by Vincent Racaniello, PhD, Sean Elliott, MD

Bacteria are single-celled prokaryotic organisms, believed to be the most ancient living organisms on Earth—so much so that mitochondria and chloroplasts likely evolved from bacteria that were engulfed by eukaryotes. Today, humans have a complex relationship with these organisms. While some are normal colonizers of body surfaces and tracts, and may even be integral to digestion, others have pathogenic potential and can thus be harmful.

In this course, the discussion will center around the most common bacterial pathogens in clinical practice. Additionally, the student will be introduced to the concept of the human microbiome, the basics of infection, bacterial toxins, and antimicrobial resistance.

For optimal comprehension, the student will be required to have preliminary knowledge of molecular and cellular biology, biochemistry, histology, and physiology. Familiarity with the biology of prokaryotic cells is strongly encouraged.

I dont understand the neg review. This is such a good lecture covering the key points. I found it very helpful

By Alrick C. on 02. May 2022 for Bacteria

The lecture is organized and precise. I would recommend it others. Moreover, it's less time consuming and as I said highlights what material is needed.

Italian New Yorker. Need I say more?
By Ghadeer K. on 10. March 2022 for Bacteria

The most fun I had learning about bacteria. That Italian New Yorker accent is everything! His E. coli lectures are the reason I passed my midterm and can totally discuss anything E. coli like a pro. So happy I discovered him and will definitely come back for more.

Great teacher

This is a very clarifying lecture on Listeria, taught by a professor with very good teaching skills. And kinda funny.
