Gram negative bacilli are often treated with O penicillin G. O vancomycin. aminoglycosides. synercid. isoniazid. The drug used for several protozoan infections is O nystatin. O griseofulvin. amphotericin B. O sulfa drugs. O metronidazole. Antimicrobics effective against a wide variety of microbial types are termed antibiotics. narrow-spectrum drugs. semisynthetic drugs. synthetic drugs. broad-spectrum drugs. A"shotgun" approach to antimicrobial therapy involves giving a narrow spectrum drug culturing the pathogen and identifying it. performing the disk diffusion assay. O using a broad spectrum drug so that the chance of killing the pathogen is greater. using antiviral and antibiotic drugs in combination. All of the following could be reasons why antirnicrobic treatment fails except the inability of the drug to diffuse into the infected body compartment. a mixed infection where some of the pathogens are drug resistant not completing the full course of treatment. a disk diffusion test showing pathogen sensitivity to the antimicrobic.
