Abstract
Amplification of avian paramyxovirus serotype 1 (APMV-1)-specific nucleic acid fragments, followed by restriction endonuclease analysis (REA) using Bgl I, was carried out to type strains according to their virulence. Primer sequences were used to amplify a 202 base pair fragment, encompassing the fusion protein cleavage site, in a one-step reverse transcriptase-polymerase chain reaction (RT-PCR) test for detection of a range of field cases and reference strains of APMV-1. Subsequent REA of the amplified fragments enabled differentiation of low virulent lentogenic field and vaccine strains from more virulent mesogenic and velogenic field strains of APMV-1, including pigeon PMV-1. In the present paper, we report the development and application of a one-step RT-PCR test coupled with REA as a fast, specific method for both the detection and typing of APMV-1 from field samples.Keywords
