Abstract in Portuguese
No Brasil e em alguns países da América Latina, a incidência de raiva transmitida por animais domésticos tem diminuído enquanto tem aumentado em animais silvestres. Durante os últimos anos, no Brasil, a raiva tem sido diagnosticada em morcegos hematófagos ou não, primatas não-humanos, cachorros-do-mato, quatis, guaxinins, capivaras, cervos, gambás e outras espécies silvestres. O presente estudo foi realizado em parceria com biólogos, pesquisadores na área de monitoramento de fauna silvestre, e o objetivo foi pesquisar a presença do vírus rábico em mamíferos silvestres de vida livre, provenientes de uma reserva natural particular, localizado no município de Ribeirão Grande, São Paulo, região que já foi alvo de raiva nos últimos anos. Durante o período de 2002 a 2004, 104 amostras de cérebro de animais capturados foram enviadas para diagnóstico no Laboratório de Raiva da UNESP de Araçatuba, SP, acondicionadas em pipetas plásticas do tipo Pasteur individuais. Os animais pertenciam a três ordens, Chiroptera (47,1%), Rodentia (46,2%) e Marsupialia (6,7%), sendo de diferentes idades e sexos. As amostras foram submetidas ao teste de imunofluorescência direta e inoculação intracerebral em camundongos e todas apresentaram resultado negativo para a raiva. Segundo dados da Coordenação do Programa de Controle da Raiva do Estado de São Paulo a raiva é endêmica na região estudada e a porcentagem de positividade em morcegos nos últimos dez anos é de 1,8%. Embora dos diagnósticos tenham sido negativos neste estudo, não é possível afirmar que o vírus rábico não circula naquela propriedade

Abstract in English
In Brazil and some Latin American countries, the incidence of rabies transmitted by domestic animals has decreased while it has been increasing in wild animals. During the last few years rabies has been diagnosed in hematophagous or nonhematophagous bats, nonhuman primates, crab-eating foxes, coatis, raccoons, capybaras, deers, skunks and some other species. The present study was carried out with biologists, researchers in wild fauna monitoring and the objective was to search the presence of the rabies virus in wildlife mammals from a private natural reserve, in Ribeirão Grande city, SP, region that was target of rabies in the last few years. During 2002 to 2004, 104 brain samples of captured animals were sent for diagnosis to UNESP Rabies Laboratory from Araçatuba, SP, conditioned in individuals Pasteur plastic pipettes. The animals belonged to three different orders, Chiroptera (47,1%), Rodentia (46,2%) and Marsupialia (6,7%), and to different ages and sex. The samples were submitted to direct fluorescent antibody test and mouse inoculation test and all samples resulted negative for rabies. According to data of the Rabies Control Program Coordination from São Paulo State, rabies is endemic in the studied region and the percentage of positive cases in bats during the last 10 years was 1,8%. Although all diagnosis were negative in this study, it is not possible to affirm that the rabies virus do not circulate in that property
