Microbiology Basics
📋 What it is
Microbes are living things too small to see — bacteria, fungi, and viruses — and most are harmless or helpful.
🗣️ Coach says
Microbes are life too tiny for the naked eye: bacteria, tiny fungi like yeast, and viruses. It’s easy to think "microbe = germ", but the vast majority are harmless or downright helpful. Only a small fraction cause disease. You need a microscope to meet them — and there are trillions around and inside you.

Why do antibodies fit their targets so well?
Because they lock onto a specific antigen like a key fits one lock!
😲 Whoa!
There are more microbes living on and in your body than there are human cells — you are, by cell count, more "microbe" than "you".
