| monoclonal antibody characterization of rabies virus strains isolated in the river plate basin. | in this study, 91 strains isolated in the river plate basin, south america, were examined from the epidemiological standpoint and with monoclonal antibodies (mabs) to the nucleocapsid of rabies virus. such strains reacted to mabs in accordance with nine different patterns (antigenic variants). rabies virus was isolated from 49 cattle, 21 dogs, 11 non-haematophagous bats, four vampire bats, two foxes, two horses, one buffalo, and one human. five of the variants had not been described previously. ... | 1997 | 9394612 |
| rabies virus maintained by dogs in humans and terrestrial wildlife, ceará state, brazil. | rabies viruses circulating in ceará, brazil, were identified by molecular analysis to be related to variants maintained by dogs, bats, and other wildlife. most of these viruses are associated with human rabies cases. we document the emergence of a rabies virus variant responsible for an independent epidemic cycle in the crab-eating fox (cerdocyon thous). | 2006 | 17326958 |
| characterization of rabies virus isolated from canids and identification of the main wild canid host in northeastern brazil. | the rabies cases in dogs and wild canids in northeastern brazil are a public and animal health problem. this paper describes the identities of the coding region of the n-gene of rabies virus (rabv) isolated in canids from northeastern brazil. the genetic tree generated using the sequence data described here divided the cluster brazilan canids into two subclusters (dog-related strains and wild canid-related strains) with identities greater than those already described. the two subclusters are sub ... | 2008 | 17889396 |
| molecular characterization of rabies virus isolates from dogs and crab-eating foxes in northeastern brazil. | thirty-eight samples of rabies virus isolated from dogs and crab-eating foxes (cerdocyon thous) in northeastern brazil were characterized genetically by analyzing the g gene and the psi region. the results show that there are two groups of rabies virus lineages circulating among domestic and wild animals in the region. the topologies of the phylogenetic trees of the g gene and psi region are similar and reveal the existence of geographic groups. the genetic diversity of the lineages isolated fro ... | 2009 | 19185599 |
| observations of sylvatic rabies in northern argentina during outbreaks of paralytic cattle rabies transmitted by vampire bats (desmodus rotundus). | during rabies outbreaks in cattle (paralytic rabies) in argentina associated with the common vampire bat desmodus rotundus, rabies was observed in marsh deer (blastocerus dichotomus), red brocket deer (mazama americana), capybara (hydrochoerus hydrochaeris), savanna fox (cerdocyon thous), and great fruit-eating bat (artibeus lituratus). rabies could constitute a threat to the survival of marsh deer in places where they live in small groups, and infection of both great fruit-eating bats and savan ... | 2009 | 19901391 |
| phylogenetic analysis of rabies virus isolated from canids in north and northeast brazil. | cases of canine rabies continue to occur in north and northeast brazil, and the number of notifications of rabies cases in wild canids has increased as a result of the expansion of urban areas at the expense of areas with native vegetation. in light of this, we performed molecular characterization of rabies virus isolates from dogs and cerdocyon thous from various states in north and northeast brazil. in all, 102 samples from dogs (n = 56) and cerdocyon thous (n = 46) collected between 2006 and ... | 2017 | 27671776 |
| fluorescent antibody test, quantitative polymerase chain reaction pattern and clinical aspects of rabies virus strains isolated from main reservoirs in brazil. | rabies virus (rabv) isolated from different mammals seems to have unique characteristics that influence the outcome of infection. rabv circulates in nature and is maintained by reservoirs that are responsible for the persistence of the disease for almost 4000 years. considering the different pattern of pathogenicity of rabv strains in naturally and experimentally infected animals, the aim of this study was to analyze the characteristics of rabv variants isolated from the main brazilian reservoir ... | 2015 | 26303004 |
| phylogeographic dispersion and diversification of rabies virus lineages associated with dogs and crab-eating foxes (cerdocyon thous) in brazil. | genetic lineages of dog-associated rabv still circulate in some areas of the north and northeast of brazil. in parallel, another rabv lineage circulates among wild canids in the northeast, particularly the crab-eating fox (cerdocyon thous). although previous studies and phylogenetic analyses have been carried out, the way in which these lineages are dispersed temporally and spatially remained to be elucidated. in this study, rabv n gene sequences isolated from canids in north and northeast brazi ... | 2013 | 23749047 |
| the emergence of wildlife species as a source of human rabies infection in brazil. | forty-five human rabies virus isolates from a wide geographical area of brazil were characterized using an anti-nucleoprotein monoclonal antibody panel and by partial nucleotide sequencing analysis of the nucleoprotein gene. three major antigenic groups related to the antigenic variants maintained in domestic dogs, vampire bats and marmosets were identified. phylogenetic analyses revealed that the viruses from dog-related cases segregated into four sister clades: three associated with dog-endemi ... | 2013 | 23433340 |
| a rabies virus vampire bat variant shows increased neuroinvasiveness in mice when compared to a carnivore variant. | rabies is one of the most important zoonotic diseases and is caused by several rabies virus (rabv) variants. these variants can exhibit differences in neurovirulence, and few studies have attempted to evaluate the neuroinvasiveness of variants derived from vampire bats and wild carnivores. the aim of this study was to evaluate the neuropathogenesis of infection with two brazilian rabv street variants (variant 3 and crab-eating fox) in mice. balb/c mice were inoculated with rabv through the footp ... | 2017 | 28831620 |
| global mammal parasite database version 2.0. | illuminating the ecological and evolutionary dynamics of parasites is one of the most pressing issues facing modern science, and is critical for basic science, the global economy, and human health. extremely important to this effort are data on the disease-causing organisms of wild animal hosts (including viruses, bacteria, protozoa, helminths, arthropods, and fungi). here we present an updated version of the global mammal parasite database, a database of the parasites of wild ungulates (artioda ... | 2017 | 28273333 |
