FIG 1

A high salt concentration cross-protects E. coli from antibiotic treatment. (A) Growth rate of E. coli upon tetracycline (Tet) treatment in glucose medium containing 0.1 or 0.4 M NaCl. (B) Relative change in the growth rate upon tetracycline treatment. λ0 denotes the growth rate of E. coli in drug-free medium. (C) Growth rate of E. coli upon chloramphenicol (Cm) treatment in glucose medium containing 0.1 or 0.4 M NaCl. (D) Relative change in the growth rate upon chloramphenicol treatment. λ0 denotes the growth rate of E. coli in drug-free medium. WT, wild type.
