Detection and differentiation of pigeon paramyxovirus serotype-1 (PPMV-1) isolates by RT-PCR and restriction enzyme analysis
Abstract Detection and pathotyping of Newcastle disease virus (NDV) is extremely important because the appearance of virulent virus has significant economic consequences. During 1981 to 1985, infections of racing and show pigeons with an avian paramyxovirus serotype-1 (APMV-1) hit worldwide, and a panzootic occurred due to a variant form of classical NDV. On the basis of pathogenicity and monoclonal antibody binding studies, the virus was termed ‘pigeon PMV-1’ (PPMV-1). In the past, number of Newcastle disease outbreaks in poultry and other birds has been attributed to PPMV-1. PPMV-1 viruses are known to present difficulty when assessed by conventional in vivo pathogenicity tests. In this study, the technique of reverse transcription-polymerase chain reaction (RT-PCR) and restriction enzyme (RE) analysis was used to detect and differentiate PPMV-1 isolates of Indian origin. Restriction enzyme digestion analysis of RT-PCR-amplified fusion protein (F) gene, encoding for the cleavage activation sites of fusion protein, was carried out with restriction enzymes BglI, HhaI, HaeIII, HinfI, MboI, MspI, PvuII and StyI. A set of only four enzymes HhaI, MspI or HaeIII, MboI and BglI alone were sufficient to differentially detect APMV-1 and PPMV-1 viruses and their pathotypes. In conclusion, RT-PCR followed by RE analysis proved to be useful for detection and differentiation of APMV-1 and PPMV-1 isolates at genomic level..
