Escherichia coli strain U14A

Escherichia coli strain U14A is a Gram-negative, rod-shaped bacterium that exhibits facultative anaerobic respiration, allowing it to thrive in both oxygen-rich and oxygen-poor environments. This strain is motile, possessing flagella, and typically arranges itself in pairs or as single cells. Its optimal growth temperature is 37°C, placing it within the mesophilic range, which is ideal for many host organisms. E. coli U14A has a complex genetic architecture, featuring six replicons and two membranes. It is primarily host-associated, indicating a reliance on various organisms for its ecological niche. This strain has a wide range of potential hosts, including Homo sapiens (humans), Gallus gallus (chickens), Bos taurus (cattle), and many others spanning multiple classes of the animal kingdom, as well as some plants like Solanum lycopersicum (tomatoes) and Brassica oleracea var. italica (broccoli). In terms of health impacts, E. coli U14A is associated with a variety of serious conditions, including urinary tract infections (UTIs), gastrointestinal infections, and neonatal meningitis. Its pathogenicity in humans underscores its role as a significant public health concern, leading to various infections and complications such as hemolytic uremic syndrome (HUS) and septicemia. The ecological insight from E. coli strain U14A's diverse host range suggests its adaptability and potential role in both environmental and clinical microbiomes. This adaptability may contribute to its persistence in various habitats, further complicating efforts to manage infections caused by this strain.
