Escherichia coli strain 42_rectal

Escherichia coli strain 42_rectal is a Gram-negative, rod-shaped bacterium characterized by its mobility and the presence of flagella. This strain is a facultative anaerobe, thriving optimally at 37°C within a mesophilic temperature range. It has a unique cellular arrangement, typically found in singles or pairs, and possesses a single replicon with a double membrane structure. This strain has a wide range of hosts, including various mammals such as Homo sapiens, Bos taurus, and Sus scrofa, as well as non-mammalian hosts like Solanum lycopersicum and Apis mellifera. Its adaptability to diverse hosts indicates a significant ecological versatility, allowing it to establish in both terrestrial and aquatic environments. E. coli strain 42_rectal is associated with numerous health effects, particularly in humans. It is known to cause urinary tract infections (UTIs), gastrointestinal diseases, and severe conditions such as neonatal meningitis and septicemia. Additionally, it is implicated in foodborne infections, with potential to lead to serious complications like hemolytic uremic syndrome (HUS) and renal failure. The strain exemplifies a complex biotic relationship as it is free-living yet pathogenic in certain contexts. Its ability to inhabit various hosts while also being linked to significant health concerns highlights the dual nature of E. coli as both a commensal and a pathogen. This duality underscores the importance of understanding microbial interactions within host ecosystems, particularly in the context of health and disease management.
