Figure 5.
In vitro growth of mutants with transposon insertions in sick genes. (A) Culture density (OD 600) of wild-type V. cholerae and mutants with transposon insertions in ‘sick’ gene candidates is plotted as a function of time. (B) Competitive indices from in vitro competition assays between wild-type V. cholerae and mutants with insertions in candidate ‘sick’ genes are shown. Competitive indices were calculated as the ratios of mutant and wild-type CFUs after overnight co-culture in LB. *P < 0.001.
