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.

Exellent lecture. Thank for teaching me. Enjoy teaching you are best.

The lecturer teaches the subjects in a way simple to learn.
By Romina y. on 11. September 2022 for Bacteria

It is clear and well organized so that I could learn the subjects which seemed complicated when the lecturer presented them in university. It also made me interested in microbiology which I didn't even like to learn it. Thank you
