Resumo
Os morcegos há algum tempo vem recebendo crescente importância em Saúde Pública, pois são considerados os principais reservatórios do vírus da raiva em grande parte do mundo inclusive no Brasil. Apesar dos morcegos manterem ciclos epidemiológicos da raiva há séculos, foi nas últimas décadas que a raiva em morcegos teve seu reconhecimento, por meio de pesquisas sobre o papel destes animais no ciclo epidemiológico da doença e também sobre suas variantes e suas implicações no desenvolvimento de novos reservatórios para o vírus da raiva, principalmente em regiões onde a doença em cães foi controlada. O estado de São Paulo, sob coordenação do Instituto Pasteur, realiza a vigilância epidemiológica para raiva por meio dos laboratórios credenciados para seu diagnóstico, no Laboratório do Serviço de Diagnóstico de Zoonoses da Faculdade de Medicina Veterinária e Zootecnia – UNESP - Botucatu - SP está credenciado recebendo material para diagnóstico de diversos municípios da região. Entre os anos de 2003 e 2010 foram diagnosticadas como positivas pelas provas de IFD e Prova Biológica, 19 amostras de quirópteros não hematófagos. Estes isolados foram caracterizados antigenicamente pelo painel de anticorpos monoclonais cedido pelo CDCOPAS (Centers of Disease Control and Prevention, Atlanta, GA, USAOrganização Pan-americana de Saúde), revelando que sete destes isolados pertenciam a variante 3, que tem os morcegos hematófagos da espécie Desmodus rotundus como reservatório, além de um morcego insetívoro do gênero Myotis que apresentou variante 4 característica do também morcego insetívoro Tadarida brasiliensis, além de outros três perfis não compatíveis, NC-1, NC-2 e NC-3. Todos os isolados foram submetidos a RT-PCR e seus produtos tiveram o gene da nucleoproteína (N) viral parcialmente...
For some time ago, bats are receiving an increased importance in Public Health because they are considered the main reservoirs of rabies virus around the world, including Brazil. Although bats remain the rabies epidemiological cycles for centuries, only in the last decades the rabies in bats had its recognition, throughout researches focused on the role of these animals in the epidemiological cycle of the disease and also on their variants and their implications in the development of new reservoirs for rabies virus, mainly in regions where the disease in dogs was controlled. The state of São Paulo, coordinated by the Institute Pasteur, performs epidemiological surveillance for rabies through registered laboratories for its diagnosis. The labs of Zoonosis Diagnostic Service, School of Veterinary Medicine and Animal Science - UNESP - Botucatu - SP is registered for receiving material for diagnosis of some municipalities of the region. Between 2003 and 2010, 19 samples of nonhematophagous bats were diagnosed as positive by IFD and Biological Evidence. These isolates were antigenically characterized by the panel of monoclonal antibodies donated by PAHO-CDC (Centers for Disease Control and Prevention, Atlanta, GA, USA Pan-American Health), revealing seven of these isolates belonged to variant 3, which has the vampire bat Desmodus rotundus as reservoir, as well as an insectivorous bat of the genus Myotis presenting variant 4, characterisitc of the other insectivorous bat Tadarida brasiliensis, and other three profiles are not compatible, NC-1, NC-2 and NC-3. All isolates were assayed by RT-PCR and their products had the nucleoprotein gene (N) viral partially sequenced, generating a phylogenetic tree that grouped these isolates into four clusters, designated as lineages Nyctinomops, Myotis, Desmodus rotundus, and a new lineage of rabies virus not...
