Escherichia coli O145:H28 str. RM12581

Escherichia coli O145:H28 str. RM12581 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 coincides with the physiological temperature of many mammalian hosts, indicating its adaptation to a host-associated habitat. As a facultative anaerobe, E. coli O145:H28 str. RM12581 possesses the metabolic flexibility to utilize both aerobic and anaerobic respiration, allowing it to survive in various microenvironments within its host. The ability to grow in diverse oxygen conditions suggests a versatile ecological role within the host's microbiome, potentially contributing to nutrient cycling and maintaining gut homeostasis. The physiological traits of this strain may offer insights into its interactions within host-associated environments, emphasizing the importance of understanding microbial communities in health and disease contexts. As research continues to uncover the functions and dynamics of such bacteria, E. coli O145:H28 str. RM12581 may represent a valuable model for studying host-microbe interactions in broader ecological settings.
