Escherichia coli O157 strain FDAARGOS_293

Escherichia coli O157 strain FDAARGOS_293 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 corresponds to the average body temperature of many warm-blooded hosts, indicating its strong association with host environments. As a facultative anaerobe, E. coli O157 can adapt to both aerobic and anaerobic conditions, enhancing its survival in diverse habitats within the host. The strain is predominantly found in host-associated habitats, suggesting a close relationship with its hosts, which may include humans and animals. This association likely plays a significant role in its ecological niche, influencing its growth dynamics and interactions within the microbiota of the host. Overall, the adaptability of E. coli O157 strain FDAARGOS_293 to varying oxygen levels and its optimal growth temperature reflect its evolutionary strategies for colonization and persistence in host-associated environments, underscoring the important role such traits play in the survival and ecological success of this microbe.
