Peptoniphilus harei strain NCTC13076

Peptoniphilus harei strain NCTC13076 is a Gram-positive, non-motile coccus that thrives as a chemoheterotroph within the gut of its host, Macaca fascicularis. This strain is classified as an anaerobe, indicating that it thrives in environments devoid of oxygen. Its optimal growth temperature is 37°C, placing it within the mesophilic temperature range, which is conducive to the typical body temperature of its primate host. Notably, Peptoniphilus harei strain NCTC13076 possesses a single replicon, reflecting a streamlined genetic structure common in many gut-associated bacteria. Its nonsporulating nature suggests that it relies on stable environmental conditions within the host gut for survival, rather than developing spores as a means of withstanding adverse conditions. The presence of flagella in Peptoniphilus harei strain NCTC13076 is an interesting trait, although its non-motility indicates that these structures may not function for locomotion but could have other roles, such as adherence to the gut lining or interaction with the host's immune system. The ecological role of Peptoniphilus harei strain NCTC13076 in the gut of Macaca fascicularis may involve the breakdown of complex organic compounds, contributing to the overall metabolic processes within the gut microbiome. This interaction suggests that Peptoniphilus harei could play a significant role in nutrient absorption and gut health, highlighting the importance of such microorganisms in the digestive ecology of primates.
