The name shares the same stem with<unk> al evidence, involving an idea of practical experience.<unk>  antimicrobial therapy is directed against an anticipated and likely cause of infectious disease. It is used when antimicrobials are given to a person before the specific bacterium or fungus causing an infection is known. When it becomes known, treatment that is used is called directed therapy. Fighting an infection sooner rather than later is important to minimize morbidity, risk, and complications for serious infections like sepsis and suspected bacterial meningitis.
