I. Antibiotics interrupt processes found in some but not all pathogen cells. For instance, some antibiotics are directed to cell walls that not all bacteria posses.

II. Some pathogens have no metabolic processes to interrupt. The antibiotics that are directed to metabolic reactions of bacteria are not effective in treating viruses because they do not perform this metabolic reactions.

III. Some pathogens have developed genetic resistance to specific antibiotics. Bacteria have a remarkable genetic plasticity having plasmids that can be easily transmitted among them, which give them antibiotic resistance.
