Prevotella Strains

Prevotellastrains are Gram-negative, non-motile, rod-shaped, singular cells that thrive in anaerobic growth conditions. Prevotella spp. is one of the most abundant microorganisms cultured from the rumen and hindgut of cattle and sheep, where they contribute to the breakdown of protein and carbohydrate foods. They are also present in humans, where they may be opportunistic pathogens.

Prevotella is often thought of as a bacterium associated with a healthy plant-based diet that acts as a "probiotic" in the body. Decreases in Prevotella spp. are associated with certain diseases such as autism, allergies, multiple sclerosis, etc. In addition, Prevotella-driven enterotypes were positively correlated with animal traits, including feed intake, feed efficiency, body weight gain and incidence of diarrhea, suggesting that Prevotella is important in mediating growth performance and disease resilience in farmed animals. Prevotella is a highly connected taxon that exhibits strong competitive and cooperative interactions with many members of the gut microbiota and has a profound impact on the community structure and function of the animal gut microbiota.
