Examples of Bacteria
Bacteria are the plural of bacterium, which are microscopic one-celled organisms. They are found everywhere and can be harmful, as in infections; or they can be beneficial, as in fermentation or decomposition. Five types of bacteria are: Coccus, Bacillus, Spirillum, Rickettsia, and Mycoplasma.
