Estimation of population bottlenecks during systemic movement of tobacco mosaic virus in tobacco plants.

abstract：:The recently discovered hepatitis G virus (HGV) or GB virus C (GBV-C) is widely distributed in human populations, and homologues such as HGV/GBV-CCPZ and GBV-A are found in a variety of different primate species. Both epidemiological and phylogenetic analyses support the hypothesis that GB viruses coevolved with their...

The best-studied reservoir of latent virus in vivo is resting memory CD4(+) T cells, but it has recently been shown that CD34(+) hematopoietic progenitor cells (HPCs) can also become latently infected by HIV-1 in vitro and in vivo. ...
