In this video, we'll be bold and dive right into perhaps one of the most important bacteria you'll learn about in microbiology: *Staphylococcus aureus*. The name *Staphylococcus aureus* tells us a decent amount right from the start. "Staph" and "coccus" come from Greek, meaning "grape" and "granule," respectively, because under the microscope, *Staphylococci* look like a bundle of grapes.

We'll tend to use a l...
