Molecular epidemiology of simian immunodeficiency virus SIVsm in U.S. primate centers unravels the origin of SIVmac and SIVstm.

ABSTRACT: Retrospective molecular epidemiology was performed on samples from four sooty mangabey (SM) colonies in the United States to characterize simian immunodeficiency virus SIVsm diversity in SMs and to trace virus circulation among different primate centers (PCs) over the past 30 years. The following SIVsm sequences were collected from different monkeys: 55 SIVsm isolates from the Tulane PC sampled between 1984 and 2004, 10 SIVsm isolates from the Yerkes PC sampled in 2002, 7 SIVsm isolates from the New Iberia PC sampled between 1979 and 1986, and 8 SIVsm isolates from the California PC sampled between 1975 and 1977. PCR and sequencing were done to characterize the gag, pol, and env gp36 genes. Phylogenetic analyses were correlated with the epidemiological data. Our analysis identified nine di
