Escherichia coli O128:H2 str. 2011C-3317

Escherichia coli O128:H2 str. 2011C-3317 is a Gram-negative, rod-shaped bacterium that is facultatively anaerobic, allowing it to thrive in both aerobic and anaerobic environments. This strain is known to inhabit host-associated environments, indicative of its potential role in the microbiota of various hosts. It exhibits a characteristic arrangement of cells in pairs and singles, which is typical of many E. coli strains. E. coli O128:H2 str. 2011C-3317 is motile, possessing flagella that enable it to move and navigate through its environment. The optimal growth temperature for this strain is 37°C, which aligns with the mesophilic temperature range, suggesting that it is well-adapted to the warm conditions found within host organisms. The strain contains a single replicon and exhibits a double membrane structure, consistent with the typical cell wall architecture of Gram-negative bacteria. Its free-living biotic relationship indicates that it can survive independently, although it is also associated with host environments. The ability of E. coli O128:H2 str. 2011C-3317 to thrive in host-associated habitats while also possessing free-living capabilities highlights its ecological versatility. This adaptability may allow it to play various roles in microbial communities, potentially influencing host health and contributing to the dynamics of gut microbiota.
