Escherichia coli strain AVC251

Escherichia coli strain AVC251 is a Gram-negative, rod-shaped bacterium characterized by its facultative anaerobic metabolism and mobility, facilitated by the presence of flagella. This strain is mesophilic, with an optimal growth temperature of 37°C, and it can exist in pairs or as single cells. AVC251 is host-associated and exhibits a free-living biotic relationship. It has a diverse range of hosts, including Homo sapiens (humans), Gallus gallus (chickens), Bos taurus (cattle), various mammals, and even plants such as Solanum lycopersicum (tomatoes) and Brassica oleracea var. italica (broccoli). This extensive host range highlights its ecological versatility. Clinically, strain AVC251 is notable for its pathogenicity in humans, being linked to a variety of health effects, including urinary tract infections (UTIs), gastrointestinal infections, and peritonitis, among others. It is associated with severe conditions such as hemolytic uremic syndrome (HUS), neonatal meningitis, and multiple forms of diarrhea, indicating its potential to cause significant health issues. The strain's ability to thrive in various environments and its pathogenic potential underscore the importance of monitoring and managing E. coli infections, particularly in clinical settings. Understanding the ecological role of AVC251 can provide insights into its transmission dynamics and impact on both human health and agricultural systems, especially considering its interactions with livestock and crops.
