Escherichia coli strain NCTC9702

Escherichia coli strain NCTC9702 is a Gram-negative, rod-shaped bacterium that typically occurs in pairs or as single cells. This strain thrives at an optimal temperature of 37.0°C, which aligns with the body temperature of many warm-blooded hosts, indicating its adaptation to a host-associated habitat. E. coli NCTC9702 is classified as a facultative anaerobe, allowing it to grow in both aerobic and anaerobic environments, thereby enhancing its survival in diverse conditions within its host. The ability of E. coli NCTC9702 to inhabit the intestinal tract of its host contributes to its role in the gut microbiota, where it may participate in various metabolic processes, including the fermentation of carbohydrates and the synthesis of essential vitamins. Its facultative anaerobic nature provides a competitive advantage in fluctuating oxygen conditions found in the gut, allowing it to adapt to the dynamic environment of the gastrointestinal tract. Moreover, the presence of E. coli strains such as NCTC9702 within the microbiome may influence host health by modulating immune responses and competing with pathogenic microorganisms. Understanding the specific traits of this strain can provide insights into its ecological role and potential interactions within the microbiota, emphasizing the importance of E. coli in maintaining gut homeostasis and overall host health.
