Escherichia coli strain NCTC9073

Escherichia coli strain NCTC9073 is a Gram-negative, rod-shaped bacterium that exists predominantly in pairs and singles. As a facultative anaerobe, it can thrive in both aerobic and anaerobic environments, with an optimal growth temperature of 37°C, placing it within the mesophilic range. This strain possesses flagella, enabling mobility, and has a biotic relationship characterized as free-living. NCTC9073 is associated with various hosts, including Homo sapiens (humans), Gallus gallus (chickens), Bos taurus (cattle), and several other vertebrates and invertebrates. Its wide host range indicates a versatile ecological role, allowing it to exploit diverse environments. This strain is notably pathogenic to humans, linked to numerous health issues, including urinary tract infections (UTIs), gastrointestinal infections, and severe conditions such as hemolytic uremic syndrome (HUS). It has been implicated in peritonitis, neonatal meningitis, and foodborne infections, showcasing its potential as a significant clinical pathogen. Given its capacity to cause a variety of diseases, including diarrheal diseases and central nervous system infections, NCTC9073 serves as a critical example of how a single microbial strain can impact both human health and veterinary medicine. Its presence across multiple hosts highlights the interconnectedness of ecosystems and the potential for zoonotic transmission of pathogenic strains. Understanding its characteristics can aid in monitoring and controlling infections associated with this strain, emphasizing the importance of further research in both clinical and ecological contexts.
