Escherichia coli str. RS571

Escherichia coli strain RS571 is a Gram-negative, rod-shaped bacterium that typically exists in pairs or as single cells. This strain is a facultative anaerobe, indicating its ability to thrive in both aerobic and anaerobic environments. E. coli RS571 has an optimal growth temperature of 37.0°C, which aligns with the typical mammalian host body temperature, suggesting its adaptation to a host-associated habitat. The species E. coli is widely recognized for its role in the intestinal microbiota of various hosts, where it contributes to nutrient absorption and the maintenance of gut health. While specific details regarding strain RS571's interactions within its host are not provided, its facultative anaerobic metabolism implies a versatile capability to utilize various substrates for energy, which can be advantageous in fluctuating oxygen levels within the host environment. The ability of E. coli RS571 to grow under varying oxygen conditions may allow it to colonize diverse niches within the host, potentially influencing gut microbiome dynamics and host health. This adaptability underscores the ecological significance of E. coli strains, including RS571, in maintaining the stability of microbial communities in host-associated environments.
