FIG 1.

MIC distributions of fosfomycin (FOS) obtained using the Etest on GC agar (MICs were adjusted to the whole MIC doubling concentrations, e.g., from 12 to 16 μg/ml). Eighty-nine clinical isolates (of which 10 had an MDR phenotype) were evaluated. Notably, the MICs of the three control strains (F89, AZT-HLR, and ATCC 49226) were not included in the distribution. According to the CLSI or the EUCAST criteria set for Enterobacteriaceae (26, 27), all N. gonorrhoeae isolates were susceptible (S) to FOS in vitro.
