Gonococcal Susceptibility to Cephalosporins—Hawaii, 2003 to 2011

Among gonococcal isolates examined at the Hawaii State Laboratory Division from 2003 to 2011, the prevalence of elevated cefixime minimum inhibitory concentrations (MICs; ≥0.064 μg/mL) and elevated cefpodoxime MICs (≥0.19 μg/mL) increased over time. In contrast, few isolates exhibited elevated ceftriaxone MICs (≥0.094 μg/mL), and the prevalence of elevated ceftriaxone MICs did not change.

Below:  Proportion of gonococcal isolates with an elevated cefixime MIC (MIC ≥0.064 μg/mL) and elevated cefpodoxime MIC (MIC ≥0.19 μg/mL)—HGCSP, 2003 to 2011. *There was no cefixime testing, July 2004 to December 2009; testing for cefpodoxime started in April 2004.
