Antibiotics are used to combat what type of infections?

• A. Helminths
• B. Bacterial
• C. Prions
• D. All of the above

Answer: (B)

Antibiotics are medications that specifically target bacteria, not viruses, parasites, or prions. They work by disrupting bacterial processes such as cell wall synthesis, protein production, or DNA replication, which are distinct from the biology of helminths, prions, or viruses. Because of that, antibiotics are used to treat bacterial infections. Infections caused by helminths require antihelminthics, prion-related diseases aren’t treated with antibiotics, and viruses require antiviral therapies. The choice that lumps all types together isn’t correct because antibiotics don’t address viral, prion, or parasitic infections.
