1 Identification of a novel cosavirus species in faeces of children and its relationship with acute gastroenteritis in China  J.-M. Yu, Y.-Y. Ao, L.-L. Li, Z.-J.

2 Fig. 1 (a) Genome organization of Cosa-CHN. (b) Whole virus sequencing approach. (c) Protein cleavage map. Nine fragments were used to produce final genome sequence. Potential cleavage sites of Cosa-CHN are similar to those of HCosV B. Location of initial PCR for HCosV and Cosa-CHN specific reverse-transcription nested PCR amplicon products are indicated in red and marked as VP1 and VP3/VP1 respectively. Cosa-CHN, novel human cosavirus; HCosV, human cosavirus.

3 Fig. 2 Phylogenetic analysis of Cosa-CHN sequences. (a) Polyprotein amino acid sequences. (b) Partial VP3/VP1 nucleotide sequences. Tree was constructed using neighbour-joining method by MEGA5 software with 1000 bootstrap replicates. Sequences from this study are indicated by solid circles. Cosa-CHN formed lineage distinct from other known HCosV. Cosa-CHN, novel human cosavirus; HCosV, human cosavirus.
