First and foremost: antibiotics are neato!
Most of us are pretty familiar with antibiotics.
If you want a brief (yet still long...) history of their awesomeness, I recommend clicking here.
One of the most common antibiotics is penicillin:
Penicillin (and other antibiotics) are awesome drugs that fight off bacterial infections.
Antibiotics work by destroying a bacterium's cell wall or by outright killing the bacteria.
...but a problem we're facing today is that some antibiotics are losing their effectiveness.
Bacteria growing resistant to antibiotics is an expected event, but the rate at which it is happening could be slowed down considerably.
There are several causes of antibiotic resistance, but two significant causes of antibiotic resistance are over prescription and improper use,
...because when you unnecessarily take antibiotics or fail to stay on a full course of medicine, this happens:
...and bacteria that aren't fully killed off can morph and become antibiotic resistant.
...which has contributed to the rise of unpleasant and scary things like superbugs.
So please, do your part in preserving the neato-ness that are antibiotics.
