Escherichia coli strain NCTC9075

Escherichia coli strain NCTC9075 is a Gram-negative, rod-shaped bacterium that exhibits a facultative anaerobic lifestyle, allowing it to thrive in various oxygen conditions. This strain is motile and possesses flagella, contributing to its ability to inhabit diverse environments, often associated with hosts such as Homo sapiens, Bos taurus, and Sus scrofa, among others. Notably, it has a single replicon and two membranes, characteristic of its cellular structure. NCTC9075 is mesophilic, with an optimal growth temperature of 37°C, reflecting its adaptation to warm-blooded hosts. It has been implicated in a range of health effects, primarily associated with urinary tract infections (UTIs), gastrointestinal infections, and more severe conditions such as neonatal meningitis and hemolytic uremic syndrome (HUS). This strain is known to cause significant clinical diseases, including peritonitis, diarrhea, and sepsis, highlighting its pathogenic potential in humans and other animals. The extensive list of hosts indicates a broad ecological niche, suggesting that E. coli NCTC9075 can engage in various biotic relationships, including free-living states. Its presence in diverse species, from mammals to birds and even plants like Solanum lycopersicum, underscores its adaptability. This adaptability may facilitate the strain's transmission and survival across different environments, making it a significant concern in public health and veterinary medicine. The strain's role in serious health complications emphasizes the need for ongoing research and monitoring to mitigate its impact on human and animal health.
