Study of pathological effect of Newcastle disease virus isolated from upper respiratory system in broiler
This study was conducted to determine the pathogenicity of six local isolates of Newcastle disease virus (NDV) obtained form different area of Ninevah province. Isolation procedures employed via fertile chicken eggs inoculation. This study processed on the 4th passage of this isolate. Depending on t...

This study was conducted to determine the pathogenicity of six local isolates of Newcastle disease virus (NDV) obtained form different area of Ninevah province. Isolation procedures employed via fertile chicken eggs inoculation. This study processed on the 4th passage of this isolate. Depending on the embryonic lesion induced by this isolates, parallel with Mean Death time (MDT), Intravenous Pathogenicity Index (IVPI) and Intra Cerebral Pathogenicity Index (ICPI). The results
of the study demonstrate that four of the isolates were highly pathogenic, while the other two were mesogenics. The experimental infection using this isolate in broiler
chick revealed variability in respiratory signs and in mortality rates. However,
antibodies Hemagglutination titers (HI) showed elevation in all infected bird in the
first week post-infection (PI) and were more prominent in the second week of (PI). |
