Escherichia coli strain PNUSAE019581

Escherichia coli strain PNUSAE019581 is a gram-negative, rod-shaped bacterium characterized by its facultative anaerobic metabolism and mobility, attributed to the presence of flagella. This strain is mesophilic, with an optimal growth temperature of 37°C, and typically arranges itself in pairs or singles. PNUSAE019581 is host-associated and free-living, demonstrating a wide range of biological relationships with various hosts, including Homo sapiens, Gallus gallus, Bos taurus, and multiple other vertebrates and invertebrates. This diverse host range highlights its ecological versatility and adaptability. The strain is associated with numerous health effects, particularly in humans, where it can cause serious conditions such as urinary tract infections (UTIs), gastrointestinal infections, and neonatal meningitis. It is implicated in various severe health issues, including septicemia, food poisoning, and hemolytic uremic syndrome (HUS). The presence of E. coli in both healthy and diseased states underscores its dual role in microbiomes, where it can be part of normal flora or a pathogen. Given its significant pathogenic potential, understanding the ecological interactions and health impacts of E. coli strain PNUSAE019581 is crucial. The bacterium’s ability to thrive in diverse environments may contribute to its persistence and spread, making it a critical focus for public health and microbiological research.
