Microbiology is the study of tiny living things, such as bacteria, viruses, fungi, and some algae, that are too small to see without a microscope. It explores how these microorganisms live, grow, and affect other living things.
From Greek ‘mikros’ meaning ‘small,’ ‘bios’ meaning ‘life,’ and ‘-logia’ meaning ‘study of.’ The term emerged in the 19th century as scientists began to understand microscopic life.
