Escherichia coli strain KCJK8899

Escherichia coli strain KCJK8899 is a Gram-negative, rod-shaped bacterium that exhibits a facultative anaerobic oxygen requirement. This strain is characterized by its mobility, facilitated by the presence of flagella, and typically exists in pairs or as single cells. It thrives optimally at 37°C and falls within the mesophilic temperature range. E. coli KCJK8899 is found in host-associated habitats and has a diverse range of hosts, including Homo sapiens, various livestock such as Bos taurus and Sus scrofa, as well as numerous other vertebrates and invertebrates, such as Apis mellifera and Solanum lycopersicum. Its biotic relationship is classified as free-living, indicating its ability to survive independently within its environment. The strain is associated with a wide array of health effects, primarily affecting humans and animals. It is linked to urinary tract infections (UTIs), gastrointestinal infections, and more severe conditions such as septicemia and neonatal meningitis. Other health concerns include foodborne infections, colibacillosis, and complications like hemolytic uremic syndrome (HUS) and chronic mastitis. The pathogenicity of E. coli KCJK8899 underscores its significance in both clinical and ecological contexts, particularly concerning its interaction with human and animal hosts. Its ability to cause a variety of infections highlights the need for continued research and monitoring of E. coli strains in relation to public health and food safety. Understanding its host associations may provide insights into transmission dynamics and potential preventive measures against infections.
