Escherichia coli strain SLK172

Escherichia coli strain SLK172 is a Gram-negative, rod-shaped bacterium that exhibits a facultative anaerobic metabolism. This strain can be found in pairs or singles and possesses flagella, allowing for mobility. It thrives optimally at 37°C and is classified as mesophilic, indicating it favors moderate temperature ranges for growth. E. coli SLK172 is predominantly host-associated and has a diverse range of hosts, including Homo sapiens (humans), Gallus gallus (chickens), Bos taurus (cattle), and various other mammals, birds, and even some plants like Solanum lycopersicum (tomato) and Brassica oleracea var. italica (broccoli). This extensive host range suggests that E. coli SLK172 can adapt to various biological environments, making it a versatile organism in different ecological niches. The strain is implicated in several health issues, particularly in humans, including urinary tract infections (UTIs), gastrointestinal infections, and more severe conditions like neonatal meningitis and hemolytic uremic syndrome (HUS). These health effects underline the pathogenic potential of E. coli SLK172, which can result in significant clinical consequences. In summary, the ability of E. coli SLK172 to inhabit various hosts and its association with numerous health complications highlight its ecological significance and pathogenic capacity. Understanding this strain's biology and interactions with different hosts can provide insights into its role in health and disease, emphasizing the importance of monitoring such versatile microorganisms in clinical and environmental contexts.
