Escherichia coli strain FDAARGOS_497

Escherichia coli strain FDAARGOS_497 is a Gram-negative, rod-shaped bacterium characterized by its facultative anaerobic metabolism, enabling it to thrive in both aerobic and anaerobic environments. This strain is motile, possessing flagella, and typically arranges itself in singles or pairs. It is mesophilic, with an optimal growth temperature of 37°C, which aligns with its associations with a variety of hosts, primarily Homo sapiens, but also including Gallus gallus, Bos taurus, and other vertebrates and invertebrates. This strain has a complex biotic relationship, being free-living and associated with multiple hosts across various taxa, including mammals, birds, and even plants like Solanum lycopersicum and Brassica oleracea var. italica. The presence of four replicons and two membranes suggests a robust genetic framework that may contribute to its adaptability and pathogenic potential. FDAARGOS_497 is known for its association with a wide range of health effects, including urinary tract infections (UTIs), gastrointestinal infections, and severe conditions such as septicemia and hemolytic uremic syndrome (HUS). This extensive pathogenicity indicates its significance in both human health and veterinary medicine, highlighting its role in foodborne illnesses and infections in livestock. The diverse host range and pathogenic traits of E. coli strain FDAARGOS_497 underscore its ecological versatility and potential impact on health across species, necessitating continued surveillance and research to understand its dynamics in various environments and its implications for public health.
