Escherichia coli strain FWSEC0401

Escherichia coli strain FWSEC0401 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 aligns with the physiological temperature of many mammalian hosts, suggesting its adaptation to a host-associated habitat. As a facultative anaerobe, FWSEC0401 can grow in both the presence and absence of oxygen, allowing it to exploit diverse metabolic environments within host organisms. The host-associated nature of this strain indicates a potential role in the microbial communities found within the gastrointestinal tracts of animals, where E. coli species are commonly present. Its ability to thrive at body temperature and adapt to varying oxygen levels may provide insights into its interactions with the host's immune system and its potential contributions to gut microbiota dynamics. Understanding these traits could lead to further exploration of the ecological roles of E. coli strains like FWSEC0401 in health and disease contexts, emphasizing their importance in microbial ecology and host-microbe interactions.
