摘要: Rabies virus, the prototype species in family Rhabdoviridae, is a single-stranded, RNA, negative-sense, nonsegmented virus of genus Lyssavirus; it causal agent rabies, disease that has been poorly studied most developing countries (1,2). Nonetheless, Brazil implemented rabies control measures, and urban human transmitted by dogs cats, decreased from 73 cases 1990 to 17 2003 (3). Carnivores bats are primary reservoirs all continents, bat-transmitted relatively commonly diagnosed Latin American Caribbean (1,4–6).

Indeed, ≈39 reported United States since 1950s, Mexico, Chile, Colombia, Peru, Venezuela, New World (1,5,6,9,11,12). Although measures many South countries, transmission increased become public health concern, several detected. Outbreaks occurred remote areas Peru (5,13), Venezuela (9), more recently (7).
