The establishment of reverse genetic for non-segment negative single strand RNA viruses enabled Newcastle disease virus (NDV) to be the extremely attractive recombinant live viral vaccine candidates. In this study, NDV LaSota vaccine strain that has been widely used for control and prevention of Newcastle disease in chicken was rescued from genome cDNA clone by reverse genetic. The genome of LaSota, comprising 15186 nt, was cloned and sequenced prior to assembly into a full-length cDNA clone under control o...
