Abstract

Although it is one of the most ancient diseases related in human history, rabies still presents a great challenge throughout the world. Wild animals have emergent importance in Brazil, and in this context the Northeast region of the Country has the better model to the epidemiologic study of wildlife rabies. In this region, the two independent virus variants maintained by terrestrial wildlife and presenting annual records of cases in the reservoirs species, other domestic and wild species and humans. These variants were initially identified in the State of Ceara and, to the present moment, are restricted to the Northeast region. The present study will be conducted by antigenic and molecular characterization of samples of the virus isolated from 14 cities endemic for wildlife rabies in Ceara State and by the detection of anti-rabies neutralizing antibodies in marmosets (Callithrix jacchus) and crab-eating-foxes (Cerdocyon thous) from the same State using different serologic techniques (Rapid Fluorescent Focus Inhibition Test - RFFIT, Simplified Fluorescent Inhibition Microtest - SFIMT and Fluorescent Antibody Virus Neutralization Test- FAVN). The aim of this study is the analysis of the laboratorial data obtained combined with information from the Epidemiological Surveillance Service from Ceara State, in order to provide information that will permit the implementation of more efficient measures for wildlife rabies prevention and control.
