Bacteroides is a genus of gram-negative anaerobic bacteria that inhabit the human gut. These bacteria are known for their ability to ferment a variety of carbohydrates, leading to the production of short-chain fatty acids that provide energy to the body. While bacteroides is the official name for this group of bacteria, there are also several synonyms that can be used interchangeably. Some of these synonyms include Bacteroide, Porphyromonas, and Prevotella. These bacteria play a crucial role in maintaining the balance of the gut microbiome and have been linked to various health benefits, including improved digestion, immune function, and mental health.
