Predictive Information for Streptococcus pneumoniae Susceptibility Tests

Penicillin susceptibility data may be used to predict susceptibility to the following antimicrobials:

For NON-MENINGEAL pneumococcal isolates, penicillin susceptible by screen or penicillin MICs of <=0.06 predict susceptibility to: ampicillin (oral or parenteral), ampicillin-sulbactam, amoxicillin, amoxicillin-clavulanic acid, cefaclor, cefdinir,cefditoren, cefepime, cefotaxime, cefpodoxime, cefprozil,  ceftaroline, ceftizoxime, cefuroxime, doripenem, ertapenem, imipenem, loracarbef and meropenem.
