Canine parvovirus type - 2 (CPV-2) infection is one of the most important viral diseases in dogs and wild carnivores causing severe haemorrhagic gastroenteritis in young ones. VP2 capsid protein plays an important role in determining the antigenicity and diversity of the virus. Although, several CPV variants emerged but new CPV-2a is the predominant circulating field strain of CPV in India. In the present study, new CPV-2a field strain (KLD3) isolated in cell culture was selected and the whole CPV VP2 gene was used for the expression in the E. coli expression system. Prokaryote expressing monocistronic DNA cassette containing open reading frame of whole CPV capsid gene (VP2) downstream of T7 promoter was synthesized. Analysis of the expression in E. coli cells showed the presence of capsid protein. Recombinant capsid protein showed immunoreactivity similar to the whole CPV virus antigen, when reacted with polyclonal antibodies against the whole CPV virus particles. The use of indigenously developed recombinant protein, being very economical, can be used to develop field kit. As the recombinant protein is not infectious, use of it for CPV serodiagnostic assay is considered safe.

Keywords: Canine parvovirus type - 2 (CPV-2), E. coli, CPV
