Why antibiotics don't damage eukaryotic cell or viruses?

Antibiotics primarily target specific bacterial structures or functions, such as cell wall synthesis, protein synthesis, or DNA replication, which are absent in eukaryotic cells. Eukaryotic cells have different ribosomal structures and metabolic pathways that are not affected by the mechanisms of action of antibiotics. Additionally, viruses lack cellular structures and metabolic processes altogether, making them immune to antibiotics, which are designed to target living cells. Thus, antibiotics are effective against bacteria but do not harm eukaryotic cells or viruses.
