Phylogenetic analysis of the partial RdRp protein sequence of astroviruses detected in human stool using pan-astrovirus PCR (region corresponds to aa 1192–1312 of ORF1ab of the reference HAstV-1 genome NC_001943, protein ID NP_059443). A representative of each astrovirus species belonging to mammalian Mamastrovirus and avian Avastrovirus genera were used as references. The tree was constructed by using the neighbour-joining method using amino acid p distances as implemented in mega4. The three species of HMOAstV are indicated by brackets. Reference sequences are labelled with diamonds. Bootstrap values >60 % are shown on the branches.
