Prevotella intermedia ATCC 25611 = DSM 20706 str. ATCC 25611 and strain-17

Prevotella intermedia ATCC 25611 (also known as DSM 20706 str. ATCC 25611 and strain-17) is a Gram-negative anaerobic bacterium belonging to the genus Prevotella. This species is characterized by its inability to utilize oxygen for growth, necessitating anaerobic conditions for optimal proliferation. As a member of the diverse microbial community, Prevotella intermedia is known to thrive in environments such as the human oral cavity and gastrointestinal tract, where it plays a role in the complex interplay of microbial interactions. The Gram-negative nature of Prevotella intermedia indicates that it possesses a thin peptidoglycan layer and an outer membrane containing lipopolysaccharides, which can influence its interactions with the host and other microorganisms. Its anaerobic requirement further highlights the importance of specific environmental conditions for its survival and growth, limiting its habitat to oxygen-depleted niches. Given the ecological role of Prevotella intermedia in the human microbiome, it is suggested that its presence may contribute to the metabolic processes associated with carbohydrate fermentation and the production of short-chain fatty acids, which are important for gut health. Moreover, its adaptation to anaerobic environments underscores the significance of microbial diversity in maintaining homeostasis within the host's microbiota. This adaptability to low-oxygen habitats allows Prevotella intermedia to participate actively in the degradation of dietary components, thereby influencing both nutrient availability and the overall metabolic landscape of its ecological niche.
