Abstract
A case of a 5-year-old child with signs and symptoms of bacterial meningitis was admitted
to the “Iatrikon Athinon” Medical Center, Athens, Greece. The isolated strain was
identified as Neisseria lactamica. Susceptibility to penicillin, cefotaxime, ceftriaxone, tetracycline, sulfonamides,
rifampicin, ciprofloxacin, erythromycin and chloramphenicol was determined twice by
E-test. The isolate was resistant to penicillin (8 μg/mL) and erythromycin (64 μg/mL).
Since antibiotic susceptibility testing revealed that the isolate was resistant to
penicillin, the patient was successfully treated with ceftriaxone. This is a first
report of a meningitis case due to penicillin-resistant N. lactamica in Greece.
