what is the difference between a narrow spectrum antibiotic and a broad spectrum antibiotic
Broad- and narrow-spectrum antibiotics: a different approach 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. Difference between a narrow spectrum and a broad spectrum antibiotic? A narrow-spectrum antibiotic acts only against specific families of bacteria. A broad-spectrum antibiotic acts against many different kinds of disease-causing bacteria, including both gram-positive and gram-negative bacteria. A narrow-spectrum antibiotic acts only against specific families of bacteria. Difference between a narrow spectrum and a broad spectrum antibiotic? Narrow spectrum antibiotics are only effective against a narrow group of bacteria. They include Vancomycin and Clindamycin. Broad spectrum antibiotics can tackle a wide ra â¦ nge of bacteria. They include Amoxicillin and Streptomycin.
