Abstract
Enterovirus C96 (EV-C96) is a newer member of the species Enterovirus C. In this study, we determined the complete genome sequences of three EV-C96 isolates, one recovered from domestic sewage in 2013 and the other two isolated during surveillance of acute flaccid paralysis cases in 1991 and 2009, respectively. The complete genome sequences of these isolates were 75.6–84.2% identical to each other, 75.1–81.8% identical to the prototype strain, and 75.0–91.5% identical to other previously reported strains. Phylogenetic analysis of VP1 sequences revealed a high degree of genetic divergence among currently available EV-C96 sequences in the GenBank database, with an overall mean p-distance of 0.176. It is interesting to note that the 1991 strain 127/SD/CHN/1991 is the earliest EV-C96 isolate so far. Although EV-C96 is not frequently isolated during enterovirus surveillance, its great genetic diversity and the above findings suggest that this serotype has been circulating in China for many years.
