Figure 32. Susceptibility Patterns of Neisseria gonorrhoeae Isolates to Antimicrobials, Gonococcal Isolate Surveillance Project (GISP), 2017

Figure 32. Pie chart showing susceptibility patterns of Neisseria gonorrhoeae isolates to different antimicrobials in 2017. Data from the Gonococcal Isolate Surveillance Project.

* Susceptible category only includes isolates with penicillin, tetracycline, and fluoroquinolone MIC values that are considered susceptible and isolates with ceftriaxone, cefixime, and azithromycin MIC values that are not considered elevated.

NOTE: Elevated MIC = Ceftriaxone: ≥0.125 μg/ml; Cefixime: ≥0.25 μg/ml; Azithromycin: ≥2.0 μg/ml. Resistant (R) MIC = Tetracycline: ≥2.0 μg/ml; Fluoroquinolone: ≥1.0 μg/ml; Penicillin: ≥2.0 μg/ml or PPNG.

ACRONYMS: R = Resistant; PPNG = Penicillinase-producing Neisseria gonorrhoeae and chromosomally-mediated penicillin-resistant N. gonorrhoeae; MIC = Minimum Inhibitory Concentration.
