Abstract
Porcine epidemic diarrhea virus (PEDV) causes severe diarrhea and dehydration in suckling pigs and has caused high rates of death among piglets and substantial economic loss in Vietnam since 2009. To investigate the genotypes of prevailing PEDVs, intestinal and fecal samples from piglets from central and northern Vietnam were collected and analyzed. Phylogenetic analysis of the nucleotide sequences of complete spike genes of PEDVs from Vietnam resulted in the identification of two divergent groups. PEDVs (HUA-PED45 and HUA-PED47) belonged to the G2b group, along with Chinese, US, and Korean strains occurring at the end of 2010, in May 2013 and in November 2013, respectively. Six strains from the Quang Tri region were assigned to the G1b group, along with Chinese and US strains. The Vietnamese PEDVs detected in infected piglets had a nationwide distribution and belonged to the G2b and G1b genotypes.Entities:
