by Vincent Racaniello, PhD, Sean Elliott, MD

Infectious diseases have burdened humanity for millennia. Concepts of contagion and its prevention have slowly developed in different cultures over centuries. In the 19th century, Louis Pasteur introduced the germ theory of disease, which described the relationship between microorganisms and illnesses. Microbiology is the branch of biology that focuses on the study of these microorganisms and their relationship to disease processes by describing their characteristics (e.g. species, structure, virulence factors, etc.). Since not all microorganisms are pathogens, and some are actually beneficial to humans, microbiology provides a way to understand the difference between the two.

In this course, the student will be taught about the major groups and families of microorganisms relevant to human health, including bacteria, viruses, fungi, parasites, and prions. For optimal comprehension, the student is required to have a basic understanding of eukaryotic and prokaryotic cells and the differences between them, and basic concepts of gene expression.

In the previous century, infectious diseases were the most important causes of morbidity and mortality. After the advent of antibiotics, these diseases have become relatively less prevalent and not as morbid as they used to be. However, they are still encountered in clinical practice, and a competent physician must have a good grasp on the most common pathogens in their area of work to have a clearer understanding of the pathophysiology of which they are a part of, of effective pharmacological therapies, and of mechanisms of resistances.
