Which term describes a drug that fights infection?

• A. Anuria
• B. Antibiotic
• C. Antepartum
• D. Antidiuretic

Answer: (B)

A drug that fights infection is called an antibiotic. The prefix anti- means against and bio or biotic relates to life forms, so an antibiotic acts against bacteria to stop their growth or kill them. Antibiotics target bacterial processes such as cell wall synthesis, protein production, or DNA replication, which is why they’re effective for bacterial infections but not viral ones. It’s important to use them appropriately to avoid resistance. Other terms here describe things unrelated to fighting infections: anuria means absence of urine production, antepartum refers to the period before birth, and antidiuretic describes a substance that reduces urine output.
