Escherichia coli strain NCTC8500

Escherichia coli strain NCTC8500 is a Gram-negative, rod-shaped bacterium that displays a facultative anaerobic metabolism, allowing it to thrive in both aerobic and anaerobic environments. This strain is mobile, possessing flagella that facilitate its movement. It is typically found in host-associated habitats and exhibits a mesophilic temperature range, with an optimal growth temperature of 37°C. E. coli NCTC8500 has a biotic relationship characterized as free-living, and it can inhabit a wide variety of hosts, including Homo sapiens (humans), Gallus gallus (chickens), Bos taurus (cattle), and numerous other vertebrates and invertebrates. Its pathogenic potential in humans is significant, as it is associated with a range of health effects. These include urinary tract infections (UTIs), gastrointestinal infections, and severe conditions such as neonatal meningitis and hemolytic uremic syndrome (HUS). The strain is implicated in diverse clinical manifestations, including diarrhea, septicemia, and even colorectal cancer, highlighting its role as a prominent pathogen in both foodborne and nosocomial infections. Understanding E. coli NCTC8500's complex interactions with various hosts and its pathogenic capabilities underscores the ecological and health implications of this strain. Its ability to infect multiple species suggests a significant role in the epidemiology of enteric diseases and highlights the importance of monitoring such pathogens in both human health and veterinary contexts. This strain's adaptability and pathogenicity exemplify the intricate relationships between bacteria and their hosts in ecological systems.
