Fig. 7. Inhibition of P.aeruginosa QS in mouse lungs. Photomicrographs of mouse lung tissue infected with P.aeruginosa carrying the dual-labeled PA quorum sensor for detection of QS signaling and a red fluorescent tag for simple identification in tissue samples. Mice were administered C-30 via intravenous injection at time zero. Infected animals were killed in groups of three at the time points indicated and the lung tissue samples were examined by SCLM.
