Proportion of Neisseria gonorrhoeae isolates with different minimum inhibitory concentrations (mg/L) for (A) ceftriaxone (n = 1,982 isolates), (B) cefixime (n = 1,985 isolates) and (C) azithromycin (n = 1,981 isolates), by year, Barcelona, Spain, 2013−2017

EUCAST: European Committee on Antimicrobial Susceptibility Testing; MIC: minimum inhibitory concentration.

According to EUCAST, the MIC breakpoints for resistance to ceftriaxone and cefixime are identical and are MIC > 0.125 mg/L. The epidemiological cut-off for azithromycin is > 1mg/L.
