Escherichia coli O121:H19

Escherichia coli O121:H19 is a Gram-negative, rod-shaped bacterium that is facultatively anaerobic and capable of mobility due to the presence of flagella. This strain typically exists in pairs or singles and is known to thrive in host-associated habitats. It has an optimal growth temperature of 37°C and falls within the mesophilic temperature range. E. coli O121:H19 possesses a single replicon and is characterized by having two membranes, which is typical of Gram-negative bacteria. Its ability to live freely and its adaptability to different environments highlight its ecological versatility. As a member of the E. coli species, it can be found in various hosts, including humans, and may play a role in the gut microbiome. The traits of E. coli O121:H19 illustrate its potential for survival and adaptation in diverse environments, particularly in host-associated habitats. Understanding these characteristics can provide insights into its ecological roles and implications for health, especially given the pathogenic potential associated with certain E. coli strains. The accession number for this strain is NZ_CP031911.1, which can be used for further research into its genomic and phenotypic properties.
