and I did my graduate work at the University of Washington in Seattle.

And I'm going to tell you today about work I did in graduate school

studying how bacteria interact with one another

and how they survive out in the environment

So, I'm going to start out by telling you that

I was looking at one of those little yogurt containers

where it says, "Contains live and active cultures,"

and I wondered whether that was really true.

and I went and looked at it under the microscope.

-- there's long rods, there's short rods,

had slightly different bacterial groups in them

so this was really my first exciting glimpse

and they make delicious things for us to eat.

So this got me really excited about the idea of

studying how bacteria live in these communities together.

So, of course, bacteria are not just in our yogurt;

accidentally swallow a little ocean water.

That's a lot of bacteria that you've just taken into your body.

and of course there's bacteria in our bodies,

in our guts there's billions of bacteria,

there's bacteria in our mouths and our skin,

and they help our immune systems work properly as well.

and that's actually usually what we've been studying them for

So, the organism that I'm going to tell you about today

is this organism called Pseudomonas aeruginosa.

actually mostly found out in the environment.

It lives in the soil, it lives in the water,

and we come into contact with it all the time.

So, mostly, it doesn't really cause us a lot of problems...

but occasionally Pseudomonas can get into

and it plays a really important role in the ecosystem,

but if a termite gets into someone's home,

You know, mostly we don't worry about it,

but if Pseudomonas gets into the wrong human environment,

A lot of might have loved ones, family members,

prone to getting bedsores or chronic wounds.

These are also common in people with type II diabetes.

And these are wounds that just cannot heal;

So, especially if Pseudomonas gets in there,

it can be really, really bad for these people.
