Escherichia coli strain SL3

Escherichia coli strain SL3 is a Gram-negative, rod-shaped bacterium typically found in pairs or singles. This strain is classified as a facultative anaerobe, allowing it to thrive in both oxygen-rich and oxygen-poor environments. It possesses flagella, which contribute to its mobility, and it is mesophilic, with an optimal growth temperature of 37°C. E. coli SL3 is associated with a diverse range of hosts, including Homo sapiens (humans), Gallus gallus (chickens), Bos taurus (cattle), and many others, indicating its widespread ecological presence across different species, including mammals, birds, and even some plants like Solanum lycopersicum (tomato) and Brassica oleracea var. italica (broccoli). As a free-living organism, it interacts with various hosts, potentially influencing their health. The strain is notably pathogenic, linked to a variety of health effects in humans, such as urinary tract infections (UTIs), gastrointestinal infections, and severe conditions like hemolytic uremic syndrome (HUS) and neonatal meningitis. Its ability to cause both intestinal and extraintestinal diseases highlights its significant role in clinical microbiology and public health. The diverse host range and pathogenic potential of E. coli SL3 underscore the ecological and health implications of this strain. It exemplifies how a single microbial species can inhabit numerous environments and interact with various hosts, leading to significant health outcomes, particularly in human populations. Understanding such relationships is crucial for developing strategies to manage infections and mitigate their impact on health.
