| الوصف: | Newcastle disease viruses (NDVs) possess a single-stranded, non-segmented RNA and are classified into different strains based on their level of pathogenicity. Due to slight differences in the molecular makeup of the viral genome among these strains, employing a pair of primers for molecular diagnostics becomes essential. This study aims to establish a new approach to detect potential NDV infection by developing molecular methods. This was accomplished by performing a single RT-PCR reaction utilizing a newly designed universal primer set targeting a remarkably conserved area within the viral M gene. Various tools and resources were utilized to generate a set of primers, including the NCBI database and the Geneious Inspirational Software for Biologists. Ninety-four oropharyngeal swabs were collected from 66 chickens and 28 pigeons showing signs of ND. Viral RNA was extracted from samples, and M genes were amplified using conventional RT-PCR and real-time quantitative RT-PCR (qRT-PCR), followed by genomic sequencing and bioinformatics. The designed primers exhibited good quality, as indicated by a Delta G value of less than -5. This suggests that the primers are unlikely to cause any issues during the PCR process. Moreover, the amplification of the M gene was achieved successfully in both conventional RT-PCR and RT-PCR for approximately all collected samples from chickens and pigeons. This successful amplification was further verified through genomic sequencing and subsequent sequence analysis. These findings provide confirmation that the designed universal primers can effectively identify and quantify NDVs using PCR assay. |
