Escherichia coli strain FWSEC0290

Escherichia coli strain FWSEC0290 is a Gram-negative, rod-shaped bacterium that typically exists in pairs or as single cells. This strain thrives optimally at a temperature of 37.0°C, which is consistent with the body temperature of its host organisms, indicating its adaptation to a host-associated habitat. E. coli FWSEC0290 is classified as a facultative anaerobe, allowing it to metabolize in both aerobic and anaerobic environments, which enhances its survival and versatility within various host niches. The ability of E. coli FWSEC0290 to exist as single cells or in pairs may facilitate its interactions with the host’s immune system and microbiota, potentially influencing its ecological role within the host. Given its habitat and physiological characteristics, this strain may play a significant role in the microbial community dynamics within the gastrointestinal tract of mammals, contributing to nutrient metabolism and gut health. The adaptability of E. coli FWSEC0290 to fluctuating oxygen levels further underscores its importance in host-associated ecosystems, where oxygen availability can vary significantly. Understanding the specific interactions and functions of this strain within its environment could provide valuable insights into the broader ecological roles of E. coli in host-associated habitats.
