Prevotella strains are Gram-negative, non-motile, singular cells that thrive in anaerobic growth conditions. They are generally host associated and most species exist as obligate anaerobes (Finegold, 1996). Prevotella species are present in humans, often existing in the oral cavity, gastrointestinal tract, and vagina (Avguštin et al., 2001). In humans, they can act as an opportunistic pathogen, causing periodontal and tooth problems such as gingivitis and periodontitis (Finegold, 1996).
