Escherichia coli strain NCTC9706

Escherichia coli strain NCTC9706 is a Gram-negative, rod-shaped bacterium that exhibits a facultative anaerobic metabolism. It typically resides in host-associated environments, demonstrating mobility due to the presence of flagella. The optimal growth temperature for this strain is 37°C, placing it within the mesophilic temperature range. This strain is notable for its pathogenicity, particularly in humans, where it is associated with a wide range of health effects. These include urinary tract infections (UTIs), gastrointestinal infections, septicemia, and even severe conditions such as hemolytic uremic syndrome (HUS) and neonatal meningitis. The diverse biotic relationships indicate a free-living nature while also being capable of infecting various hosts, including Homo sapiens, Gallus gallus (chickens), and Bos taurus (cattle), among others. The strain is characterized by having a single replicon and two membranes, which is typical for members of the Enterobacteriaceae family. The extensive list of hosts indicates a broad ecological niche, suggesting that E. coli NCTC9706 has adapted to interact with multiple species across various environments. Given its ability to cause significant health issues, understanding the ecological dynamics of this strain can provide insights into its transmission pathways and potential prevention strategies in both human and veterinary medicine.
