Bacteria; Bacteroidetes/chlorobi group Phylum; Bacteroidetes Class; Bacteroidia Order; Bacteroidales Family; Prevotellaceae Genus: Prevotella (1)


Genus species: Prevotella copri (1)

Description and significance

Prevotella copri is a gram-negative bacteria. The cells are anaerobic and do not form spores. The cells grow best at 37 degree Celsius and are rod shaped.(2) Prevotella copri is an intestinal bacteria, and its anaerobic qualities allows it to grow successfully in the human gut and intestines.(3)


Environment: Our intestines are home to many different types of microbes. Prevotella copri is one of these many intestinal bacteria. Bacteria in the gut have many different purposes. The bacteria help in the digestion of food as well as help to keep harmful bacteria at bay.(3)

Current Research

Recent studies have shown a correlation between Prevotella copri and the development of rheumatoid arthritis. Although the evidence has not been conclusive it is believed that Prevotella copri causes a reduction of other beneficial microbes. One study done on mice showed that mice with Prevotella copri had more severe disease than the control mice. Prevotella copri has shown to be more prevalent in patients with rheumatoid arthritis than with healthy individuals. Although a definitive link cannot be made to increased Prevotella copri and rheumatoid arthritis, studies are still being conducted to determine what effect Prevotella copri has on this autoimmune disease.(3)

Include information about how this microbe (or related microbes) are being studied and for what purpose
