Escherichia coli strain KCJK8819

Escherichia coli strain KCJK8819 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 motility, facilitated by the presence of flagella, and it typically exists as single cells or in pairs. The optimal growth temperature for KCJK8819 is 37°C, categorizing it as mesophilic. The habitat of strain KCJK8819 is primarily host-associated, with a wide range of hosts including Homo sapiens, Gallus gallus, Bos taurus, various mammals, birds, and even plants like Solanum lycopersicum. This extensive host range indicates its adaptability and potential impact on both animal and human health. KCJK8819 is associated with numerous health effects, particularly in humans, where it is linked to various conditions such as urinary tract infections (UTIs), gastrointestinal infections, and neonatal meningitis. The strain can also contribute to severe outcomes like hemolytic uremic syndrome (HUS) and peritonitis. Its pathogenicity in humans highlights its clinical significance, as it can lead to both localized and systemic infections. The free-living biotic relationship of KCJK8819 suggests that it not only exists within hosts but may also reside in the environment, potentially influencing ecological dynamics. Understanding the pathogenic traits and host interactions of this strain is crucial for addressing the public health challenges it poses, particularly in the context of foodborne infections and antibiotic resistance.
