Teaching

Biology 358

Microbiology lecture and laboratory emphasizes prokaryotic cell structure and function, gene regulation, horizontal gene transfer and host-microbe interactions.

Catalog Description: Full course for one semester. The biology of microorganisms, emphasizing prokaryotic anatomy, growth and cultivation, metabolism, genetics and gene regulation. Lecture topics include bacteria-to-bacteria signaling, biofilms, secretion, host-parasite interactions, microbial diversity, bacteriophage biology, and the use of phage as genetic tools. Lectures are supplemented with readings from the primary literature. Laboratory exercises demonstrate principles covered in lecture and instruct students on research techniques. An advanced, independent research project is required. Prerequisite: Biology 101/102, Chemistry 101/102. Lecture-laboratory.

Seminar on The Human Microbiome. Microbes comprise over 90% of the cells of the human body, and form distinctive communities in different regions of our bodies. The microbiome is a complex and dynamic community of microbes having major impact on human health. Using the primary literature, we will investigate how the microbiome intersects with organ development, the immune system, gut health and nutrient acquisition, autoimmunity, acute and chronic disease, dysbiosis and behavior.

Seminar on Bacterial Pathogenesis. An examination of how bacterial pathogens interact with host organisms in order to cause disease. Topics include adhesion, colonization, invasion, toxins, subversion of host cell signaling events, immune evasion, persisters, and bacteria-to-bacteria communication as they pertain to pathogenesis.

Immunology is a primarily lecture, conference course that will address basic principles of mammalian immunity. One inquiry-based laboratory exercise to investigate interleukin-2 production by lymphocytes will be conducted over two, regularly scheduled class periods.

Catalog Description: One-half course for one semester. A discussion of the properties of innate and adaptive immunity, the cells of the immune system, antibody structure and function, antigen recognition, lymphocyte activation and immunity to microbes. Topics also covered will include immunodeficiency and AIDS, and transplantation. An inquiry-based laboratory exercise will be required.  Prerequisites: Biology 101/102 and one of Biology 358 or 372.
