Now that we know how to calculate serial dilutions, here are a few examples we will work through together. Please note: the very last dilution we discuss (1:625), 1/625 is patient serum, not saline. 624/625 is saline. Sorry for the error.

This video explains how to calculate serial dilutions.

This video explains the theory behind serial dilutions.

This video describes how the innate immune system reacts to a bacterial infection in a wound. Very simple and basic.

The zone of inhibition must be greater than or equal to 14mm to confirm Streptococcus pneumoniae. A D-test uses Clindamycin and Erythromycin to determine inducible Clindamycin resistance.

Information about catalase testing, and how to perform the test.

After your API20E has incubated overnight, it's time to add reagents, read your reactions, and calculate your results.

This video describes the setup of the Biomerieux API 20E test.

This video reviews different micro media (nutrient, differential, selective) and shows bacterial colony morphology on the agar. THIS IS NOT A PROFESSIONAL VIDEO. I put this together for my micro class. Note: on TCBS agar, Vibrio cholerae would grow yellow colonies. Other Vibrio species grow dark green colonies (as shown).

Made this during an Atlas Obscura class with Amanda Kelly of Panda Miniatures. I had a blast! Note: this is NOT a professional video! I just made it quickly to show the room and some close-ups.
