Molecular surveillance of canine distemper virus in diarrhoetic puppies in northeast China from May 2014 to April 2015.

ABSTRACT: To trace the prevalence of canine distemper virus (CDV) in diarrhoetic dogs, a total of 201 stool samples were collected in the Heilongjiang province of northeastern China from May 2014 to April 2015. The 201 fecal samples were subjected to the detection of CDV by using RT-PCR targeting the partial N gene, phylogenetic analysis based on the complete H gene, and co-infection analysis. Results indicated that 24.88% (50/201) of the samples were positive for CDV. The fifty CDV samples exhibited an overall co-infection rate of 94% (47/50) with four enteric viruses (82%, 41/50) and five bacteria (72%, 36/50). The positivity rate of CDV exhibited differences among regions, seasons, ages and immunization status. Phylogenetic analysis of the complete H genes (n=6) revealed that the CDV strains iden
