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.

Well explained with all its components. Better than reading 30 slides of ppt

Emocionado por el curso

Me gusta mucho más la introducción a este curso que la introducción aburrida que me dieron en la universidad. Se ve emocionante aprender el siguiente contenido

Top for medical students and interns
