The term broad-spectrum antibiotic refers to an antibiotic that acts against a wide range of disease-causing bacteria. A broad-spectrum antibiotic acts against both Gram-positive and Gram-negative bacteria, in contrast to a narrow-spectrum antibiotic, which is effective against specific families of bacteria. An example of a commonly used broad-spectrum antibiotic is ampicillin.
We should only use agents that are active against potential pathogens whilst sparing indigenous physiologic flora. This sort of antibiotic is a narrow-spectrum antibiotic by current definition, only active against potential pathogens. Broad-spectrum antibiotics kill both potential pathogens and also the normal flora. Flucloxacillin is broader than cephradine, from an ecological point of view [13,14]. In addition to exerting a selection pressure on MRSA, flucloxacillin may promote concomitant overgrowth of MRSA and encourage dissemination.
