Escherichia coli O69:H11 str. 08-4661

Escherichia coli O69:H11 str. 08-4661 is a Gram-negative, rod-shaped bacterium that typically exists in pairs or as single cells. This strain thrives optimally at 37.0°C, which aligns with its adaptation to host-associated habitats. As a facultative anaerobe, E. coli O69:H11 str. 08-4661 can metabolize in both the presence and absence of oxygen, allowing it to occupy various niches within host organisms. The Gram-negative nature of this bacterium is indicative of its cell wall structure, which includes a thin peptidoglycan layer and an outer membrane containing lipopolysaccharides. These features are significant for understanding its interactions with the host environment and potential implications for immune responses. The rod shape and ability to exist in pairs may contribute to its colonization strategies within host tissues. The ecological role of Escherichia coli O69:H11 str. 08-4661 may be influenced by its host-associated lifestyle, which could involve interactions with other microbial communities in the gastrointestinal tract or other host habitats. This strain's facultative anaerobic metabolism suggests a versatility that may enable it to adapt to fluctuating oxygen levels, further enhancing its survival and ecological success within the host. Understanding these traits provides insight into the physiological capabilities of E. coli O69:H11 str. 08-4661 and its potential interactions within the microbiome.
