Escherichia coli strain ECSW+04

Escherichia coli strain ECSW+04 is a Gram-negative, rod-shaped bacterium that typically exists in pairs or as single cells. This strain is facultatively anaerobic, indicating its ability to thrive in both aerobic and anaerobic environments, which is a characteristic feature of many E. coli strains. The optimal growth temperature for ECSW+04 is approximately 37.0 degrees Celsius, aligning with the typical physiological conditions of the mammalian host environment in which it is often found. E. coli strains, including ECSW+04, are commonly associated with the intestines of warm-blooded animals, suggesting a host-associated habitat. This association underscores the bacterium's adaptability and potential role in various biological processes within the host, such as nutrient absorption and gut microbiota composition. The ability to exist in pairs and as single cells may provide advantages in colonization and survival within the dynamic environment of the gastrointestinal tract. Understanding the traits of E. coli strain ECSW+04 enhances our knowledge of its ecological niche and potential interactions with the host microbiome. The facultative anaerobic nature of this strain may contribute to its survival strategies in varying oxygen conditions within the host, illustrating the bacterium's flexibility and resilience in diverse environmental contexts. This adaptability could also provide insights into the role of E. coli in maintaining gut health and influencing host metabolism.
