Susceptibility testing challenges with ceftaroline, MRSA and a 1 mg/L breakpoint.


OBJECTIVES A 1 mg/L susceptibility breakpoint for ceftaroline and staphylococci is universally agreed; EUCAST counts MIC >1 mg/L as resistant whereas CLSI and FDA count 2 mg/L as intermediate and >2 mg/L as resistant. We investigated whether routine diagnostic tests reliably distinguish MICs of 1 versus 2 mg/L. METHODS Thirty-five UK laboratories… (More)
