- Abstract
Duck virus enteritis (DVE) is an acute, contagious herpes viral disease of ducks, geese and swans and members of the family Anatidae under the order Anseriformes. As per the recent taxonomic classification by ICTV, DEV has been classified into the genus Mardivirus, subfamily Alpha-herpesvirinae of the family Herpesviridae. Vaccination is the only option for the prevention and control of Duck plague. In India vaccination is done with chicken embryo adapted live virus which has many shortcomings. So, in this present situation a safe and potent vaccine development is the need of the hour. The use of chicken embryo fibroblast and a certified cell line may, probably, be the best option to achieve this. Therefore, the present study was undertaken for adaptation and propagation of local strain of duck plague virus in various cell culture systems. During the study a wild strain of DPV (DP/As-Km/0019) which was isolated in Duck Embryo Fibroblast, available in the Department of Microbiology was selected. The selected wild strain was used for adaptation in various cell culture systems viz. Chicken embryo fibroblast cell culture (CEF), Vero cell line and QT-35 cell line. The virus was passaged up to 12th passage levels and the presence of viral antigen was demonstrated by appearance of cytopathic effect (CPE), by Polymerase Chain Reaction (PCR) and by Sandwich ELISA. PCR was able to detect virus from all the cell cultures from 5th passage onwards and virus titre was detected at 10th and 12th passage level by S-ELISA. It was observed that various cell culture systems can be a good candidate for propagation of DPV and further study is required to study its immunogenicity and its feasibility as a vaccine candidate.
