Abstract Background Chlorhexidine is a widely used disinfectant in clinical settings and broad-spectrum antimicrobial agent effective against aerobic anaerobic bacteria. However, resistant or non-susceptible bacteria, including antibiotic-resistant Acinetobacter baumannii, have been found. This study aimed to develop new technique prevent control A. baumannii infection the hospital setting. Met...

Colistin is highly promising against multidrug-resistant and extensively drug-resistant bacteria clinically. Bacteria are resistant to colistin mainly through mcr chromosome-mediated lipopolysaccharide (LPS) synthesis-related locus variation. However, the current understanding cannot fully explain resistance mechanism in -negative colistin-resistant strains. Significantly, contribution of efflu...
