Did you know that everywhere around you, there are tiny microscopic organisms? It's true! They're in the water, in the air, and they're even inside you. Don't worry, most of them are not bad for you, but some of them are, and those are the ones that cause infectious diseases. In this playlist we will go over some fundamental concepts in microbiology, and then focus largely on going through these infectious diseases one at a time, so we can learn about the pathogens that cause them, how their virulence operates, and how we can treat them!
