Escherichia coli strain PNUSAE019755

Escherichia coli strain PNUSAE019755 is a Gram-negative, rod-shaped bacterium characterized by its facultative anaerobic metabolism and motility, attributed to the presence of flagella. This strain thrives optimally at a temperature of 37°C, fitting within the mesophilic range. It possesses a single replicon and features a double membrane structure, typical of Gram-negative bacteria. Primarily associated with hosts, this strain has a broad range of potential hosts, including Homo sapiens (humans), Gallus gallus (chickens), Bos taurus (cattle), and various other vertebrates, invertebrates, and plants. Notably, its biotic relationship is classified as free-living, indicating its ability to exist independently, although it often resides within the gastrointestinal tracts of its hosts. E. coli PNUSAE019755 is implicated in a variety of health effects, particularly in humans, where it is associated with conditions such as urinary tract infections (UTIs), gastrointestinal infections, neonatal meningitis, and foodborne illnesses. The strain is known to contribute to severe health issues such as hemolytic uremic syndrome (HUS), septicemia, and even colorectal cancer. The ecological insight derived from these traits highlights the strain's role in both pathogenicity and environmental interactions. Its capacity to inhabit diverse hosts, coupled with its potential to cause significant health issues, underlines the importance of monitoring this strain within clinical and agricultural contexts. Understanding its behavior and impact on health can inform strategies to mitigate its pathogenic effects, especially in environments where human and animal health intersect.
