Abstract

Since its emergence, Canine Parvovirus type 2 (CPV-2) has been considered as a deadly pathogen in dogs with high mortality in puppies for its clinical gastroenteritis and severe haemorrhagic diarrhoea. Although several studies on CPV-2 were conducted in Bangladesh, molecular investigation is poorly understood. The aim of the study was molecular detection and phylogenetic analysis of CPV in diarrhoeic pet dogs. During Jan-July 2019, anal swabs were collected from 96 unvaccinated pet dogs with suspected CPV infection from Sylhet region of Bangladesh. The CPV infection was initially screened through rapid Immunochromatographic (IC) strip test, and then CPV-2 (VP2 gene) were detected by conventional PCR assay. Then the nucleotide sequence of amplified VP2 gene was compared with other CPV strains from GeneBank. Of the total samples, 17.7% (17/96) found positive in IC strip test, and 15.62% (15/96) were found positive in PCR assay by using primer pair P2 that detect original CPV-2 type. The IC test showed 100% sensitivity and 97.5% specificity with PCR. In sequence analysis, our isolates showed the highest 90.40% homology with the isolates of China and the USA. Our strains had also an evolutionary relationship with the other strains of CPV from China and India. This study demonstrates the presence of CPV-2 in Bangladesh and futher sequence analysis of more VP2 gene will help in details insight of the molecular and genetic evolution of CPV in Bangladesh.
