Escherichia coli strain KCJK8399

Escherichia coli strain KCJK8399 is a Gram-negative, rod-shaped bacterium that exhibits mobility through the presence of flagella. As a facultative anaerobe, it can thrive in both aerobic and anaerobic environments, with an optimal growth temperature of 37°C, placing it within the mesophilic range. This strain is associated with a variety of hosts, including Homo sapiens, Gallus gallus, Bos taurus, various mammals, and even plants such as Solanum lycopersicum and Brassica oleracea var. italica. The strain has been identified as free-living, which allows it to inhabit diverse ecological niches, particularly those associated with warm-blooded vertebrates. E. coli KCJK8399 is linked to significant health impacts in humans, including urinary tract infections (UTIs), gastrointestinal infections, and more severe conditions such as neonatal meningitis and hemolytic uremic syndrome (HUS). The strain's pathogenicity highlights its ability to cause a wide array of clinical conditions, ranging from mild diarrhea to severe septicemia. The extensive list of potential hosts indicates that E. coli KCJK8399 plays a role in both health and disease across multiple species. This bacterium's versatility and pathogenic potential underscore its ecological significance, as it can affect not only individual host health but also broader population dynamics and disease transmission within ecosystems. The presence of E. coli in both human and animal hosts further emphasizes its importance in public health and microbiological studies.
