In Vivo Evolution of CTX-M-215, a Novel Narrow-Spectrum β-Lactamase in an Escherichia coli Clinical Isolate Conferring Resistance to Mecillinam

Here, we report a novel narrow-spectrum β-lactamase CTX-M-215 identified in an Escherichia coli clinical isolate in China and conferring high-level resistance to mecillinam but not to cefotaxime. CTX-M-215 differed from CTX-M-125, a CTX-M extended-spectrum β-lactamase (ESBL), by an N132D substitutio...
