Pesticide/Antibiotic Resistance
Pesticide- a chemical that is used to kill insects
Antibiotic- a drug used to destroy bacteria.

When an anitbiotic or a pesticide is over-used, then the organism may become resistant and develop super-bacteria. The bacteria can then fight off the anitibiotics, or the pesiticides in insects, and they are therefore useless. This results in insects that cannot be killed by pesticides and bacteria that are resistant to antibiotics.

This is an example of super-bacteria from a blog.













Super bacteria are bacteria that have genes that enable them to fight against the antibiotic and they eventually spread these genes when they reproduce. Many different structures in bacteria are used to resist antibiotics.

Insects are very similar in this way, in that they also become resistant to the thing that is supposed to kill them. The insects possessing the genes that are used to fight off the pesticides then pass on their genes to future generations and this results in an essentially immortal family of bugs.

The use of antibiotics to cure infections is becoming more and more prevalent. This is causing many diseases to become less and less curable.


Example: The Mycobacterium tuberculosis (which causes tuberculosis) has become more resistant and tuberculosis is harder to cure to those who are resistant.
