| human vaccinia-like virus outbreaks in são paulo and goiás states, brazil: virus detection, isolation and identification. | since october 2001, the adolfo lutz institute has been receiving vesicular fluids and scab specimens of patients from paraíba valley region in the são paulo and minas gerais states and from são patricio valley, in the goiás state. epidemiological data suggested that the outbreaks were caused by cowpox virus or vaccinia virus. most of the patients are dairy milkers that had vesiculo-pustular lesions on the hands, arms, forearms, and some of them, on the face. virus particles with orthopoxvirus mo ... | 2004 | 15654477 |
| brazilian vaccinia virus strains are genetically divergent and differ from the lister vaccine strain. | vaccinia virus is responsible for an important zoonotic disease affecting dairy cattle and humans in brazil, but little is known about the origin, epidemiology and evolution of these brazilian vaccinia virus strains. in this work, seven brazilian vaccinia virus strains and the lister-derived brazilian vaccine strain, named lister-butantan, were compared based on the sequences of ten host range and virulence related genes. comparison of brazilian vaccinia virus strains with lister-butantan reveal ... | 2008 | 18248758 |

| could hantavirus circulation superpose areas of highly endemic vaccinia virus outbreaks? a retrospective seroepidemiological study in state of minas gerais. | hantavirus infections have been described in several regions in brazil through seroepidemiological studies. usually, populations are associated with rural and wild environment mainly due to close contact to species of sigmodontinae rodents, considered hantavirus reservoirs. | 2015 | 25626659 |
| serologic and molecular evidence of vaccinia virus circulation among small mammals from different biomes, brazil. | vaccinia virus (vacv) is a zoonotic agent that causes a disease called bovine vaccinia, which is detected mainly in milking cattle and humans in close contact with these animals. even though many aspects of vacv infection have been described, much is still unknown about its circulation in the environment and its natural hosts/reservoirs. to investigate the presence of orthopoxvirus antibodies or vacv dna, we captured small rodents and marsupials in 3 areas of minas gerais state, brazil, and test ... | 2017 | 28518030 |
