Prokaryotes: examples

There are many types of bacteria. Some are directly beneficial to us, as they help our digestive systems to function effectively. Some play fundamental roles in global ecosystems, such as decomposition and nutrient recycling.

But some can be very harmful and cause disease. These are termed pathogenic bacteria, such as: Bacillus anthracis, which causes Anthrax; Vibrio cholorae, which causes Cholera; and Mycobacterium tuberculosis, which causes Tuberculosis.
