| characterization of oliveros virus, a new member of the tacaribe complex (arenaviridae: arenavirus). | oliveros virus is an agent isolated in cell culture from bolomys obscurus (rodentia, muridae, sigmodontinae) captured on the central argentine pampa. oliveros virus was shown to be related to members of the tacaribe complex of the family arenaviridae by immunofluorescent antibody (ifa) tests, electrophoretic pattern of viral proteins, and morphology as observed by electron microscopy. it was distinct from 12 other arenaviruses by a combination of plaque-reduction neutralization tests, comparison ... | 1996 | 8615455 |
| new world arenavirus clade c, but not clade a and b viruses, utilizes alpha-dystroglycan as its major receptor. | alpha-dystroglycan (alpha-dg) has been identified as a major receptor for lymphocytic choriomeningitis virus (lcmv) and lassa virus, two old world arenaviruses. the situation with new world arenaviruses is less clear: previous studies demonstrated that oliveros virus also exhibited high-affinity binding to alpha-dg but that guanarito virus did not. to extend these initial studies, several additional old and new world arenaviruses were screened for entry into mouse embryonic stem cells possessing ... | 2002 | 11967329 |
| dynamics of oliveros virus infection in rodents in central argentina. | oliveros virus (olv) is an arenavirus hosted by the sigmodontine rodent, necromys benefactus, in central argentina. we report a 3-year longitudinal field study of the dynamics of olv infection in host populations from 15 localities in two provinces on the central argentine pampa. there was an overall 3-year period immunofluorescent antibody prevalence of 25% in the host population, and infected hosts were found throughout the study area. spill-over infection into common sympatric species was rar ... | 2007 | 17760514 |
| co-circulation of clade c new world arenaviruses: new geographic distribution and host species. | clade c, of the new world arenaviruses, is composed of only the latino and oliveros viruses and, besides the geographic range of their rodent reservoirs, the distribution of these viruses has been restricted to bolivia and argentina. in this study, the genetic detection and phylogenetic analysis of the complete s segment sequences of sympatric arenaviruses from brazil revealed a new geographic distribution of clade c arenaviruses, as well as the association of oliveros virus with a new rodent re ... | 2015 | 25975978 |
| oliveros virus: a novel arenavirus from argentina. | during the past few decades several newly recognized rodent-borne arenaviruses have been shown to be associated with severe hemorrhagic fever cases in south america. changes in ecology and farming practices throughout the region have increased the concern over the potential public health threat posed by such emerging virus diseases. oliveros (olv) virus is a recently discovered arenavirus of the rodent bolomys obscurus in argentina. genetic analysis of the small genomic rna segment, which encode ... | 1996 | 8599223 |
