Fig 5. Phylogenetic analysis of partial pol gene sequences from all sites.
All group M virus sequences (47) from six sites were analyzed together with the EQAPOL reference sequences. The phylogenetic tree was constructed using the neighbor-joining (NJ) method with Kimura two-parameter model. Sequences from the USA_FDA site were not included due to divergent sequence fragments. Ambiguous bases in DEURF07ES002 (*) and DEURF07BR002 (#) from Canada and Brazil sites resulted in independent branches. The short sequences (⌘) of DEMD07UG002 and DEURF10US008 from the Malaysia site were excluded from the analysis.
