Summary

Bacteria are simple, unicellular organisms. Bacteria range in size from 0.1 to 15 µm, and the shape of most bacteria is either rod (bacillus), spherical (coccus), or spiral (spirillium). Bacteria are ubiquitous in nature. They are found in water, soil, organic matter, and living bodies of plants and animals. They have a wide variety of nutritional requirements and may be autotrophic, parasitic, or saprophytic with respect to the manner in which they obtain their nutritional requirements.
