GC genetic marker association with AZI MICs. A previously sequenced convenience sample of 732 GISP isolates from 2013 – 2015 underwent genetic marker analysis at CDC. Analyses of the 23S rRNA C2611T (A) and A2059G (B) mutations are shown. The wild-type base at position 2611 is C, and is A at position 2059. The circle at ≥16 μg/ml highlights the three isolates with the A2059G mutation.
