Escherichia coli strain PF9285

Escherichia coli strain PF9285 is a Gram-negative, rod-shaped bacterium that exhibits a facultative anaerobic metabolism, allowing it to thrive in diverse environments. This strain is capable of mobility due to the presence of flagella and typically exists in pairs or singles. It is mesophilic, with an optimal growth temperature of 37°C, which is consistent with the human body temperature, indicating its adaptation to host-associated habitats. PF9285 interacts with a wide range of hosts, including Homo sapiens, various domestic animals such as Gallus gallus (chickens), Bos taurus (cattle), and Canis lupus familiaris (dogs), as well as plants like Solanum lycopersicum (tomatoes) and Brassica oleracea var. italica (broccoli). This extensive host range suggests ecological versatility and potential for cross-species transmission. In terms of health impacts, E. coli strain PF9285 is associated with numerous infections, including urinary tract infections (UTIs), gastrointestinal diseases, peritonitis, and neonatal meningitis. The strain has been implicated in severe health conditions such as hemolytic uremic syndrome (HUS) and septicemia, highlighting its pathogenic potential in humans and other hosts. The presence of multiple replicons may contribute to its adaptability and resistance mechanisms. The ability of PF9285 to thrive in various host organisms reflects its ecological role as a free-living bacterium, capable of participating in complex microbial communities. Its pathogenicity underscores the importance of monitoring such strains in both clinical and environmental contexts, as they can significantly impact public health and animal welfare.
