Escherichia coli M863

Escherichia coli M863 is a Gram-negative, rod-shaped bacterium that typically exists in pairs or as single cells. This strain is a facultative anaerobe, allowing it to thrive in both aerobic and anaerobic environments. E. coli M863 has an optimal growth temperature of 37.0°C, which aligns with the physiological temperature of many mammalian hosts, suggesting its adaptation to a host-associated habitat. The facultative anaerobic nature of E. coli M863 indicates that it can metabolize in the presence or absence of oxygen, providing it with a versatile ecological niche within host organisms. This metabolic flexibility may enable it to colonize various environments within the host, such as the intestines, where oxygen levels can vary. In summary, the adaptation of E. coli M863 to host-associated habitats and its metabolic versatility underscore its potential role in the complex microbial communities within mammalian hosts. Understanding these traits can provide insights into the ecological roles of E. coli strains in health and disease, particularly in relation to their interactions with the host's immune system and microbiota.
