title: Rapid identification of Newcastle disease virus vaccine strains LaSota and B-1 by restriction site analysis of their matrix gene.
abstract: A region constituting 88% of the matrix gene of Newcastle disease virus vaccine strains LaSota and B-1 was amplified by reverse transcription-polymerase chain reaction. Amplified products of LaSota and B-1 strains derived from vaccine serials of different companies were digested with restriction enzymes MboI and HinfI. Strain characteristic cleavage site maps were obtained that allowed for a reliable and rapid differentiation between strains LaSota and B-1.
