Escherichia coli strain NCTC9081

Escherichia coli strain NCTC9081 is a Gram-negative, rod-shaped bacterium that exhibits a facultative anaerobic lifestyle, allowing it to thrive in various environments. This strain is motile and possesses flagella, enabling it to move actively within its host-associated habitats. It is mesophilic, with an optimal growth temperature of 37°C, which aligns with the body temperature of its primary hosts, including Homo sapiens and various animal species such as Gallus gallus (chickens), Bos taurus (cattle), and Canis lupus familiaris (domestic dogs). E. coli NCTC9081 has a single replicon and is characterized by a double membrane structure, typical of Gram-negative bacteria. Its biotic relationships are primarily free-living, allowing it to interact with multiple hosts, including invertebrates like Acanthamoeba and various vertebrates. This strain is associated with a wide range of health effects, particularly in humans. It is known to cause urinary tract infections (UTIs), gastrointestinal infections, and other serious conditions such as neonatal meningitis and septicemia. The strain's pathogenicity highlights its role in clinical settings, particularly related to foodborne infections and complications arising from infections, including renal failure and hemolytic uremic syndrome (HUS). The diverse host range and significant health impacts underscore the ecological and biological importance of E. coli NCTC9081, reflecting its adaptability and potential as a pathogen in both human and animal health contexts.
