Zusammenfassung:of treating Gram-negative bacteria that also exhibit resistance to the anti-bacterial compound colistin (MIC≥50 mg/mL) except for Burkholderia, Proteus, and Serratia that comprises contacting the bacteria with an aqueous pharmaceutical composition containing a rose bengal (RB) compound of Formula I, below, dissolved or dispersed therein at a concentration of about 0.01 to about 15 mg/mL and irradiating those contacted bacteria with light of the wavelength about 500 nm to about 600 nm for a time period of about 1 to about 10 minutes to provide a light dose of about 16 to about 160 J/cm2, treat and kill the irradiated bacteriawherein X, R1, R2 and M+ are defined within.
