摘要
Porcine astrovirus (PAstV) is broadly distributed in pigs in several countries worldwide. PAstVs belong to the genus Mamastrovirus and are divided into five genetically divergent types. This study presents a molecular characterization of PAstV identified in diarrheic piglets in South Korea. The complete genome of the Korean PAstV strain KOR/KNU14-07/2014 was sequenced and analyzed to characterize PAstV circulating in South Korea. The full-length genomic sequence of KNU14-07 was determined to be 6,337 nucleotides in length and consisted of three major open reading frames (5′-ORF1a-ORF1b-ORF2-3′). The overall degree of nucleotide sequence identity was 40.8 to 72.5 % between KUN14-07 and other reported PAstVs, indicating high heterogeneity among PAstVs. Genetic and phylogenetic analyses showed that the KNU14-07 strain was most closely related to the PAstV2 lineage, which is the second most common type in South Korea.
