Plain-English summary
A study in Myanmar found that 25% of domestic dogs tested positive for canine parvovirus type 2 (CPV-2), a virus that causes severe gastrointestinal illness. The researchers collected samples from 143 dogs in shelters and hospitals over two years. They discovered that the strains of CPV-2 in these dogs were closely related to those found in other Asian countries, indicating a regional spread of this virus. This highlights the importance of monitoring and controlling CPV-2 to protect dogs from this serious disease.

Abstract
Canine parvovirus type 2 (CPV-2) causes severe gastroenteric disease in domestic dogs and wild canids. This study aimed to conduct molecular detection and characterization of CPV-2 in domestic dogs in Myanmar from December 2017 to October 2019. Rectal swabs (n = 143) were collected from domestic dogs from shelters and small animal hospitals in Yangon, Myanmar. CPV-2 detection was performed by a PCR assay targeting the VP2 gene. Our result showed that 25.17% (36/143) of swab samples tested positive for CPV-2. CPV-2 strains (n = 15) were selected for complete VP2 gene sequencing. Phylogenetic analysis showed that CPV-2 strains from Myanmar clustered together with Asian CPV-2c from China, Indonesia, Taiwan and Thailand but in separate clusters from CPV-2c from Europe and North America. Characteristic amino acid at residues 267Y and 324I were observed in CPV-2c strains from Myanmar, suggesting the Asian origin. In conclusion, our findings expanded the evidence of the predominance of CPV-2c in Southeast Asia. Thus, the surveillance of CPV-2 in domestic dogs in the countries and regions should be routinely conducted to provide epidemiological information for supporting prevention and control practices.
