What are bacteria?

Bacteria (singular: bacterium) are one-celled organisms visible only through a microscope. There are many types of bacteria, only some of which cause disease. Most are harmless and even some are helpful (good bacteria), by aiding digestion or breaking down rotting material. Bacteria are found almost everywhere.
