Phocaeicola plebeius strain AM17-44

Phocaeicola plebeius strain AM17-44 is a Gram-negative, non-motile rod that resides in the intestinal microflora of various animal hosts, including Homo sapiens (humans), Gallus gallus (chickens), and Bos (cattle). As a chemoheterotroph, this strain relies on organic compounds for energy, thriving in anaerobic conditions. The strain is mesophilic, with an optimal growth temperature of 37°C, which aligns with the typical body temperature of its mammalian hosts. The presence of a single replicon indicates a streamlined genomic organization, potentially contributing to its adaptability within the gut environment. Notably, Phocaeicola plebeius strain AM17-44 is nonsporulating, meaning it does not form spores as a survival mechanism under adverse conditions. This trait may limit its resilience compared to sporulating bacteria, but it could also reflect its adaptation to a stable, nutrient-rich intestinal habitat. This bacterium’s role in the gut ecosystem is significant, as it participates in the complex interplay of microbial communities that contribute to host health. Its presence in the intestinal microflora suggests potential implications for digestion, nutrient absorption, and overall gut microbiome dynamics. Further studies could elucidate its specific functions and interactions within the gut, enhancing our understanding of microbial ecology in both humans and animals.
