- Abstract
In this study, 396 samples from diarrheic pigs on 46 pig farms in Jiangsu Province, China, were analyzed by RT-PCR. One-hundred eighty-one pigs from 37 farms tested positive for porcine kobuvirus (PKV). Phylogenetic analysis of the 3D gene from 19 isolates showed sequence homology of 88.0 %-100 % and 69.4 %-100 % for nucleotides and amino acids, respectively, while similarity to isolates of other kobuviruses was 69.6 %-78.8 % and 27.8 %-56.9 %, respectively. One-hundred eighty-five samples contained two or more pathogens, and 31/68 PKV-positive samples tested positive for other diarrheic pathogens, confirming the existence of PKV infection and coinfection.
