FIG 3.

Maximum parsimony tree based on partial VP1 genes (25) of EV-A (upper left), EV-B (right), and EV-C (lower left) typed in the environmental enterovirus surveillance (EEVS) in the Dutch Bible Belt (September 2005 to February 2015, blue circles), Ter Apel (November 2013 to February 2015, red circles), and the clinical enterovirus surveillance (CEVS) (January 2007 to February 2015, green circles). Note that sequences were omitted from analysis when sequence length was too short (<250 nucleotides) or only partially overlapping within the fragment length defined by the primers used (25).
