Escherichia coli strain CRE10

Escherichia coli strain CRE10 is a Gram-negative, rod-shaped bacterium that typically presents in pairs or as single cells. This strain exhibits a facultative anaerobic metabolism, allowing it to thrive in environments with or without oxygen. Optimal growth occurs at 37.0°C, which is consistent with the typical human body temperature, indicating a close association with host organisms. As a member of the Enterobacteriaceae family, E. coli strain CRE10 is primarily found in host-associated habitats, suggesting an adaptation to living in the gastrointestinal tract of warm-blooded animals. The ability to exist in both aerobic and anaerobic conditions may provide this strain with a competitive advantage in fluctuating microenvironments within the host, where oxygen levels can vary significantly. The unique combination of traits observed in E. coli strain CRE10 positions it as an important organism for further investigation, particularly in understanding the dynamics of microbial communities in the gut and their interactions with the host immune system. Given its association with host environments, studying this strain may reveal insights into the roles of specific E. coli strains in health and disease, as well as their potential impacts on nutrient absorption and gut microbiota composition.
