The phylogenetic tree constructed by core-genome multilocus sequence typing (cg-MLST) between 41 completed genomes (including 22 genomes in our study) and 45 draft genomes of Elizabethkingia anophelis. The 18 strains in the dominant lineage, E. anophelis 277-17, and SUE were in the same clade (rectangle). *, four strains not belonging to the dominant lineage according to PFGE analysis in our study, including E. anophelis 277-17, 313-22, 2-8, and 2–14.
