High genetic diversity of porcine enterovirus G in Schleswig-Holstein, Germany.

Between 2012 and 2015, 495 pooled snout swabs from fattening pigs raised in Schleswig-Holstein, Germany, were screened for the presence of enterovirus G (EV-G) RNA. Nucleic acids were tested in diverse reverse transcription polymerase chain reaction assays applying published oligonucleotide primers specific for the viral protein (VP) 1 and 2/4 encoding regions as well as for 3D polymerase. Phylogenetic analyses of VP1 revealed the presence of 12 EV-G types, three of which had highly divergent sequences suggesting putative new types. Co-circulation of EV-G types was observed in several pigsties. Thus, genetic diversity of EV-G was demonstrated in this small geographic area.
