Errors in gene expression enable survival of strains carrying a mutated antibiotic resistant gene. (A)
Strains PY79 (no cat), SB463 (cat), SB477 (catfs), and SB475 (catns) were grown on 4-µg/mL
chloramphenicol-containing plates. Plates were imaged after 40 h of incubation at 30 °C. (B) Strains PY79
(no cat), SB463 (cat), SB477 (catf), and SB475 (catns) were streaked on 10-µg/mL chloramphenicol-
containing plates and imaged after 40 h of incubation at 30 °C. (C) The viability (%) of SB477 (catfs) (red
bars) and SB475 (catns) (blue bars) at different temperatures when plated on chloramphenicol-containing
plates. Cells were grown in CH medium at the different temperatures in the absence of chloramphenicol,
and plated at mid-exponential phase on either LB or LB supplemented with 4-µg/mL chloramphenicol
plates. Percent-viability is the number of colonies growing on chloramphenicol-containing plates relative
to the total number of colonies growing on LB plates incubated at the equivalent temperature (Materials
and Methods). PY79 (no cat) strain did not grow on chloramphenicol-containing plates, whereas SB463
(cat) showed ~100% viability at any growth temperature. The viability on LB plates of all tested strains
was similar, with colony number ranging from 350 to 500.
