Escherichia coli O118:H16 str. 2009C-4446

Escherichia coli O118:H16 str. 2009C-4446 is a Gram-negative rod-shaped bacterium that typically exists in pairs or singles. This strain thrives optimally at 37.0°C, which is consistent with the body temperature of its host organisms, indicating a potential adaptation to a host-associated habitat. E. coli O118:H16 str. 2009C-4446 exhibits facultative anaerobic metabolism, allowing it to survive in both aerobic and anaerobic environments. As a member of the Enterobacteriaceae family, this strain is likely to be part of the normal intestinal flora of various hosts, where it may play a role in nutrient processing and maintaining gut health. The ability to adapt to varying oxygen levels may confer a survival advantage in the complex and fluctuating environments found within the intestines of mammals. Overall, the ecological significance of E. coli O118:H16 str. 2009C-4446 could be linked to its metabolic flexibility and association with host organisms, highlighting the importance of such bacterial strains in the broader context of gastrointestinal microbiota and their contributions to host well-being.
