Faecalibacterium prausnitzii strain AHMP21

Faecalibacterium prausnitzii strain AHMP21 is a Gram-positive, non-motile, anaerobic bacterium characterized as a chemoheterotroph. It exhibits a rod shape and thrives optimally at a temperature of 37°C, indicating its mesophilic nature. This strain is part of a diverse habitat, being associated with multiple hosts, including Homo sapiens (humans), Gallus gallus (chickens), various Metazoa, Aves (birds), and primates such as Macaca mulatta and Macaca fascicularis. F. prausnitzii is known for its role in the gut microbiome, where it contributes to gut health and immune function. Importantly, this strain does not form spores, which can be a crucial trait for its survival and functionality in the gastrointestinal tract of its hosts. The presence of a single replicon suggests a simplified genetic structure, which may reflect its specialized adaptations to the anaerobic environments typically found in intestinal ecosystems. Overall, the ecological role of Faecalibacterium prausnitzii is significant, as it has been associated with anti-inflammatory properties and the maintenance of gut homeostasis. Its association with multiple hosts underscores its adaptability and potential importance in the microbiomes of various vertebrates, including humans. Thus, the presence of this strain may reflect health status and contribute to the understanding of gut microbiota dynamics across different species.
