Which of the following pathogen types cause diseases that can be treated with antibiotics? (A) Bacteria (B) Macro-parasites (C) Prions (D) Viruses - HSC - SSCE Biology - Question 2 - 2008 - Paper 1

Antibiotics are effective against bacterial infections. Therefore, the correct answer is (A) Bacteria.

• Bacteria: These are single-celled organisms that can reproduce independently and are known to cause various diseases such as strep throat and tuberculosis, which can be treated with antibiotics.
• Macro-parasites: These include larger organisms such as worms and are not affected by antibiotics.
• Prions: These are misfolded proteins that cause neurodegenerative diseases and cannot be treated with antibiotics.
• Viruses: These are smaller than bacteria and cannot be treated with antibiotics; instead, antiviral medications are needed.
