Description

Bifidobacterium dentium B764 is a Gram-positive, rod-shaped bacterium that thrives in anaerobic conditions, commonly found in the oral cavity, active carious lesions, and fecal samples of humans. This species is characterized by its mesophilic nature, indicating it prefers moderate temperature ranges for growth. Notably, B. dentium B764 does not exhibit mobility, as it lacks flagella. This bacterium has a significant relationship with human health, particularly in the context of dental caries. The presence of B. dentium in oral biofilms suggests it plays a role in the complex microbial ecosystem of the mouth, where it may contribute to the dynamics of carious lesions. The bacterium's ability to inhabit various niches within the oral environment and saliva underscores its adaptability and potential impact on oral health. Given that B. dentium B764 is free-living and has two replicons, it demonstrates genetic complexity that may influence its survival and function in diverse environments. The study of this bacterium may provide insights into the microbial interactions within the oral cavity and their implications for dental health. Understanding its role in dental caries could guide future strategies in oral microbiome management and disease prevention. The accessions for B. dentium B764, LR134349.1 and AP012326.1, serve as important resources for further research into its genetic and functional characteristics.
