Escherichia coli strain MEZEC54 91

Escherichia coli strain MEZEC54 91 is a Gram-negative, rod-shaped bacterium that demonstrates mobility through the presence of flagella. As a facultative anaerobe, it can thrive in both aerobic and anaerobic environments, with an optimal growth temperature of 37°C, classifying it as mesophilic. This strain is associated with a wide array of hosts, including Homo sapiens, Gallus gallus, Bos taurus, among others, indicating its versatility and adaptability in various biological niches. In terms of pathogenicity, E. coli MEZEC54 91 is known to be a human pathogen, implicated in numerous health conditions. These include urinary tract infections (UTIs), gastrointestinal infections, neonatal meningitis, and more severe complications such as hemolytic uremic syndrome (HUS) and septicemia. The strain's association with both free-living and host-associated environments highlights its ecological role and potential for transmission across different species, including mammals, birds, and even plants. The extensive list of health effects linked to this strain underscores its public health significance, particularly in the context of foodborne infections and urinary tract infections. As E. coli is a common inhabitant of the intestinal tract of humans and animals, understanding the traits of strain MEZEC54 91 can provide insights into the mechanisms underlying its pathogenicity and its interactions with various hosts. This knowledge is crucial for developing strategies to manage infections and mitigate risks associated with this versatile bacterium.
