Escherichia coli O55:H7 str. CB9615

Escherichia coli O55:H7 str. CB9615 is a Gram-negative, rod-shaped bacterium characterized by its facultative anaerobic metabolism, allowing it to thrive in various oxygen conditions. This strain exhibits mobility due to the presence of flagella and typically shows a cellular arrangement in pairs or singles. E. coli O55:H7 is mesophilic, with an optimal growth temperature of 37°C, which is consistent with its association with warm-blooded hosts. The bacterium has two replicons and is surrounded by two membranes, typical of Gram-negative organisms. It is nonsporulating and exists in a free-living biotic relationship, indicating that it can survive independently in its environment. E. coli strains, including O55:H7, are often associated with various ecological niches, particularly in the intestines of animals and humans. Their ability to adapt to different conditions and their mobility plays a critical role in their ecological dynamics, including nutrient cycling and interactions with other microbial communities. The specific traits of E. coli O55:H7 str. CB9615 highlight its adaptability and role within its habitat. Understanding these attributes can provide insights into its behavior in host environments and its potential impact on human and animal health. Further research may be necessary to explore its specific ecological roles and interactions within the microbiome.
