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
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
geographical analysis for detecting high-risk areas for bovine/human rabies transmitted by the common hematophagous bat in the amazon region, brazil.the common hematophagous bat, desmodus rotundus, is one of the main wild reservoirs of rabies virus in several regions in latin america. new production practices and changed land use have provided environmental features that have been very favorable for d. rotundus bat populations, making this species the main transmitter of rabies in the cycle that involves humans and herbivores. in the amazon region, these features include a mosaic of environmental, social, and economic components, which toget ...201627388498
serological investigation of rabies virus neutralizing antibodies in bats captured in the eastern brazilian amazon.in 2004 and 2005 a total of 38 cases of human rabies transmitted by the hematophagous bat desmodus rotundus were registered in the brazilian state of pará; 23 (60.5%) cases occurred in the northeastern region. because of this, a serological investigation for the antibodies of rabies virus was performed in municipalities of the northeastern state of pará, in order to assess whether the virus was circulating among different bat species.201324100701
serosurvey for selected viral infections in free-ranging jaguars (panthera onca) and domestic carnivores in brazilian cerrado, pantanal, and amazon.we investigated the exposure of jaguar (panthera onca) populations and domestic carnivores to selected viral infections in the cerrado, amazon, and pantanal biomes of brazil. between february 2000 and january 2010, we collected serum samples from 31 jaguars, 174 dogs (canis lupus familiaris), and 35 domestic cats (felis catus). serologic analyses for antibodies to rabies virus, canine distemper virus (cdv), feline immunodeficiency virus (fiv), and for feline leukemia virus (felv) antigen were co ...201323778599
