Only one species of bacteria is affected by a single antibiotic.

|
|
Only some types of virus and bacteria are affected by antibiotics, because of the evolution of resistance.

Detailed explanation-1: -Viruses don’t have cell walls that can be attacked by antibiotics; instead they are surrounded by a protective protein coat. Unlike bacteria, which attack your body’s cells from the outside, viruses actually move into, live in and make copies of themselves in your body’s cells.
Detailed explanation-2: -Antimicrobial resistance is accelerated when the presence of antibiotics and antifungals pressure bacteria and fungi to adapt. Antibiotics and antifungals kill some germs that cause infections, but they also kill helpful germs that protect our body from infection. The antimicrobial-resistant germs survive and multiply.
Detailed explanation-3: -Antibiotic resistance occurs when bacteria change in response to the use of these medicines. Bacteria, not humans or animals, become antibiotic-resistant. These bacteria may infect humans and animals, and the infections they cause are harder to treat than those caused by non-resistant bacteria.
Detailed explanation-4: -Overuse of antibiotics is creating stronger germs. Some bacteria are already “resistant” to common antibiotics. When bacteria become resistant to antibiotics, it is often harder and more expensive to treat the infection. Losing the ability to treat serious bacterial infections is a major threat to public health.
