Escherichia coli str. JPH493

Escherichia coli strain JPH493 is a Gram-negative, rod-shaped bacterium typically found in pairs or as single cells. This strain thrives optimally at 37.0°C, a temperature that coincides with the physiological temperature of many mammalian hosts, indicating its adaptation to a host-associated habitat. As a facultative anaerobe, E. coli JPH493 can grow in both aerobic and anaerobic environments, allowing it to exploit various niches within its host's gastrointestinal tract. The ability to grow in diverse oxygen conditions suggests a metabolic flexibility that may enhance its survival and competitiveness in the complex microbial community typically residing in hosts. This characteristic is particularly relevant in the context of the gut microbiome, where fluctuating oxygen levels can occur. The rod shape and arrangement in pairs or singles may also contribute to its motility and colonization capabilities, facilitating interactions within its host environment. Overall, the traits of E. coli strain JPH493 underline its role as a versatile inhabitant of host-associated ecosystems, potentially contributing to the dynamic interactions that characterize microbial communities in health and disease. The strain exemplifies the adaptability of E. coli as a model organism in microbiological research, particularly in studies related to host-microbe interactions.
