Porcine enteroviruses (PEV) types 1-11 were assigned to three serologic groups by indirect immunofluorescence (IIF). Serotype group I consists of PEV types 1-7 and 11 and is correlated with CPE-type I. Serotype group II is represented by PEV type 8, producing CPE-type II, while PEV types 9 and 10 are classified as serotype group III and cause CPE-type III. Three PEV isolates from the central nervous system of pigs with polioencephalomyelitis were assigned to serotype group I by IIF but to none of the established 11 serotypes by cross-neutralization. It is concluded that these isolates are representatives of two new PEV types for which the designation PEV12 and 13 is suggested.
