Subinhibitory concentrations of polymyxin B nonapeptide sensitized all 21 polymyxin-susceptible gram-negative bacterial strains studied to hydrophobic antibiotics such as fusidic acid, novobiocin, and erythromycin. The susceptibility increases were usually 30- to 300-fold. The strains included representatives of Escherichia coli with different O- and K… CONTINUE READING
