*Carbapenem-resistant Enterobacteriaceae were resistant to imipenem, meropenem, doripenem, or ertapenem. Enterobacteriaceae resistant to ceftriaxone, ceftazidime, cefepime, or cefotaxime were cephalosporin resistant. The percentage of resistant Enterobacteriaceae is not shown when <30 Enterobacteriaceae are reported within a county. NS, not shown; % R, percentage resistant.
†The number and percentage of Enterobacteriaceae with reported antimicrobial susceptibility test results as a proportion of the overall number reported (i.e., with or without antimicrobial susceptibility test results).
1Preliminary data from this analysis were presented in a poster at IDWeek 2018 in San Francisco, California, USA, October 5, 2018.
