Escherichia coli strain KCJK8666

Escherichia coli strain KCJK8666 is a Gram-negative, rod-shaped bacterium that can exist in pairs or as single cells. It is classified as a facultative anaerobe, indicating its ability to 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, allowing for motility, and is characterized by a biotic relationship as free-living. KCJK8666 is associated with a variety of hosts, including Homo sapiens, various domestic animals (e.g., Gallus gallus, Bos taurus, Sus scrofa), and a range of other organisms such as Acanthamoeba, Apis mellifera, and even some plants like Solanum lycopersicum. This diverse host range suggests that KCJK8666 may have significant ecological interactions, potentially acting as a pathogen across multiple species. The strain is notably pathogenic to humans, contributing to a wide array of health issues, including urinary tract infections (UTIs), gastrointestinal infections, neonatal meningitis, and severe conditions such as hemolytic uremic syndrome (HUS) and septicemia. The presence of KCJK8666 in various hosts highlights its potential role in zoonotic transmission and foodborne infections, underscoring its importance in public health. Understanding the traits and pathogenicity of E. coli strain KCJK8666 is crucial for developing strategies to mitigate its health impacts, particularly in the context of food safety and disease prevention in both humans and animals.
