Escherichia coli strain AVC154

Escherichia coli strain AVC154 is a Gram-negative, rod-shaped bacterium that thrives as a facultative anaerobe, making it adaptable to environments with varying oxygen levels. It exhibits mobility due to the presence of flagella and typically arranges itself in pairs or singles. The optimal temperature for its growth is 37°C, placing it within the mesophilic temperature range. This strain is host-associated and has a diverse range of hosts, including Homo sapiens (humans), Gallus gallus (chickens), Bos taurus (cattle), and several other vertebrates and invertebrates. Its biotic relationship is characterized as free-living, suggesting that while it can dwell within hosts, it also exists independently in the environment. E. coli AVC154 is associated with numerous health effects, particularly in humans, where it is linked to urinary tract infections (UTIs), gastrointestinal infections, and more severe conditions such as neonatal meningitis and hemolytic uremic syndrome (HUS). The strain's pathogenicity underscores its role as a significant human pathogen, contributing to a range of serious health issues including peritonitis, diarrhea, and even colorectal cancer. The broad host range and diverse pathogenic effects of E. coli strain AVC154 indicate its ecological versatility and potential impact on both human health and animal husbandry. Its ability to thrive in various biological niches emphasizes the importance of monitoring and understanding its behavior in both clinical and environmental contexts.
