Cross-species transmission of simian foamy virus (SFV) to human beings from chimpanzees, baboons, and African green monkeys has been described. Although macaques are the non-human primate most often handled in research, human infection with SFV from macaques has not been reported. Two of 46 primate-facility workers tested positive for antibodies that(More)
The proviral genome of the 32H reisolate of simian immunodeficiency of macaques (SIVmac32H) has been cloned and sequenced. Including both long terminal repeats, it is 10277 base pairs in length and contains open reading frames for all known SIV genes (gag, pol, vif, vpx, vpr, tat, rev, env and nef). This is the first report of an infectious SIVmac molecular(More)
A vaccine against AIDS will probably have to protect against challenge both by viable virus-infected cells and by cell-free virus. Eight cynomolgus macaques infected with attenuated simian immunodeficiency virus (SIV) were challenged (four each) with cell-free and cell-associated SIV. All were protected, whereas eight controls were all infected after(More)
The brain is assumed to be a sterile organ in the absence of disease although the impact of immune disruption is uncertain in terms of brain microbial diversity or quantity. To investigate microbial diversity and quantity in the brain, the profile of infectious agents was examined in pathologically normal and abnormal brains from persons with HIV/AIDS [HIV](More)
HIV infection is characterized by a host response composed of adaptive and innate immunity that partially limits viral replication; however, it ultimately fails in eradicating the virus. To model host gene expression during acute HIV infection, we infected cynomolgus macaques with the SIV/HIV-1 chimeric virus, SHIV89.6P, and profiled gene expression in(More)
New viral infections in humans usually result from viruses that have been transmitted from other species as zoonoses. For example, it is accepted widely that human immunodeficiency virus (HIV) is the result of the propagation and adaptation of a simian immunodeficiency virus (SIV) from nonhuman primates to man [1]. Previously, we reported productive(More)
