Penicillin-resistant Streptococcus pneumoniae (PRP) is of worldwide co
ncern. Treatment failures and fatalities of meningitis caused by PRP h
ave been reported in other locations but not yet in Israel. We describ
e an Ii-month-old infant with meningitis caused by PRP who failed to r
espond to initial treatment with cefotaxime. Vancomycin treatment caus
ed a prompt cure. The minimal inhibitory concentrations of the isolate
to penicillin, cefuroxime and cefotaxime were 1.0, 4.0 and 1.0 mu g/m
l, respectively. New guidelines for the treatment of meningitis in Isr
ael are suggested.
