| Abstract | ||
| A total of 34 samples were collected from chicken and pigeon flocks suspected to have Newcastle disease. NDV virus was isolated and identified by inoculation into the allantoic cavity of Specific–pathogen- free chicken eggs followed by hemagglutination and hemagglutination inhibition test. Furthermore, these isolates were geno-typically analysed using RT-PCR with specific primers flanking a 270 bp region representing the hypervariable region of F gene and the PCR-product was sequenced and compared to the previously published sequences. In this study, the F protein of 34 Saudi NDV isolates phylogram revealed clustering with NDVs representing lineage 2,4 and 5. | ||
