Temporal patterns of resistance to selected antimicrobial agents for a)
, and e)
. Antimicrobial resistance rates were analyzed yearly for E. coli and K. pneumoniae, and combined into two time groups of 2002–06 and 2007–11 for K. oxytoca, E. cloacae, and P. aeruginosa due to lower isolate numbers. Number of isolates for each GNB is listed below the corresponding year or time groups. Y-axis represents resistance in percentage. Note: Pip-tazo is piperacillin-tazobactam, TMP-SMX is trimethoprim-sulfamethoxazole, Tic-clav is ticarcillin-clavulanate.
