Analysis of mutations in the envelope gene of Moloney murine leukemia virus: separation of infectivity from superinfection resistance.

abstract：:Adsorption and one-step growth experiments performed with blue-green algal virus (BGAV) LPP-1 under normal conditions revealed a slow adsorption rate, in comparison with bacteriophage systems, followed by a 7-hour latent period. The burst size was approximately 100 virus particles per cell. The molecular weight of the...

Accumulating evidence also shows that B19 is detectable in nonerythroid lineage cells in vivo, but the mechanism of infection is still not clear. In this study, we explored the mode of B19 infection of human monocytic cell line U937. An in vitro infecti...
