Can overuse of antibiotics cause bacterial resistance?

Posted on August 28, 2022 by Author

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. Some bacteria are now resistant to even the most powerful antibiotics available.

Why should humans be concerned that bacteria are becoming antibiotic resistant?

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. Antibiotic resistance leads to higher medical costs, prolonged hospital stays, and increased mortality.

What happens when you take too many antibiotics?

Bacteria and fungi naturally use antibiotics as weapons to kill each other to compete for space and food; they have been doing this for over a billion years.

Can antibiotic resistant bacteria be transmitted from person to person?

Antibiotic resistant bacteria can also be passed from person to person within the community. This is becoming more common. Ways to prevent transmission of organisms, including antibiotic resistant bacteria, are: Wash hands before and after food handling, going to the toilet and changing nappies.
