Escherichia coli strain FWSEC0443

Escherichia coli strain FWSEC0443 is a Gram-negative, rod-shaped bacterium that typically arranges itself in pairs or as single cells. This strain thrives optimally at 37.0°C, a temperature that aligns with the physiological conditions of its host-associated habitat. As a facultative anaerobe, FWSEC0443 can adapt to varying oxygen levels, allowing it to survive in diverse environments within the host. The ability to grow in both aerobic and anaerobic conditions highlights the metabolic versatility of this strain, which may play a crucial role in its interaction with the host's microbiome. Such adaptability could facilitate its survival in the fluctuating oxygen environments commonly encountered in host-associated niches. Therefore, understanding the ecological role of E. coli FWSEC0443 may provide insights into its contributions to host health and the dynamics of microbial communities within the gastrointestinal tract.
