Figure 1: Distribution of multilocus sequence types for 410 isolates from the USA in 2017.
The 22 most numerous sequence types, which include five or more isolates, are shown according to susceptibility to azithromycin, ceftriaxone, and cefixime. Decreased susceptibility to azithromycin is defined as MIC ≥2 μg/mL. Decreased susceptibility to cefixime is defined as MIC ≥0·250 μg/mL. Decreased susceptibility to ceftriaxone is defined as MIC ≥0·125 μg/mL. MIC=minimum inhibitory concentration.
