Escherichia coli strain KCJK8509

Escherichia coli strain KCJK8509 is a Gram-negative, rod-shaped bacterium that exhibits a facultative anaerobic lifestyle, allowing it to thrive in both aerobic and anaerobic environments. This strain is characterized by its capability to move due to the presence of flagella and typically arranges itself in pairs or singles. It has been identified as a mesophilic organism with an optimal growth temperature of 37°C. The habitat of KCJK8509 is primarily host-associated, indicating a close relationship with various hosts, including Homo sapiens, Gallus gallus, and Bos taurus, among others. This strain is free-living, suggesting it can exist independently of its hosts as well. The extensive list of hosts includes a diverse range of taxa, such as mammals, birds, and even some plant species like Solanum lycopersicum and Brassica oleracea var. italica. KCJK8509 is notable for its significant health implications, being associated with numerous conditions such as urinary tract infections (UTIs), gastrointestinal infections, neonatal meningitis, and foodborne illnesses. The strain is linked to severe health outcomes, including hemolytic uremic syndrome (HUS) and septicemia, highlighting its pathogenic potential in humans and other animals. The ecological insight from the traits of KCJK8509 reflects its adaptability and versatility, allowing it to thrive in varied environments and interact with multiple hosts. This adaptability not only enhances its survival but also underscores the importance of monitoring such strains due to their implications for public health and animal health.
