Microbiology is the study of microscopic organisms such as bacteria, viruses, fungi, protozoa, and algae. It explores their physiology, genetics, pathogenicity, ecology, and role in human health and the environment. Students learn about immunology, medical microbiology, industrial and environmental microbiology, and microbial biotechnology. A degree in Microbiology opens career paths in healthcare, pharmaceuticals, research labs, food and beverage industries, environmental agencies, and public health institutions.
