| detection of poxvirus in cattle associated with human cases in the state of rio de janeiro: preliminary report. | this preliminary report describes human and cow cases of poxvirus that recently occurred in the state of rio de janeiro. the electron microscopic findings were consistent with parapoxviral and orthopoxviral infection. orthopoxvirus strains were isolated from human and cow cases. detailed viral characterization by means of genetical techniques is under investigation. based on these informations, poxviral diseases should be also considered an emerging viral zoonosis that can affect human beings. | 2000 | 10998211 |
| an emergent poxvirus from humans and cattle in rio de janeiro state: cantagalo virus may derive from brazilian smallpox vaccine. | the biological properties of poxvirus isolates from skin lesions on dairy cows and milkers during recent exanthem episodes in cantagalo county, rio de janeiro state, brazil, were more like vaccinia virus (vv) than cowpox virus. pcr amplification of the hemagglutinin (ha) gene substantiated the isolate classification as an old world orthopoxvirus, and alignment of the ha sequences with those of other orthopoxviruses indicated that all the isolates represented a single strain of vv, which we have ... | 2000 | 11080491 |
| Human and animal infections by vaccinia-like viruses in the state of Rio de Janeiro: A novel expanding zoonosis. | Since 1999, vesicular infections caused by Orthopoxvirus in humans and animals, mainly in dairy cattle, have been identified in 20 municipalities in the Rio de Janeiro state of Brazil. This paper describes studies conducted in counties of the northwestern, middle-Paraíba Valley and southern regions of the Rio de Janeiro state where 77 human, 346 bovine and 78 rodent samples were collected over the past ten years. Laboratory investigations using virus isolation, electron microscopy, molecular bio ... | 2011 | 22185829 |
