FIG 4.
Antibiotic susceptibility of E. coli porin mutants under high-salt conditions. (A) Growth rates of E. coli wild-type (WT), ompC-deficient, and ompF-deficient strains upon tetracycline (Tet) treatment in glucose medium containing 0.1 or 0.4 M NaCl. (B) Growth rates of E. coli wild type, ompC-deficient, and ompF-deficient strains upon chloramphenicol (Cm) treatment in glucose medium containing 0.1 or 0.4 M NaCl.
