WebbReassortment is the switching of viral RNA (gene) segments in cells infected with two different influenza viruses. The term recombination is often used incorrectly for the process of reassortment. Although reassortment occurs for influenza A, B and C viruses it does not occur among A, B and C virus types. The 1957 and 1968 pandemic viruses have … Webb24 jan. 2014 · These observations suggest the province-specific H9N2 virus gene pools increase the genetic diversity of H7N9 via dynamic reassortments and also imply that G0 has not gained overwhelming fitness ...
