Escherichia coli strain K71-77

Escherichia coli strain K71-77 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 average body temperature of warm-blooded hosts, suggesting its adaptation to a host-associated habitat. As a facultative anaerobe, E. coli K71-77 can utilize oxygen for respiration when available but is also capable of surviving in anaerobic conditions, allowing it to inhabit various environments within a host. The ability of E. coli K71-77 to thrive in diverse oxygen levels may facilitate its survival in different niches within the host, potentially contributing to its ecological versatility. This adaptability to varying oxygen concentrations may also influence its interactions with other microbial species in the host microbiome. Understanding these traits enhances our knowledge of E. coli's ecological roles and its potential contributions to the overall microbial community dynamics within host organisms.
