Escherichia coli strain JL_F20_1

Escherichia coli strain JL_F20_1 is a Gram-negative, rod-shaped bacterium that is facultatively anaerobic and exhibits mobility due to the presence of flagella. This strain is primarily host-associated, having been identified in a variety of hosts, including Homo sapiens (humans), Gallus gallus (chickens), and Bos taurus (cattle), among others. It exists in pairs or singles and thrives optimally at 37°C, indicating that it is mesophilic in nature. The strain has a single replicon and is characterized by a double-membrane structure, typical of Gram-negative bacteria. JL_F20_1 has been implicated in a wide range of health effects, particularly in humans, where it is associated with urinary tract infections (UTIs), gastrointestinal infections, and severe conditions such as hemorrhagic colitis and hemolytic uremic syndrome (HUS). These health concerns highlight its pathogenic potential, particularly in causing urinary and intestinal diseases. Ecologically, the diverse range of hosts associated with JL_F20_1 suggests that it plays a versatile role in various environments, affecting both animal and human health. Its free-living nature indicates that it can survive outside of a host, potentially leading to foodborne infections and outbreaks. The ability to thrive in multiple hosts and its associated health implications underscore the importance of monitoring and understanding this strain within both clinical and ecological contexts.
