Escherichia coli strain NCTC9044

Escherichia coli strain NCTC9044 is a Gram-negative, rod-shaped bacterium that exhibits a facultative anaerobic metabolism, enabling it to thrive in both aerobic and anaerobic environments. This strain is motile, possessing flagella, and typically exists in pairs or singly. NCTC9044 is classified as mesophilic, with an optimal growth temperature of 37°C. The strain is host-associated and plays a significant role in various biotic relationships, being free-living while also colonizing a diverse range of hosts, including Homo sapiens, Gallus gallus, Bos taurus, and several other vertebrates and invertebrates. Due to its broad host range, E. coli NCTC9044 can contribute to various health effects, particularly in humans, where it is implicated in urinary tract infections (UTIs), gastrointestinal infections, and severe conditions such as neonatal meningitis and hemolytic uremic syndrome (HUS). The strain's pathogenicity is notable in humans, causing a spectrum of diseases, including diarrhea, peritonitis, and septicemia. It is linked to both foodborne infections and clinical conditions, such as renal failure and colorectal cancer. The ecological insight into E. coli NCTC9044 highlights its dual role in health and disease, underscoring the importance of this bacterium in both microbial ecology and clinical microbiology. Understanding its pathogenic mechanisms and host interactions can aid in developing strategies to mitigate its health impacts, particularly in susceptible populations.
