Development of plaque assays for hepatitis C virus-JFH1 strain and isolation of mutants with enhanced cytopathogenicity and replication capacity.

abstract：:Segment 7 (M) of the cold-adapted live influenza A virus vaccine plays a primary role in the ability of this virus to interfere with the replication of wild-type influenza A viruses. This conclusion is based on several lines of evidence. Single gene reassortant viruses derived by crossing influenza A/Ann Arbor/6/60 (H...
