Antibiotic synergy testing for multidrug-resistant Gram-negative pathogens in a Greek ICU

The emergence of multidrug-resistant (MDR) pathogens is a major cause of infection-related mortality among critically ill patients. The synergistic effect between commonly used antibiotics against difficult to treat nosocomial MDR Gram-negative strains, if present, could provide a viable option as an alternative therapy. The aim of this study was to investigate the potential of antibiotic synergy against MDR A. baumannii, K. pneumonia and P. aeruginosa strains, isolated from critically ill patients in a Greek ICU.
