The species
Enterovirus G (formerly named Porcine
enterovirus B) consists of a sixteen
(sero)types: EV-G1 to EV-G16 (Table
1).
The original PEV-1 to 7 and 11 to 13 have been reclassified and assigned to a new genus, Teschovirus; PEV-8 has been renamed porcine sapelovirus 1 and reclassified in the species Porcine sapelovirus, genus Sapelovirus. Examples of EV-G1 (KY498016 & KY498017) have been found which contain an inserted porcine torovirus-like papain-like cysteine protease (PLCP) coding region inserted between 2C and 3A (Knutson & Marthaler, unpub.). Another example of a PLCP insert in the same region of a candidate novel EV-G type (Shang et al., in press); interestingly the two PLCP regions only share 87% nt and 86% aa identities. A recently described enterovirus found in a goat in China (Wang et al., 2017) is probably a new EV-G type (N.J. Knowles, unpub. data). Table 1.
