"antibiotic" の定義と意味

What is an "antibiotic"?

An antibiotic is a type of medication used to treat bacterial infections by either killing bacteria or stopping their growth. Antibiotics work by targeting specific bacterial processes or structures essential for their survival, which are different from bacterial processes or structures found in human cells. They are prescribed to fight various bacterial infections such as urinary tract infections, skin infections, respiratory infections like pneumonia, and infections of the ear, throat, or sinuses.
