Criibacterium bergeronii

Criibacterium bergeronii is a species of bacteria that predominantly inhabits the gut of humans (Homo sapiens). It exhibits a rod shape and is classified as Gram-negative. This bacterium is non-motile, lacking flagella despite their presence in the classification. It thrives under anaerobic conditions, meaning it does not require oxygen for its metabolic processes. As a chemoheterotroph, Criibacterium bergeronii derives its energy from organic compounds, utilizing a variety of substrates found within the host gut. Optimal growth occurs at a temperature of 35°C, situating it within the mesophilic temperature range, which is conducive to the growth of many gut-associated microorganisms. The bacterium has a single replicon, indicating a relatively simple genomic structure. Notably, Criibacterium bergeronii does not form spores, which suggests a reliance on stable environmental conditions within its gut habitat for survival. The presence of this bacterium in the human gut may play a role in the complex ecosystem of gut microbiota, contributing to the overall health and metabolic activities within the digestive system. The interactions between Criibacterium bergeronii and other microbial species, as well as their collective influence on host health, underscore the importance of understanding gut microbiomes and their inhabitants. This understanding can provide insights into potential therapeutic targets for gut-related health issues.
