Question

Quizplus · Accepted Answer

Small-spectrum drugs are effective against only a few types of bacteria, while narrow-spectrum drugs are effective against only one specific group of bacteria. Broad-spectrum drugs are effective against both gram-positive and gram-negative bacteria, as well as several other types of microorganisms. Therefore, the best choice for drugs that are effective against both gram-positive and gram-negative bacteria but not all of them is medium-spectrum drugs. These drugs have a broader range of activity than narrow-spectrum drugs but are more focused than broad-spectrum drugs.
