Escherichia coli O145 str. RM9872

Escherichia coli O145 str. RM9872 is a Gram-negative, rod-shaped bacterium that typically exists in pairs or singles. This strain is characterized as a facultative anaerobe, indicating it can grow in both the presence and absence of oxygen. E. coli O145 str. RM9872 is motile, possessing flagella that facilitate its movement. The optimal growth temperature for this strain is 37°C, and it falls within the mesophilic temperature range. This bacterium has a unique genomic structure, comprising two replicons and two membranes, which is typical for members of the Enterobacteriaceae family. E. coli O145 str. RM9872 is associated with host organisms yet is also classified as free-living, indicating its ability to survive independently in various environments. The two accession numbers, NZ_CP028380.1 and NZ_CP028379.1, provide references to its genomic data, which could be valuable for further studies on its genetic characteristics and potential applications in microbiology. In ecological terms, the ability of E. coli O145 str. RM9872 to thrive as a free-living organism while also being host-associated suggests its versatility in adapting to different environments. This adaptability may play a significant role in its ecological interactions, including its potential impact on gut microbiota and its involvement in nutrient cycling within host-associated habitats.
