Escherichia coli str. U14A

Escherichia coli str. U14A 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, reflecting its adaptation to a host-associated habitat. As a facultative anaerobe, E. coli str. U14A can grow in both aerobic and anaerobic conditions, allowing it to exploit a range of environments within the host. The ability to thrive in diverse oxygen conditions may confer an ecological advantage, enabling this strain to occupy niches in various host tissues where oxygen availability can fluctuate. This adaptability is a key feature of many E. coli strains, facilitating their persistence and survival in the complex microenvironments of their hosts. Understanding the physiological traits of E. coli str. U14A enhances our knowledge of its ecological role and potential interactions within host-associated microbial communities.
