Escherichia coli strain VL119

Escherichia coli strain VL119 is a Gram-negative, rod-shaped bacterium that exhibits 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 pairs or singles. Its optimal growth temperature is 37°C, categorizing it as mesophilic. E. coli VL119 is primarily host-associated, with a diverse range of hosts that include various mammals, birds, and even plants. Notable hosts encompass Homo sapiens, Gallus gallus, Bos taurus, and several others, indicating its ecological versatility. This strain demonstrates a biotic relationship as a free-living organism, which can inhabit various environments within its host organisms. Importantly, E. coli VL119 is associated with numerous health effects, particularly in humans. It is linked to urinary tract infections (UTIs), gastrointestinal infections, and severe conditions such as neonatal meningitis and hemolytic uremic syndrome (HUS). The bacterium can also cause foodborne infections and is implicated in various inflammatory diseases. The wide host range and the significant health impacts of E. coli VL119 highlight its ecological role as both a commensal organism and a potential pathogen. Its presence in diverse environments and hosts suggests a complex interplay within microbial communities, emphasizing the need for ongoing research to understand its pathogenic mechanisms and implications for public health.
