Escherichia coli strain CRE1540

Escherichia coli strain CRE1540 is a Gram-negative, rod-shaped bacterium that is characterized as a facultative anaerobe, capable of thriving in both aerobic and anaerobic environments. This strain is notable for its mobility, attributed to the presence of flagella, and it typically exists in pairs or singles. The optimal growth temperature for CRE1540 is 37°C, placing it within the mesophilic range. CRE1540 is primarily host-associated, exhibiting a diverse range of biotic relationships with various hosts, including Homo sapiens, Gallus gallus, Bos taurus, and many others, spanning multiple taxa such as mammals, birds, and reptiles. This strain possesses three replicons and two membranes, which are characteristic of its complex genetic structure. The health implications of E. coli strain CRE1540 are significant, as it is associated with numerous pathogenic effects in humans. It can cause urinary tract infections (UTIs), gastrointestinal infections, neonatal meningitis, and various other serious health conditions such as septicemia and hemolytic uremic syndrome (HUS). The presence of this strain in various hosts indicates its adaptability and potential for cross-species transmission, which could pose risks for zoonotic infections. Ecologically, the versatility of E. coli strain CRE1540 in inhabiting diverse environments and its ability to affect multiple host species highlight its role in microbial ecosystems. Its pathogenicity and presence in both domestic and wild animals suggest that monitoring this strain is crucial for public health and animal health management.
