“This is an exciting and unexpected discovery that questions the standard paradigm in the field,” Kim Lewis, director of the Antimicrobial Discovery Center at Northeastern University not involved with the study, told Tech Insider.
To understand how mutations in many different genes affect the “fitness,” or ability to survive in and make a host sick, the team infected mice with various strains of Pseudomonas aeruginosa, a particularly nasty bacteria that infects the nose, throat, lungs, and can lead to pneumonia and blood infections. Without treating the mice with any medications, they found that the mice infected with antibiotic-resistant strains of the bacteria were more likely to die than those infected with bacteria that were not resistant.
