Escherichia coli strain NCTC8009

Escherichia coli strain NCTC8009 is a Gram-negative, rod-shaped bacterium that exhibits a facultative anaerobic metabolism, allowing it to thrive in various oxygen conditions. This strain displays mobility due to the presence of flagella and typically forms pairs or single cells. It is classified as mesophilic, with an optimal growth temperature of 37°C. NCTC8009 is found in diverse habitats, primarily associated with hosts, including Homo sapiens (humans), various mammals (e.g., Gallus gallus, Bos taurus, Sus scrofa), and even plants like Solanum lycopersicum (tomato). Its biotic relationship is free-living, indicating its ability to exist independently while still being able to infect a wide range of hosts. This strain is known for its pathogenicity in humans, contributing to several health issues such as urinary tract infections (UTIs), gastrointestinal infections, neonatal meningitis, and septicemia. It is implicated in severe conditions like hemolytic uremic syndrome (HUS), which can lead to renal failure and other systemic complications. The strain's role in foodborne infections and gastrointestinal diseases highlights the public health significance of E. coli. Given its extensive host range and pathogenic potential, E. coli strain NCTC8009 serves as an important model for studying the dynamics of enteric infections and the mechanisms of microbial pathogenesis. Understanding its interactions with various hosts can provide insights into transmission pathways and the development of targeted interventions for preventing E. coli-related diseases.
