Escherichia coli strain NCTC9702

Escherichia coli strain NCTC9702 is a Gram-negative, rod-shaped bacterium that thrives in host-associated environments, demonstrating a facultative anaerobic metabolism. This strain exhibits mobility, facilitated by the presence of flagella, and has an optimal growth temperature of 37°C, categorizing it as mesophilic. NCTC9702 is characterized by having a single replicon and a double membrane structure. This strain has a diverse range of biotic relationships, as it can be free-living and is associated with multiple hosts, including Homo sapiens, Gallus gallus, Bos taurus, and various other vertebrates and invertebrates. This extensive host range suggests a significant ecological adaptability, allowing NCTC9702 to inhabit different biological niches. Clinically, E. coli NCTC9702 is associated with various health issues, particularly in humans. It is known to cause urinary tract infections (UTIs), gastrointestinal infections, and a wide array of other serious conditions, including neonatal meningitis, septicemia, and hemolytic uremic syndrome (HUS). The strain's pathogenicity highlights its potential impact on public health, particularly in relation to foodborne illnesses and infections that can lead to severe complications. In summary, the ecological versatility and pathogenic potential of E. coli strain NCTC9702 underscore its importance in both health and disease, illustrating the complex interactions between microbial inhabitants and their hosts. The strain's ability to thrive in diverse environments and cause significant health challenges emphasizes the need for ongoing surveillance and research into its behavior and effects on various populations.
