common vampire bat attacks on humans in a village of the amazon region of brazil.many people in amazonian communities have reported bat bites in the last decade. bites by vampire bats can potentially transmit rabies to humans. the objective of this study was to analyze factors associated with bat biting in one of these communities. a cross-sectional survey was conducted in a village of gold miners in the amazonian region of brazil (160 inhabitants). bats were captured near people's houses and sent to a lab. of 129 people interviewed, 41% had been attacked by a bat at least o ...200111784915
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
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
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
rabies: knowledge and practices regarding rabies in rural communities of the brazilian amazon basin.the occurrence of outbreaks of human rabies transmitted by desmodus rotundus in brazil in 2004 and 2005 reinforced the need for further research into this zoonosis. studies of knowledge and practices related to the disease will help to define strategies for the avoidance of new cases, through the identification of gaps that may affect the preventive practices.201626927503
first detection of leishmania spp. dna in brazilian bats captured strictly in urban areas.leishmania spp. is a protozoan that maintains its life cycle in domestic and wild animals and it may include bats, a population that has increased in urban environments. this study aimed to investigate the presence of leishmania spp. in bats captured strictly in urban areas that are endemic for visceral leishmaniasis. the spleen and skin samples of 488 bats from 21 endemic cities in northwestern são paulo state, brazil, were tested for the presence of leishmania kdna using real-time pcr. differe ...201526209107
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
