Which statement accurately reflects the scope of antibiotics?

Which statement accurately reflects the scope of antibiotics?

• A. They target bacteria, not viruses or fungi
• B. They cure viral infections
• C. They are effective against all pathogens including viruses
• D. They work equally well against fungi and viruses

Answer: (A)

Antibiotics work by exploiting features unique to bacteria, so their scope is limited to bacteria and does not extend to viruses or fungi. Bacteria have distinct targets such as the cell wall and 70S ribosomes or specific bacterial enzymes. These are essential for bacterial survival and are not present in viruses, which rely on host cells for replication, and not in fungi, which have different cellular structures and metabolic pathways. Because of these differences, antibiotics cannot eliminate viral infections, are not effective against all pathogens, and do not treat fungi with the same mechanisms. Therefore, the statement that best reflects the scope of antibiotics is that they target bacteria, not viruses or fungi.
