Escherichia coli O145:H28 str. RM12581

Escherichia coli O145:H28 str. RM12581 is a Gram-negative bacterium characterized by its rod shape and mobility, facilitated by the presence of flagella. This strain is a facultative anaerobe, allowing it to thrive in both aerobic and anaerobic environments. E. coli O145:H28 is predominantly found in host-associated habitats, indicating its association with living organisms. The optimal growth temperature for this strain is 37°C, placing it within the mesophilic temperature range suitable for human and animal hosts. E. coli O145:H28 possesses a complex genetic structure, with three replicons contributing to its genetic diversity and adaptability. The bacterium is surrounded by two membranes, typical of Gram-negative bacteria, which play a crucial role in its interaction with the environment and host. E. coli strains, including O145:H28, are known for their biotic relationships, as they can exist as free-living organisms or as part of the microbial flora in the intestines of various hosts. This versatility suggests that E. coli O145:H28 may contribute to various ecological functions, such as nutrient cycling and maintaining gut health in host organisms. Understanding the traits of E. coli O145:H28 can provide insights into its role in both health and disease, given that some E. coli strains are associated with pathogenicity. The specific genetic and physiological characteristics of this strain may influence its ecological niche and interactions within microbiomes.
