Focuses on the study of structure, growth, pathogenicity and genetics of microbes as well as their interactions in microbiome and biofilm communities. In the laboratory, students will learn sterile technique, staining, and culture techniques required for the isolation, identification, and enumeration of microbes, microbial metabolism, microbial genetics and will investigate various factors affecting microbial growth, including antiseptics, disinfectant, and antimicrobial drugs. An independently designed and executed, small-group research project is completed in the laboratory and culminates in a student research symposium. Three hours lecture and four hours laboratory. Prerequisite: BIO-239 and CHM-111, each with a minimum grade of C or permission of the instructor. [ 4 credits ]
