Phylogenomics of the Vibrio cholerae O1 El Tor isolates from CAR, 1997–2016. A) Maximum-likelihood phylogeny for 1,215 7PET genomic sequences. A6 was used as an outgroup. The last 9 sublineages introduced into Africa (T5–T13) are indicated. On inner ring, color scale denotes geographic locations of the V. cholerae isolates. On outer ring, brown denotes isolates from CAR. Tree branches containing isolates from CAR are shown in red. Scale bar indicates substitutions per variable site. B) Locations on the African continent in which T7, T9, and T10 V. cholerae O1 serotype Inaba isolates were detected before their identification in CAR. CAR, Central African Republic.
