bat-transmitted human rabies outbreaks, brazilian amazon.we describe 2 bat-transmitted outbreaks in remote, rural areas of portel and viseu municipalities, pará state, northern brazil. central nervous system specimens were taken after patients' deaths and underwent immunofluorescent assay and histopathologic examination for rabies antigens; also, specimens were injected intracerebrally into suckling mice in an attempt to isolate the virus. strains obtained were antigenically and genetically characterized. twenty-one persons died due to paralytic rabie ...200616965697
molecular epidemiology of rabies virus isolated from different sources during a bat-transmitted human outbreak occurring in augusto correa municipality, brazilian amazon.we genetically characterize rabies virus (rabv) strains isolated from human cases, domestic and wild animals during a human outbreak of bat-transmitted rabies in augusto correa municipality, pará state, brazilian amazon in 2005. partial nucleotide sequences of the n gene (491 bp) were obtained for all strains, and phylogenetic analysis grouped these into two major clades (pará and central-southeast) and identified them as bat-related viruses genotype i, desmodus rotundus antigenic variant 3 (agv ...200817996263
molecular epidemiology of rabies from maranhão and surrounding states in the northeastern region of brazil.although many outbreaks of rabies have been reported in northern brazil, few epidemiological studies of these outbreaks have been undertaken. in this study, molecular epidemiological analyses were performed using 41 rabies virus samples isolated in the maranhão (ma), pará (pa), and tocantins (to) states of northeastern brazil. a 599-bp region of the glycoprotein (g) gene was first amplified from each sample by rt-pcr, then sequenced and subjected to phylogenetic analysis. a phylogenetic tree div ...200616773238
human rabies transmitted by vampire bats: antigenic and genetic characterization of rabies virus isolates from the amazon region (brazil and ecuador).since 2004, the main transmitter of human rabies in latin america has been the vampire bat (desmodus rotundus). based on the nucleoprotein of the rabies virus (rv), we analyzed antigenic and genetic profiles of isolates from 29 samples taken from humans living in different areas of the amazon region. two isolates were from ecuador and 27 from the northern and northeastern regions of brazil, which were obtained during outbreaks in various municipalities in the states of pará and maranhão in the y ...201020637811
virological and serological diagnosis of rabies in bats from an urban area in the brazilian amazon.the outbreaks of rabies in humans transmitted by desmodus rotundus in 2004 and 2005, in the northeast of the brazilian state of para, eastern amazon basin, made this a priority area for studies on this zoonosis. given this, the present study provides data on this phenomenon in an urban context, in order to assess the possible circulation of the classic rabies virus (rabv) among bat species in capanema, a town in the amazon basin. bats were collected, in 2011, with mist nets during the wet and dr ...201527049703
