have already been reported cases of rabies, and that the use of trampled animals is feasible for a better understanding of wildlife health.
