Genomic comparison among Elizabethkingia species. The genome of E. anophelis 296-96 (center) compared to E. anophelis 344-1 (the innermost circle; ring 1), outbreak strains, including 15 E. anophelis isolates (ring 2), non-outbreak strains, including E. anophelis 277-17 (ring 3) and E. anophelis 313-22 (ring 4), environmental strains, including E. anophelis 2–62 (ring 5) E. anophelis 2–8 (ring 6) and E. anophelis 2–14 (ring 7). Seven genomic regions (GRs) were identified different between outbreak and non-outbreak strains. GR1 and GR6 were type III and type I integrative and conjugative elements (ICEs), respectively.
