Acinetobacter baumannii is an opportunistic bacterial pathogen capable of causing a variety of infections, including pneumonia, sepsis, wound, and burn infections. A. baumannii is an increasing threat to public health due to the prevalence of multidrug-resistant strains, leading the World Health Organization to declare A. baumannii a “Priority 1: Critical” pathogen, for which the development of novel antimicrobials is desperately needed.
