Escherichia coli strain KCJK8755

Escherichia coli strain KCJK8755 is a Gram-negative, rod-shaped bacterium that is facultatively anaerobic, thriving optimally at 37°C within a mesophilic temperature range. Its cellular arrangement includes pairs and singles, and it possesses flagella, indicating motility. This strain has a single replicon and is characterized by a double membrane structure. E. coli KCJK8755 is host-associated, exhibiting a free-living biotic relationship. It has a diverse range of potential hosts, including Homo sapiens (humans), Gallus gallus (chickens), Bos taurus (cattle), and various other mammals, birds, and even plants such as Solanum lycopersicum (tomatoes) and Brassica oleracea var. italica (broccoli). This wide host range highlights its ecological versatility and adaptability. The strain is associated with numerous health effects, particularly in humans, where it can cause urinary tract infections (UTIs), gastrointestinal infections, neonatal meningitis, and more severe conditions such as septicemia and hemolytic uremic syndrome (HUS). Its pathogenicity is predominantly recognized in human hosts, making it a significant concern in medical microbiology. The ecological presence of E. coli KCJK8755 in various hosts underscores its role in both health and disease, emphasizing the importance of monitoring this strain in clinical and environmental settings. Its ability to inhabit diverse environments and cause a range of diseases illustrates the complex interactions between microorganisms and their hosts, highlighting the need for ongoing research into its pathogenic mechanisms and ecological impacts.
