Escherichia coli strain FWSEC0265

Escherichia coli strain FWSEC0265 is a Gram-negative, rod-shaped bacterium that exhibits mobility due to the presence of flagella. This strain is classified as a facultative anaerobe, allowing it to thrive in both aerobic and anaerobic environments, which can be critical for its survival in diverse habitats. FWSEC0265 is primarily host-associated, having been found in a variety of hosts, including Homo sapiens, Gallus gallus, Bos taurus, and various other mammals, birds, and even invertebrates such as mollusks and insects. The strain has a mesophilic temperature range, with an optimal growth temperature of 37°C, which aligns with the average body temperature of many warm-blooded hosts. Its biotic relationship is described as free-living, suggesting it can exist independently of its hosts, though it is also noted for its pathogenicity in humans. FWSEC0265 is associated with a wide array of health effects, including urinary tract infections (UTIs), gastrointestinal infections, and serious conditions like neonatal meningitis and hemolytic uremic syndrome (HUS). The extensive list of potential health impacts indicates that FWSEC0265 can adapt to various environments and hosts, possibly contributing to its role in foodborne illnesses and clinical infections. The presence of this strain in multiple host species emphasizes the ecological significance of E. coli in both human health and broader environmental contexts, as it reflects the interconnectedness of microbial life and host interactions across different ecosystems.
