| 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 |
| natural human infections with vaccinia virus during bovine vaccinia outbreaks. | bovine vaccinia is an exanthematic disease caused by vaccinia virus (vacv). this zoonosis has been associated with several cases of bovine infection, particularly in milk herds. farmers, milkers and their close contacts developed lesions on the hands, forearms, legs and face accompanied by fever, headache, malaise, myalgia and axillary, inguinal and cervical lymphadenopathy. vacv infections have a significant public health impact due to their occupational character, high frequency of transmissio ... | 2009 | 19243990 |
| intrafamilial transmission of vaccinia virus during a bovine vaccinia outbreak in brazil: a new insight in viral transmission chain. | bovine vaccinia (bv) is an emerging zoonosis caused by the vaccinia virus (vacv), genus orthopoxvirus (opv), poxviridae family. in general, human cases are related to direct contact with sick cattle but there is a lack of information about human-to-human transmission of vacv during bv outbreaks. in this study, we epidemiologically and molecularly show a case of vacv transmission between humans in são francisco de itabapoana county, rio de janeiro state. our group collected samples from the patie ... | 2014 | 24615135 |
