In the wake of emerging antimicrobial resistance, antibacterial drug development has become more critical. At the same time, development of antibacterial drugs targeting specific pathogens or resistance phenotypes that may have low prevalence presents challenges because it is difficult to conduct large, randomized controlled trials for such drugs. Animal models have increasingly supported clinical development of antibacterials; however, more work is needed to optimize the design and application of these animal models to ensure clear and actionable translation to further human investigation. This review discusses recent case studies of animal infection models used to support antibacterial drug development in order to illuminate considerations for future development of novel antibacterial drugs.
