COURSE GOALS:
• The student will gain a basic understanding of the structure and function of microorganisms as well
as their role in health and disease.
• The student will learn the basic laboratory skills prerequisite to working with microbes in further
coursework or in a medical or industrial setting.
• The student will gain a basic understanding of the immune system and its applications, as well as its
