There are both beneficial and pathogenic bacteria- Beneficial bacteria are involved in such diverse processes as digestion in animals, nitrogen fixation in the roots of certain legumes, the decomposition of animal and plant remains, and sewage disposal systems' Pathogenic bacteria, on the other hand, cause Severe and often, fatal diseases in humans, animals, and plants.
