| Vibrio cholerae YB4B03 (CC 2) | 4 | 2 |
| Vibrio cholerae YB7A06 (CC 4) | 2 | 1 |
| Vibrio cholerae YB3B05 (CC 1) | 1 | 0 |

Note.—Only one strain from each clonal complex (CC) was included. An HGT event was hypothesized when a strain clustered with members of the other species in a phylogenetic tree, with reliable bootstrap support (>70%). Unequal variance t-test, P = 0.0012.
