Escherichia coli strain UMB6454

Escherichia coli strain UMB6454 is a Gram-negative, rod-shaped bacterium that exhibits a facultative anaerobic lifestyle, capable of growth in both aerobic and anaerobic environments. Its optimal growth temperature is 37°C, placing it firmly within the mesophilic temperature range. UMB6454 can exist as single cells or in pairs, and it possesses flagella, enabling mobility. This strain is notably associated with a diverse range of hosts, including Homo sapiens (humans), Gallus gallus (chickens), Bos taurus (cattle), and several other mammals, birds, and even plants such as Solanum lycopersicum (tomatoes) and Brassica oleracea var. italica (broccoli). It demonstrates a free-living biotic relationship, further emphasizing its adaptability across various ecological niches. E. coli UMB6454 is associated with numerous health effects, particularly urinary tract infections (UTIs), gastrointestinal infections, and severe conditions such as neonatal meningitis and hemolytic uremic syndrome (HUS). Its pathogenicity in humans highlights its role as a significant opportunistic pathogen, capable of causing a wide range of diseases, from mild diarrhea to severe systemic infections. The diverse host range and the strain's ability to thrive in various environments suggest a robust ecological adaptability, which may facilitate its transmission and persistence in different settings. This adaptability underscores the importance of monitoring E. coli strains like UMB6454, as they can impact both human health and agricultural systems through foodborne infections and animal disease.
