Escherichia coli strain VL119

Escherichia coli strain VL119 is a Gram-negative, rod-shaped bacterium that typically exists in pairs or as single cells. This strain, like other members of the species, thrives optimally at a temperature of 37.0°C, which corresponds with the average body temperature of warm-blooded hosts, indicating its adaptation to a host-associated habitat. E. coli strain VL119 is classified as a facultative anaerobe, allowing it to grow in both aerobic and anaerobic environments, which enhances its survival and versatility within various host conditions. The facultative anaerobic nature of E. coli strain VL119 suggests that it can utilize different metabolic pathways depending on the availability of oxygen, thereby contributing to its resilience and ecological success in diverse environments. This adaptability not only allows the bacterium to occupy ecological niches within the gastrointestinal tract of hosts but may also play a role in its interactions with the host microbiome, potentially influencing nutrient availability and metabolic processes. Overall, the traits of E. coli strain VL119 highlight its evolutionary advantage as a versatile inhabitant of host-associated environments.
