- Antibiotics are chemicals that kill bacteria.
What's really interesting about antibiotics
is most antibiotics get made by bacteria themselves.
So they're used by bacteria to fight with other bacteria
and kill them.
So almost all of the antibiotics
that a medical doctor would give you
were discovered from bacteria that are making them
either in the soil or in their natural environments.
Some of the antibiotic-resistant bacteria
are called superbugs.
They're called that in the news because they have resistance
to a bunch of different types of antibiotics.
- Whenever you add more and more antibiotic
to a person or the environment,
a bacteria can adapt and become resistant to it.
So we need to discover new antibiotics
to kind of overcome this adaptation
so they have something new to interact with.
