Abstract excerpt
In chicken fibroblast cell (CEF) cultures with antiserum against Newcastle disease virus (NDV) strain TZ060107, the virus was passed serially for 50 passages in 3 independent lineages. HN and F genes were amplified and sequenced every 10 passages. The derived virus A1-50 with most mutations among 3 lineages was further passed for another 50 passages in CEF with or without antiserum against A1-50, each in 3...
