Escherichia coli strain KCJK8798

Escherichia coli strain KCJK8798 is a facultative anaerobic, Gram-negative bacterium characterized by its rod shape and mobility, facilitated by the presence of flagella. This strain typically exists in pairs or singles and thrives optimally at 37°C, placing it within the mesophilic temperature range. It possesses a single replicon and has a dual membrane structure, which is typical for Gram-negative organisms. KCJK8798 is primarily host-associated, demonstrating a free-living biotic relationship with a wide array of hosts including Homo sapiens (humans), Gallus gallus (chickens), Bos taurus (cattle), various mammals, and even some plants such as Solanum lycopersicum (tomatoes) and Brassica oleracea var. italica (broccoli). The strain is implicated in numerous health effects, particularly in humans, where it can cause urinary tract infections (UTIs), gastrointestinal infections, and severe conditions such as neonatal meningitis and hemolytic uremic syndrome (HUS). The diverse host range of strain KCJK8798 underscores its ecological versatility and adaptability. This adaptability may contribute to its pathogenic potential in various environments, highlighting the importance of monitoring E. coli strains in both clinical settings and agricultural contexts. The strain’s ability to inhabit multiple hosts and cause significant health issues suggests that it plays a critical role in the dynamics of infectious disease transmission and public health.
