Microbiology

Microbiology is the scientific study of living things too small to see with the naked eye, such as bacteria, viruses, fungi, and single-celled organisms called protozoa. These microorganisms are found everywhere—in soil, water, food, and inside our bodies—and they play crucial roles in everything from digesting food to causing disease to recycling nutrients in nature. By studying them, scientists can develop medicines, prevent infections, and understand the hidden microscopic world that shapes our everyday lives.
