Identification of group I porcine enteroviruses by monoclonal antibodies in cell culture

A panel of monoclonal antibodies (mAb) against porcine enteroviruses (PEV) was established. One of these mAbs reacts group-specifically with PEV of serotype group I in the indirect immunofluorescence assay (IIF). This mAb is very well suited for diagnosis of PEV infections. However, the mAb neither neutralizes virus nor does it react with virus particles in immune electron microscopy (IEM). Another mAb is PEV-1 specific in IIF, neutralizes virus, and is suited for IEM. Both mAbs presumably recognize conformation-dependent epitopes of the virus.
