Evolution of the equine infectious anemia virus long terminal repeat during the alteration of cell tropism.

abstract：UNLABELLED:Since the 1960s, simian hemorrhagic fever virus (SHFV; Nidovirales, Arteriviridae) has caused highly fatal outbreaks of viral hemorrhagic fever in captive Asian macaque colonies. However, the source(s) of these outbreaks and the natural reservoir(s) of this virus remain obscure. Here we report the identifica...

abstract：:Infection of monkey cells with human adenovirus (Ad) is abortive, but the infection can be enhanced by coinfecting with simian virus 40 (SV40). However, in the coinfected monkey cells, Ad interferes strongly with SV40 DNA biosynthesis. This interference was found to be a reproducible, delicately controlled phenomenon ...
