Objective: The purpose of this study was to evaluate the susceptibility of extended-spectrum beta-lactamase (ESBL)-producing Enterobacteriaceae clinical isolates to ertapenem in a tertiary pediatric care center in Turkey.
Design/methods: All isolates of ESBL-producing Enterobacteriaceae were collected from clinical specimens from children, and susceptibility tests were done using the Vitek 2 compact system.
Results: Ninety-nine per cent of the ESBL-producing Escherichia coli isolates were found to be susceptible to ertapenem, 99.5% to imipenem and 100% to meropenem. In the Klebsiella species, 91.5% of the isolates were susceptible to ertapenem, 99.3% to imipenem and 100% to meropenem.
Conclusion: The results of our data, including isolates from children, showed that ertapenem had high in vitro activity against the majority of the ESBL-producing E. coli and Klebsiella species, as reported in previously published studies. However, additional clinical studies are required to assess the clinical activity of ertapenem and the clinical importance of the resistant isolates.
