Does standard susceptibility testing overlook potent azithromycin activity and cationic peptide synergy against MDR Stenotrophomonas maltophilia?
Despite lack of activity in standard MIC testing, azithromycin synergizes with cationic peptide antibiotics to kill SM in medium mimicking tissue fluid conditions. Azithromycin, alone or in combination with colistin, merits further exploration in therapy of drug-resistant SM infections.
Our study revealed that CSC caused lung damage through the disruption of ER-Golgi homeostasis and autophagy induction. The expression level of the trans-Golgi marker protein GOLPH3 could serve as a reliable bio-indicator for CS-related lung cancer.
