Abstract :

Avian pox virus represents a large group of virus which belongs to the pox viridae family. This virus mainly infect and cause diseases in the poultry which causes economic losses to the poultry industry. The present work is based on the analysis of field fowl pox virus with attenuation of different passages in ECE’s. For this, the sample was collected from the infected birds and the fowl pox virus was cultured in emyonated chick egg and its virulence was seen at different passages like 3, 6 & 9. As a result the attenuation of virus in ECE reduces its virulence by increasing the number of passages. The same was observed in the PCR product with decreasing the length of DNA and the effective vaccination process was observed with 9 times passaging in ECE’s.
