Figure 3. Effect of lsr2 Inactivation and Overexpression on Antibiotic Susceptibility in M. smegmatis .
(A and B) Antibiotic susceptibility is calculated by examining the proportion of colonies surviving on plates containing (A) EMB or (B) ciprofloxacin (CIP) compared to plates without antibiotics.
▴, the Mc2155 NJS20 control; ▪, the NJS20.1 lsr2 transposon mutant; ⋄, the NJS20.1c complemented strain. The mean and standard deviations of at least triplicate cultures of each strain are shown.
