However, a group of four related sequences revealed only approximately 70% nucleotide identity to bat and human AstV sequences in the database, suggesting that these sequences were divergent from known PoAstV strains and possibly novel. Phylogenetic analysis of these sequences, in addition to prototypical animal AstV strains, confirmed their relatedness and grouped them in a unique lineage on a divergent branch distantly related to other known mamastroviruses (PoAstV 5 in Fig. 2a) . Phylogenetic analysis of the complete capsid coding region of PoAstV CC12 confirms that this strain forms a distinct lineage in the family Mamastroviridae, including previously identified porcine astroviruses from different continents (Fig. 2b ).	./cache/cord-004717-41ui4lqc.txt	./txt/cord-004717-41ui4lqc.txt
