^aData from the work of Soler-Bistué et al. (19).

^bThe fitness of V. cholerae derivatives was measured by pairwise competition. Results are shown as W_rel ± 95% confidence interval with respect to the parental strain. The percentage of μ variation with respect to the parental strain is included for comparative purposes.
