Detection and genotyping of canine parvovirus in domestic dogs in Viet Nam

Abstract

Canine parvovirus (CPV) is one of the most important pathogens causing enteritis in domestic dogs. Although, there were a few reports of CPV in Viet Nam, recent information on CPV infection in domestic dogs in Viet Nam is limited. The aim of this study was to update information of CPV-2 types in domestic dogs in Viet Nam. A total of 44 CPV-2 strains were collected from provinces in the Northern, Central and Southern of Viet Nam using for genetic analysis to
determine type of CPV-2. The studied results indicated that CPV-2c was predominant type circulating in domestic dogs in Viet Nam (97.7%). In addition, this study also determined new CPV-2a strain circulating in the Central of Viet Nam with a low rate (2.7%). Genetic analysis showed that CPV-2c belonged to the Asian CPV-2c group and had a high level of amino acid similarity (99.4-100%) with new variant CPV-2c strains from China. The results indicated that there was an evolution of Vietnamese CPV-2 and transmission between neighbor countries.
