Escherichia coli O157:H7 strain FWSEC0004

Escherichia coli O157:H7 strain FWSEC0004 is a pathogenic bacterium primarily associated with various hosts, including Homo sapiens (humans), Bos taurus (cattle), Sus scrofa (pigs), and Oryctolagus cuniculus (rabbits). This strain is classified as a Gram-negative, rod-shaped organism that can exist in pairs or singles. It possesses flagella, which allows for mobility, and is a facultative anaerobe, enabling it to survive in both aerobic and anaerobic environments. The optimal temperature for growth of E. coli O157:H7 FWSEC0004 is 37°C, placing it within the mesophilic temperature range. The bacterium has two replicons and is characterized by a double membrane structure. In terms of its ecological role, it is classified as free-living, indicating its ability to survive independently in various environments. Health effects associated with E. coli O157:H7 FWSEC0004 include diarrhea, hemorrhagic diarrhea, renal failure, anemia, and hemolytic uremic syndrome (HUS), a severe condition that can arise from infection. Given its pathogenic potential and association with multiple hosts, E. coli O157:H7 FWSEC0004 underscores the importance of understanding host interactions and environmental factors that facilitate its transmission and virulence. This strain exemplifies the complex relationships between bacterial pathogens and their animal reservoirs, highlighting the need for continuous monitoring in both clinical and agricultural settings.
