| Abstract | ||||
| A natural outbreak of Newcastle disease (ND) in june, 1992 occured in breeding and growing quail flocks in College of agriculture farm, Assiut University. The clinical signs and post mortem lesions were recorded. Hamagglutinating viral agents were isolated in embryonated chicken eggs (ECE) and further identified as ND viruses by hemagglutination inhibition (HI) test. "to virus isolates (AG1 & AG2) were char. Sarized by physicochemical and biological testas viscerotrop < /strong>ic velogenic Newcastle disease (V..) viruses. Exp < /strong>erimental infection of virus isolates (AG1&AG2) in chikens and quails revealed that the viruses were more pathogenic for chickens than quails as indicated by high mortality and p < /strong>revalence of viscerotrop < /strong>ic lesions in chickens than quails. | ||||
