Evaluation of the synergistic effect of a combination of colistin and tigecycline against multidrug-resistant Acinetobacter baumannii

ABSTRACT

Objective: Acinetobacter baumannii species cause nosocomial infections and can subsequently develop multidrug resistance [MDR]. The objective of this study was to evaluate the susceptibility of A. baumannii to a novel combination of colistin and tigecycline, which may provide a faster and more efficacious treatment via a synergistic effect
