A microbe, short for microorganism, is a microscopic organism that can only be seen with the aid of a microscope. Microbes include bacteria, archaea, fungi, protists, and viruses. Some are beneficial, playing vital roles in nutrient cycling and decomposition, while others are pathogenic and cause disease. They are found everywhere on Earth, from soil and water to the human body. Think of them as the invisible workforce of our planet, both helpful and harmful.
The word 'microbe' is a shortened form of 'microorganism.' 'Micro' comes from the Greek word *mikros*, meaning 'small.' 'Organism' refers to a living thing. Therefore, a microbe is a small living thing. The term came into common use in the late 19th century with the rise of microbiology.
