Escherichia coli str. EC17GD31

Escherichia coli str. EC17GD31 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 conditions of its host-associated habitat. As a facultative anaerobe, E. coli str. EC17GD31 has the versatile ability to grow in both aerobic and anaerobic environments, allowing it to adapt to varying conditions within the host. The bacterium's Gram-negative nature suggests a complex cell wall structure, characterized by a thin peptidoglycan layer surrounded by an outer membrane containing lipopolysaccharides. This structural feature is indicative of the genus Escherichia, which is commonly found in the intestinal tracts of warm-blooded organisms. The host-associated nature of E. coli str. EC17GD31 points to a potential role in the gut microbiome, where it may contribute to the maintenance of intestinal health and functionality. The adaptability of E. coli str. EC17GD31 to different oxygen levels may enable it to occupy diverse niches within the host environment, facilitating its survival and potential interactions with other microbial inhabitants. Such versatility underscores the importance of this strain in understanding microbial dynamics and host-microbe interactions within the gastrointestinal tract.
