Escherichia coli strain NCTC9434

Escherichia coli strain NCTC9434 is a Gram-negative, rod-shaped bacterium primarily associated with various hosts, including Homo sapiens, domestic animals like Gallus gallus (chickens), Bos taurus (cattle), and multiple other vertebrates and invertebrates. This strain is a facultative anaerobe, indicating its ability to thrive in both aerobic and anaerobic conditions, with an optimal growth temperature of 37°C, characteristic of mesophilic organisms. NCTC9434 possesses flagella, contributing to its mobility, and is identified by a distinctive cell arrangement that includes pairs and singles. It is categorized as free-living, which suggests ecological versatility, allowing it to inhabit diverse environments associated with its numerous hosts. The strain has been implicated in a wide range of health impacts, particularly in humans, where it can cause urinary tract infections (UTIs), gastrointestinal infections, and severe conditions such as neonatal meningitis and hemolytic uremic syndrome (HUS). The extensive pathogenic potential of E. coli NCTC9434 underscores its significance in both human health and veterinary medicine. Its ability to infect various hosts highlights the importance of monitoring and understanding this strain, particularly regarding public health concerns related to foodborne infections and antibiotic resistance. Understanding the ecological interactions of E. coli NCTC9434 can inform strategies for managing infections and preventing disease spread across different populations.
