Abstract
BACKGROUND:
Infections caused by antibiotics-resistant Gram-positive bacteria have been reported from many pediatric hematology-oncology centers.
METHODS:
The susceptibility profiles to meropenem, piperacillin, and vancomycin among oral flora isolates of alpha-hemolytic streptococci (AHS) obtained from six children with cancer who received several empirical therapies (ET) against febrile neutropenia, were investigated.
RESULTS:
Meropenem minimum inhibitory concentration (MIC) of AHS isolated from ET patients was 2.167 +/- 0.258 microg/mL (mean +/- SD), which was significantly higher than the MIC of AHS isolated from control groups. Intriguingly, AHS isolated approximately 6 months after hospital discharge indicated recovery of susceptibility to meropenem.
CONCLUSIONS:
AHS isolates from neutropenic children with cancer should be checked for antibiotic susceptibility, even against carbapenems.
