Escherichia coli strain ECONIH5

Escherichia coli strain ECONIH5 is a Gram-negative, rod-shaped bacterium that exhibits a facultative anaerobic metabolism, allowing it to thrive in both aerobic and anaerobic environments. This strain is motile, possessing flagella, and typically arranges itself in pairs or as singles. Economically relevant, E. coli strain ECONIH5 has a mesophilic temperature range with an optimal growth temperature of 37°C, reflecting its adaptation to host-associated habitats, particularly within warm-blooded animals. The strain is free-living but has a broad range of hosts, including Homo sapiens, Gallus gallus, Bos taurus, and various other mammals, birds, and even plants. This extensive host range indicates its ecological versatility and potential for transmission across species. E. coli strain ECONIH5 is associated with numerous health issues, notably urinary tract infections (UTIs), gastrointestinal infections, and severe conditions such as septicemia and hemolytic uremic syndrome (HUS). The strain's pathogenicity in humans is particularly concerning, as it is linked to serious health outcomes including neonatal meningitis, renal failure, and foodborne illnesses. The strain contains seven replicons and has a double membrane structure, a characteristic typical of Gram-negative bacteria. The presence of multiple replicons may contribute to its genetic adaptability, facilitating the acquisition of virulence factors. In summary, E. coli strain ECONIH5 plays a significant role in human health and disease, underscoring its importance in microbiology and public health. Its ability to thrive in diverse environments and a wide array of hosts highlights its ecological significance and challenges in disease management.
