Escherichia coli strain AR_0085

Escherichia coli strain AR_0085 is a Gram-negative, rod-shaped bacterium that displays a facultative anaerobic metabolism, allowing it to thrive in both aerobic and anaerobic environments. This strain is motile, possessing flagella, and typically arranges itself in singles or pairs. It is mesophilic, with an optimal growth temperature of 37°C, which aligns with the human body temperature, indicating its adaptation to host-associated habitats. E. coli AR_0085 is known to have a wide range of hosts, including Homo sapiens, various mammals (e.g., Bos taurus, Sus scrofa), avian species (e.g., Gallus gallus, Meleagris gallopavo), and even some plants (e.g., Solanum lycopersicum). This extensive host range underscores its ecological versatility and potential for transmission across different species. The strain is implicated in numerous health issues, particularly in humans, where it is associated with urinary tract infections (UTIs), gastrointestinal infections, and more severe conditions such as neonatal meningitis and hemolytic uremic syndrome (HUS). Its pathogenicity is evident in its ability to cause diverse clinical manifestations, including diarrhea, septicemia, and colibacillosis. The presence of two replicons and two membranes indicates a complex genetic structure typical of many E. coli strains. Given its pathogenic potential and ability to inhabit a broad range of hosts, E. coli strain AR_0085 highlights the importance of understanding microbial interactions within ecosystems and the potential health risks posed by zoonotic transmission.
