This process is called chemosynthesis and involves the use of chemical substances for the production of energy.
Many heterotrophic bacteria also cause diseases such as strep throat, rheumatic fever, cholera, gonorrhea, syphilis, and toxic shock syndrome. Bacteria can cause disease by destroying cells, releasing toxins, contaminating food, or by the reaction of the body to the infecting bacteria.almonella is a genus of rod-shaped bacterium whose species cause typoind fever and similar illnesses.
