MicroorganismsMicroorganisms (micro= little) are diverse and specialized living things. They exist everywhere, are typically invisible to the naked eye and can only be seen by a microscope. They include bacteria, viruses, fungi, parasites and protozoa. Note: Not all micro-organisms are pathogens (these cause disease). For example, most bacteria are helpful to the human body.
