Amoxicillin, penicillin, and erythromycin are common antibiotics that inhibit bacterial cell functions. Antibiotics are derived primarily from bacteria or fungi (mold), such as Penicillium. Antibiotics don’t work exclusively against bacteria: some ‘broad-spectrum’ ones are also effective against protists.
