Abstract
The Meropenem Yearly Susceptibility Test Information Collection (MYSTIC) Program provides antimicrobial susceptibility data. The activity of meropenem and 7 broad-spectrum antimicrobials have been examined against 12 645 bacterial isolates from 14 European centers between 1997 and 2002. Cumulative susceptibility rates against all species of Enterobacteriaceae combined were ranked as follows: meropenem (99.9%) > imipenem (97.7%) > ciprofloxacin (86.0%) > piperacillin-tazobactam (85.6%) > ceftazidime (85.4%) > gentamicin (85.4%) > tobramycin (85.0%) > cefotaxime (83.8%). The carbapenems were also found to be the most active of the classes tested against nonfermentative Gram-negative bacilli. Against methicillin-susceptible Staphylococcus aureus and coagulase-negative staphylococci, all β-lactams tested (except ceftazidime) had susceptibility rates of â¥99.0% and â¥94.3%, respectively. Over the 6-year period, there was no loss of activity or increase in resistance rate for either carbapenem against any of the species tested. These data confirm the continued potency and broad-spectrum activity of meropenem in units where it is actively being prescribed.
