Even when the broad-spectrum drug is capable of killing a target pathogen, it may not be the best treatment. Which statement best explains why a broad spectrum drug might be an undesirable treatment choice? Broad-spectrum antimicrobials are usually toxic to the host cells. Broad-spectrum antimicrobials only work if they are used shortly after the infection begins. Broad-spectrum antimicrobials may kill much of the normal microbiota. Broad-spectrum antimicrobials are not able to kill bacteria that are in their log phase of growth.
