INTRODUCTION Acinetobacter baumannii has attained an alarming level of resistance to antibacterial drugs. Clinicians are now considering the use of older agents or unorthodox combinations of licensed drugs against multidrug-resistant strains to bridge the current treatment gap. We investigated the in vitro activities of combination treatments that included colistin with vancomycin, norvancomyci...
Nowadays antibiotics are broadly used not only for treatment of bacterial infections but also in nonmedical applications. For many years they have been added as livestock and poultry growth supplements, and they are applied similarly in fish farming. In basically unchanged form they may get into the natural environment and remain there for a long time. Excessive use of antibiotics leads to wide...
It has been widely assumed that the ecological function of antibiotics in nature is fighting against competitors. This made them a good example of the Darwinian struggle-for-life in the microbial world. Based on this idea, it also has been believed that antibiotics, even at subinhibitory concentrations, reduce virulence of bacterial pathogens. Herein, using a combination of genomic and function...
