Aim: Canine Parvovirus (CPV) is an emerging and re-emerging virus of canines. The study was undertaken to analyze VP2 gene of CPV in the isolates from dogs positive for CPV infection. Methods: The rectal swabs were collected from dogs suspected of CPV and subjected to PCR and nested PCR. The regions compared in the study were Punjab to represent north part of India and Assam to represent north-eastern part of India. The sequence analysis of VP2 gene of CPV was done using NCBI BLAST from the isolates which were positive for CPV by nested PCR. Further, phylogenetic analysis was done to understand the prevailing antigenic type of CPV from northern and north eastern part of India. Results: The sequence analysis revealed that all the sequences of VP2 gene from the samples had 98-99% homology with Canine Parvovirus and phylogenetic analysis revealed that CPV 2a antigenic type is circulating in both the regions selected in the study. Conclusions: The present study revealed that CPV 2a is circulating in the regions of Punjab and Assam part of India. Further sequence analysis of VP2 gene from more number of field isolates can throw better light on the prevailing antigenic type of CPV in various parts of India.
