Why are some antibiotics no longer effective in killing pathogens?

Why are some antibiotics no longer effective in killing pathogens?

Antibiotics have been used for a long time and are frequently prescribed. Because of this widespread use, the infectious bacteria the antibiotics were designed target have adapted and changed, making the drugs less effective. This is antibiotic resistance.

Why are antibiotics so dangerous?

Taking antibiotics for colds and other viral illnesses doesn’t work — and it can create bacteria that are harder to kill. Taking antibiotics too often or for the wrong reasons can change bacteria so much that antibiotics don’t work against them. This is called bacterial resistance or antibiotic resistance.

They have made a major contribution to human health. Many diseases that once killed people can now be treated effectively with antibiotics. However, some bacteria have become resistant to commonly used antibiotics. Antibiotic resistant bacteria are bacteria that are not controlled or killed by antibiotics.
