Escherichia coli O139:H28 str. E24377A

Escherichia coli O139:H28 str. E24377A is a Gram-negative, rod-shaped bacterium that typically exists in pairs or as single cells. This strain demonstrates a facultative anaerobic metabolism, allowing it to thrive in both aerobic and anaerobic environments. Its optimal growth temperature is 37.0°C, which is consistent with the body temperature of warm-blooded hosts, indicating its adaptation to a host-associated habitat. As a member of the Enterobacteriaceae family, E. coli O139:H28 str. E24377A is often found within the intestinal tracts of mammals, where it plays a role in the complex microbial community. The facultative anaerobic nature of this strain suggests that it can efficiently utilize various metabolic pathways depending on the availability of oxygen, which may contribute to its survival in diverse environments within the host. The ecological insights provided by the traits of E. coli O139:H28 str. E24377A highlight its potential adaptability in fluctuating conditions within the host's gut. This adaptability may facilitate its persistence in the microbiome and underscore its significance in studies focusing on microbial interactions and host health. Further research could illuminate the specific roles this strain plays in gut ecology, nutrient cycling, and its interactions with other microbial species.
