These microscopic living organisms include bacteria; fungi, such as mold spores; dust mites; viruses; protozoa and algae. While most microorganisms are beneficial, bacteria are capable of causing allergic reactions, respiratory disorders, hypersensitivity and, of course, infectious diseases. Viruses are the cause of certain illnesses and disease (cold and flu are common examples). The by-products of fungi and dust mites are also capable of causing allergic reactions and other problems.

Bacteria and other microbes are also the source of many foul odors. In the process of feeding on organic matter such as urine, body fluids and other waste, microbes may release unpleasant-smelling gases into the air.

Beneficial bacteria are being harnessed to clean without the use of harmful chemicals. Since microbes eat organic matter by releasing enzymes, 'friendly' microbes are powerful allies in cleaning restrooms, removing pet urine from deep inside carpet, keeping drains running free, and even removing spots from your laundry.

While live microbes (spore forms) are used in carpet spotters and drain cleaners, laundry detergents only use the non-living enzymes harvested from the microbes.

Technical definitions of the different kinds of microbes appear elsewhere in HC-Pedia. See the entries Bacteria; Disinfectant; and Virus.
