Escherichia coli strain FWSEC0544

Escherichia coli strain FWSEC0544 is a Gram-negative, rod-shaped bacterium that exhibits mobility due to the presence of flagella. It is classified as a facultative anaerobe, allowing it to thrive in both aerobic and anaerobic environments. This strain is mesophilic, with an optimal growth temperature of 37°C, and typically exists in pairs or singles. FWSEC0544 is a free-living organism that has a diverse range of hosts, including various species within Homo sapiens, Gallus gallus, Bos taurus, and many others across different taxonomic groups such as Metazoa, Mammalia, and Aves. Its ability to associate with a wide array of hosts underscores its ecological versatility. This strain of E. coli is notably pathogenic to humans and is linked to a range of health effects, including urinary tract infections (UTIs), gastrointestinal infections, and serious conditions such as neonatal meningitis and hemolytic uremic syndrome (HUS). These associations highlight the strain's potential impact on human health, particularly in vulnerable populations such as neonates. The diverse pathogenic potential of FWSEC0544 emphasizes the ecological importance of E. coli as both a commensal and pathogenic organism within its host-associated habitats. It illustrates the complex interplay between microbial species and their hosts, raising awareness about the need for continued research and monitoring of such strains in public health contexts.
