Agathobacter rectalis strain AF12-8

Agathobacter rectalis strain AF12-8 is a Gram-positive, non-motile, rod-shaped bacterium classified as a chemoheterotroph. This strain is anaerobic, thriving in environments devoid of oxygen. It is typically found in multiple habitats, including those associated with Homo sapiens, indicating its potential role in human-associated microbiomes. The optimal growth temperature for A. rectalis strain AF12-8 is 37°C, placing it within the mesophilic temperature range. The bacterium possesses one membrane and one replicon, characteristics that are common among certain anaerobic bacteria. Notably, A. rectalis strain AF12-8 does not undergo sporulation, suggesting that it relies on other survival strategies in its anaerobic habitats. The presence of flagella in A. rectalis strain AF12-8 may suggest some form of mobility; however, the organism is classified as non-motile. This discrepancy highlights the complexity of microbial classification and the need for further research to clarify the implications of flagella presence in this context. Ecologically, A. rectalis strain AF12-8's free-living nature and association with human hosts suggest it may play a role in the human gut microbiome, where it could contribute to various metabolic processes. Understanding its traits and ecological role can provide insights into its potential benefits or impacts on human health, particularly in the context of gut microbiota dynamics. The accession number for this strain is QSAE00000000.1, which aids in its identification and study within microbiological databases.
