Prevotella copri

High levels of Prevotella copri and similar species are correlated with low levels of microbiota previously associated with immune regulating properties. In addition, some nutrients can alter intestinal permeability and thereby influence the immune response without a known impact on the microbiota. However, critical questions remain to be elucidated, such as the way microbiome fluctuates in relation to diet, and how disease activity may be influenced by changes in diet, microbiota or diet-intestinal microbiota equilibrium.

Dillon et al. [L] suggested that increased levels of P. copri might contribute to driving chronic inflammation in individuals infected with HIV. Furthermore, Lukens et al. [L] demonstrated gut dysbiosis with abundance of Prevotella in a mouse model of osteomyelitis.

Low levels of Prevotella copri can signify a potential imbalance in the gut microbiome. Prevotella copri is known for its role in carbohydrate and fiber fermentation and its presence is often linked to a diet rich in complex carbohydrates and fiber. Reduced levels might suggest a gut microbiota less optimized for the digestion of these types of foods, which could be due to a diet low in fiber or other factors affecting gut health. To address this, dietary changes are usually the first line of treatment. Increasing the intake of fiber-rich foods such as whole grains, legumes, fruits, and vegetables can promote the growth of Prevotella copri and other beneficial gut bacteria. Additionally, prebiotic foods, which provide nourishment for beneficial gut bacteria, may also help in increasing its levels. It's important to consult with a healthcare professional before making significant dietary changes or starting supplements, as they can provide tailored advice and monitor progress, ensuring that any intervention is appropriate and effective for individual health needs.

Prevotella copri is a gut bacteria that may cause rheumatoid arthritis. Studies consistently find different bacterial patterns in people with inflammatory arthritis vs controls.
