Escherichia coli strain AR_0067

Escherichia coli strain AR_0067 is a Gram-negative, rod-shaped bacterium that demonstrates facultative anaerobic metabolism and exhibits mobility due to the presence of flagella. It is primarily found in host-associated habitats, indicating its adaptation to living within various organisms. The optimal growth temperature for this strain is 37°C, placing it within the mesophilic temperature range. This strain has a complex biotic relationship, being free-living yet associated with a diverse array of hosts, including Homo sapiens (humans), Gallus gallus (chickens), Bos taurus (cattle), and other mammals, birds, and even plants like Solanum lycopersicum (tomato). Such a broad host range may contribute to its ecological versatility and potential for transmission across species. E. coli AR_0067 is notable for its pathogenicity in humans, linked to a variety of health issues including urinary tract infections (UTIs), gastrointestinal infections, and more severe conditions such as neonatal meningitis and hemolytic uremic syndrome (HUS). These health effects highlight the strain's role in both clinical and environmental contexts, emphasizing its relevance in public health. Moreover, the presence of multiple replicons within its genetic structure suggests a potential for genetic adaptability, which may enhance its ability to survive and proliferate in various environments and hosts. Understanding the pathogenic traits and ecological relationships of E. coli strain AR_0067 is crucial for addressing its impact on health, particularly in terms of preventing and managing infections it may cause.
