Over 2 million antibiotic-resistant infections occur annually in the U.S., highlighting the critical importance of understanding antibiotic limitations. When prescribing broad-spectrum cephalosporins, it's crucial for healthcare professionals and patients alike to know what bacteria do cephalosporins not cover to ensure effective treatment and avoid potential complications.

First introduced in 1961, ampicillin was a groundbreaking "broad-spectrum" penicillin effective against many Gram-negative and Gram-positive bacteria. This powerful antibiotic remains relevant for certain infections today, but its use is now guided by factors like bacterial susceptibility and resistance. So, what infections can ampicillin treat?

Listeriosis, a rare but serious foodborne illness, has a high hospitalization rate of over 90% and a case-fatality rate of 20–30% in invasive cases, making prompt and effective antibiotic treatment crucial for survival. The medication that kills *Listeria* depends on the severity and type of infection, but standard therapy typically involves ampicillin.
