Microbiology
Microbiology is the scientific discipline focused on the study of microorganisms and of the effects they may have on other organisms. The term derives from the Greek words mīkros (meaning small), bios (meaning life), and logia (meaning study of). Generally, microorganisms are too small to be seen with the unaided eye. Microbiologists, scientists studying these small organisms, aid their observations with the use of such devices as microscopes (optical and electronic) and hand lenses.
Such organisms as bacteria, viruses, some algae and protozoa, and prions fall within the definition of microorganisms. Microorganisms constitute the majority of organisms; yet, only a very small percentage of the Earth's microbial species, populations and communities have been characterized scientifically.
