Escherichia coli strain KCJK8357

Escherichia coli strain KCJK8357 is a Gram-negative, rod-shaped bacterium that occurs in pairs or singles and is characterized as a facultative anaerobe. This strain is motile, possessing flagella, and thrives optimally at 37 degrees Celsius, fitting within the mesophilic temperature range. KCJK8357 has a free-living biotic relationship and is associated with a wide range of hosts, including Homo sapiens, Gallus gallus, and various other mammals, birds, and even plants such as Solanum lycopersicum and Brassica oleracea var. italica. The strain is known for its significant health effects in humans, notably causing urinary tract infections (UTIs), gastrointestinal infections, and severe conditions such as neonatal meningitis and hemolytic uremic syndrome (HUS). It has been implicated in various diseases, including peritonitis, diarrhea, and foodborne infections, reflecting its pathogenic potential. With one replicon and two membranes, KCJK8357 exhibits characteristics typical of enteric bacteria. Its ability to thrive in diverse environments and its association with numerous hosts suggest a complex ecological role, particularly in the context of human health and agriculture. The strain's pathogenicity emphasizes the importance of monitoring E. coli in both clinical settings and food safety, given its capacity to cause serious infections and health complications across multiple host species.
