Astrovirus (AstV) infections are among the most common causes of gastroenteritis and are also associated with extraintestinal manifestations in humans and many animals. Herein, for the first time, the complete genome sequence of newly identified porcine astrovirus genotype 3 (PAstV3) strain US-MO123 was determined. Sequence comparison and phylogenetic analysis showed that PAstV3 has the closest relationship with mink AstV and the human AstV strains VA1, VA2, and SG, indicating the same ancestral origin and zoonotic potential of the virus.
