Figure 26. Gonococcal Isolate Surveillance Project (GISP) — Percent of Neisseria gonorrhoeae isolates with resistance or intermediate resistance to ciprofloxacin, 1990–2007

Note: Resistant isolates have ciprofloxacin MICs ≥ 1 μg/ml. Isolates with intermediate resistance have ciprofloxacin MICs of 0.125 – 0.5 μg/ml. Susceptibility to ciprofloxacin was first measured in GISP in 1990.
