|
|
Viruses are not affected because they have no metabolism, and some bacteria have evolved resistance.
|
|
|
Bacteria are not affected by antibiotics, only viruses.
|
|
|
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 and bacteria also have a different structure and a different way of surviving. Viruses are surrounded by a protective protein coating; they don’t have cell walls that can be attacked by antibiotics like bacteria does. It is because of this that antibiotics don’t work on viruses.
Detailed explanation-2: -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-3: -Since bacteria are extremely numerous, random mutation of bacterial DNA generates a wide variety of genetic changes. Through mutation and selection, bacteria can develop defense mechanisms against antibiotics.
Detailed explanation-4: -To survive, germs can develop defense strategies against antibiotics and antifungals called resistance mechanisms. DNA tells the germ how to make specific proteins, which determine the germ’s resistance mechanisms. Bacteria and fungi can carry genes for many types of resistance.
