And, welcome back.
00:02
As we go through these series of talks relating host and pathogen interactions,
we need to talk about the different classes of microorganisms so we can give you an overview.
00:14
Again, there is a whole entity of study in biology called microbiology,
where you learn about all of these stuff in excruciating detail,
and you know, what sugars a bacteria ferments and what pH it likes to live at,
we're not going to do that.
00:29
But we are going to give kind of a broad overview of the different bugs
that can be encountered in the human body,
and then how they would present in terms of the host reaction.
00:41
Here's our roadmap.
00:44
So we already talked about the fundamental concepts of microorganisms including tropisms.
00:48
Now we're going to overview the different classes.
00:51
So, you can probably run down this as quickly as I can,
but we have viruses, we have bacteria, we have fungi, protozoans, worms, prions.
01:04
And given the vast variety of these particular pathogens that are out there,
it's remarkable that we aren't constantly being infected.
01:12
It just goes to show you how good the immune system is in protecting us.
01:16
Alright, so let's go through these each in turn.
