Microbes inhabit the world's oceans, deserts, lakes, soils, and atmosphere, and play a vital role in the Earth's biogeochemical cycles.  As humans, we harbor a diverse microbial flora estimated to outnumber our own human cells.  During this course, we will explore this microbial world by investigating the structure, physiology, genetics, and evolution of microorganisms with a focus on bacteria, but including discussions of archaea, viruses, and microbial eukaryotes. The goal of the course is to gain an understanding of the unique properties of microbes that enable their persistence and diversification.  We will also pay special attention to microbial interactions with eukaryotic organisms, by studying both host and microbe contributions to virulence, mutualism, and symbiotic relationships. Three hours of lecture and one hour of discussion per week.
