To slow the rate of developing antibiotic resistance in bacteria, physicians are being encouraged to use "narrow-spectrum" antibiotics- those that target only a few bacterial types. How can the information learned by antibiotic sensitivity testing be used by physicians who must choose antibiotics that inhibit the growth of bacteria causing disease but that do not interfere with beneficial bacteria?
