Escherichia coli strain KCJK8198

Escherichia coli strain KCJK8198 is a Gram-negative, rod-shaped bacterium that exhibits a facultative anaerobic metabolism, enabling it to thrive in both aerobic and anaerobic environments. This strain is characterized by its mobility, facilitated by the presence of flagella, and typically exists in pairs or singles. It has a mesophilic temperature range, with an optimal growth temperature of 37°C. KCJK8198 is host-associated, demonstrating a diverse range of biotic relationships with numerous hosts, including Homo sapiens (humans), Gallus gallus (chickens), Bos taurus (cattle), and various other mammals, birds, and even plants such as Solanum lycopersicum (tomato) and Brassica oleracea var. italica (broccoli). This extensive host range suggests that KCJK8198 may play significant roles in various ecological niches, including both free-living and pathogenic contexts. The strain is linked to numerous health effects, primarily in humans, including urinary tract infections (UTIs), gastrointestinal infections, and more severe conditions such as neonatal meningitis and hemolytic uremic syndrome (HUS). The pathogenicity of KCJK8198 appears to be a critical factor in its interactions with host organisms, particularly in causing diseases that affect the urinary and gastrointestinal tracts, which can lead to significant health issues. The ecological insight from the diverse host range and the associated health impacts highlights the importance of monitoring E. coli strains like KCJK8198, as they can serve as indicators of environmental health and food safety, given their potential to cause foodborne illnesses and other infections. Understanding the dynamics of such strains is crucial for public health and disease prevention strategies.
