Hello. My name is Dave Westenberg.
I'm an Associate Professor of
Biological Sciences at Missouri University of Science and Technology.
I'm here to give you an introduction to the world of microbes.
So, here's a little road map of where I'm going to take you today.
First of all, we will go through a little bit about what is a microbe
and tell you a little about the history of microbiology as a scientific discipline,
but also maybe a little bit of pre-history.
We'll talk about how we see microbes,
because that's certainly a big part of how
microbes were discovered and how we work with them.
I'll, then, take you a little bit through how we described microbes,
the different ways that we can define them and tell us what they are.
Then, I'll talk a little bit about their importance,
how they impact our health,
and how they impact our earth through our environment.
Then, I'll talk a little bit about how we use microorganisms today,
now that we've had the power to capture what they can do.
So, what is a microbe?
To kick things off here,
I'll tell you a little bit about what I'm talking about here.
Microbes are organisms for which you need a microscope to see.
So, that may make sense now when you think about that name and the word microscope.
The kinds of organisms that we're talking about here are bacteria,
archaea, fungi, protists, and viruses.
So, we're going to take you a little bit through the world of these microscopic organisms.
