Escherichia coli O111:H11 str. CVM9455 ECO9455_99

Escherichia coli O111:H11 str. CVM9455 (ECO9455_99) is a Gram-negative, rod-shaped bacterium that typically exists in pairs or as single cells. This strain is part of the diverse E. coli species, which are primarily found in host-associated environments. It exhibits facultative anaerobic metabolism, allowing it to thrive in both aerobic and anaerobic conditions. The optimal growth temperature for this strain is 37°C, aligning with the physiological temperature of its mammalian hosts. As a member of the Enterobacteriaceae family, E. coli O111:H11 str. CVM9455 is likely adapted to the intestinal milieu of warm-blooded animals, where it can exploit various nutrient sources available in the gut. The ability to grow in the presence or absence of oxygen suggests a versatile metabolic capability, which may facilitate its survival in fluctuating environmental conditions within the host. Such adaptability is a common trait among enteric bacteria, enabling them to colonize and persist in the complex gastrointestinal ecosystem. Furthermore, the specific strain designation, O111:H11, indicates the presence of particular surface antigens, which could play a role in its interactions within the host environment, although details regarding its pathogenic potential or specific ecological roles require further investigation. Overall, E. coli O111:H11 str. CVM9455 exemplifies the adaptability and ecological specialization of enteric bacteria within host-associated habitats.
