Escherichia coli O26:H11 str. 21765

Escherichia coli O26:H11 str. 21765 is a Gram-negative, rod-shaped bacterium characterized by its occurrence primarily in pairs or as single cells. This strain exhibits a facultative anaerobic metabolism, allowing it to thrive in both aerobic and anaerobic environments, and is optimally adapted to temperatures around 37.0°C, which is consistent with the physiological conditions of its host-associated habitat. E. coli O26:H11 str. 21765 is part of a diverse group of E. coli strains, some of which are known to inhabit the intestines of warm-blooded animals, including humans. The specific ecological niche occupied by this strain may influence its interactions with the host microbiome and its potential roles in nutrient cycling and host health. Given its association with host environments, further investigation into the ecological and biological activities of E. coli O26:H11 str. 21765 could provide insights into its contributions to gut microbiota stability and its responses to varying oxygen levels within the gastrointestinal tract. Understanding the specific adaptations of this strain may also shed light on its potential interactions with other microbial species present in the host environment.
