Figure 7From: Tobramycin at subinhibitory concentration inhibits the RhlI/R quorum sensing system in a Pseudomonas aeruginosaenvironmental isolate Swarming of P. aeruginosa PUPa3 on 0.5% LB agar plates at 37°C after 24 hrs. In the presence of SIC tobramycin (0.05 μg/mL) no swarming is present in WT (B), but the swarming was restored with the expression of RmtA (C), RmtC (D) or NpmA (E) methyltransferases as in LB plates inoculated with WT (A).Back to article page
