Faecalibacterium prausnitzii strain AF31-14AC

Faecalibacterium prausnitzii strain AF31-14AC is a Gram-positive, non-sporulating anaerobic bacterium that exhibits a rod shape and does not possess mobility, lacking flagella. This strain is classified as a chemoheterotroph, indicating that it derives its energy from organic compounds. The optimal growth temperature for AF31-14AC is 37°C, placing it within the mesophilic temperature range suitable for growth in warm-blooded hosts. This strain has been identified in multiple habitats, notably associated with various hosts, including Homo sapiens (humans), Gallus gallus (chickens), as well as other metazoans and primates such as Macaca mulatta and Macaca fascicularis. The presence of Faecalibacterium prausnitzii in the gut microbiota of these diverse organisms suggests its potential role in the gut ecosystem across different species. Additionally, strain AF31-14AC has a single replicon, simplifying its genomic organization. The analysis and characterization of this strain contribute to understanding its ecological significance, particularly in the context of human health, as Faecalibacterium prausnitzii is often recognized for its beneficial effects on gut health and its association with anti-inflammatory properties. Overall, the presence of this strain in various hosts highlights its potential importance in both microbial ecology and host-microbe interactions.
