ABSTRACT
MICR 290: Microbiology explores the structure, function,
and classification of microorganisms, including bacteria,
viruses, fungi, and parasites. The course covers microbial
genetics, metabolism, growth, and methods of control, as
well as the role of microbes in health, disease, and
biotechnology. Students study immune system responses,
disease transmission, and antibiotic resistance. Laboratory
work emphasizes aseptic techniques, microbial culturing,
staining, and identification methods. Emphasis is placed on
understanding real-world applications, including infectious
disease management and microbial biotechnology. By
integrating theory with hands-on experience, MICR 290
provides a strong foundation in microbiology for students
pursuing health science and related fields.
