Escherichia coli with penicillin-binding protein 3 insertions: implications for newer β-lactam/β-lactamase inhibitor combinations
ABSTRACT Escherichia coli with penicillin-binding protein 3 (PBP3) insertions appeared in the early 2000s and expanded during the 2010s. The YRIN and YRIK variants predominate globally, while other insertion types remain rare. These insertions frequently co-occur with carbapenemases (NDM-5 and OXA-181) and high-risk cl...
