Abstract

Local pigeons pox virus (PPV) from naturally infected pigeon was isolated and identified. The isolated virus was inoculated on CAM of SPF and it produced specific pock lesion of pox virus pathogenicity test was applied by inoculating the isolated virus in susceptible squabs and it produced typical pox lesions. The isolated virus was identified by applying neutralization test and agar gel precipitation test using specific antisera. Comparataive polypeptide analysis was carried out on0 SDS-PAGE to identify the difference between the vaccinal strain (Hungarian) and the local field isolate. The polypeptide ranged from 194.2 and 20.0 kDa with total molecular weight (MW) of 1363.598 and and 1183.83 respectively for the two strains and the total viral protein of the two strains were estimated by using spectrophotometer and the values were 0.1353 g/dl and 0.1701 g/dl for the vaccinal and the local isolate strain respectively.
