Abstract

Abstract:

In order to understand the genetic variation of Canine parvovirus (CPV) in Anhui, the whole genome of 10 CPV strains collected in Anhui during 2018—2019 was amplified by PCR, and the genetic evolution characteristics of CPV and the variation of VP2 antigen in Anhui were analyzed by bioinformatics. Genetic evolution analysis showed that the 10 strains of CPV isolated in Anhui were mainly CPV-2c subtypes, originating from CPV-2AB004 (EF011664) and CPV-LZ1 (JQ268283), forming an independent branch. NS1 gene and VP2 gene showed an asynchronous phenomenon in the branch of genetic evolution, which provided the basis for the recombination of CPV gene. Amino acid mutation analysis revealed that VP2 protein of the CPV strain isolated from Anhui Province had some amino acid site mutations, and further research is needed to determine whether it has an impact on the structure and function of VP2 protein.This study provided reference for the study of CPV by analyzing the genetic evolution characteristics of CPV in Anhui Province and the amino acid site mutation characteristics of VP2 protein.

Key words: Canine parvovirus, whole genome, genetic evolution
