Escherichia coli strain 4/4

Escherichia coli strain 4/4 is a Gram-negative, rod-shaped bacterium characterized as a facultative anaerobe, which allows it to thrive in both aerobic and anaerobic environments. This strain is motile due to the presence of flagella and typically exists in pairs or singles. It operates optimally at 37°C, fitting within the mesophilic temperature range. The strain is known to have six replicons and is surrounded by two membranes, indicating its complex cellular structure. E. coli strain 4/4 is free-living and is associated with a diverse array of hosts, including Homo sapiens (humans), Gallus gallus (chickens), Bos taurus (cattle), and various other vertebrates and invertebrates, including plants such as Solanum lycopersicum (tomato) and Brassica oleracea var. italica (broccoli). Health effects linked to this strain are extensive and include urinary tract infections (UTIs), gastrointestinal infections, neonatal meningitis, and several forms of colitis. It has been implicated in severe conditions such as hemolytic uremic syndrome (HUS), septicemia, and even colorectal cancer. The ecological insight from the data indicates that E. coli strain 4/4 plays a significant role in the health of its host organisms and can be a pathogen in both humans and animals. Its ability to inhabit a wide range of hosts and cause various diseases highlights its importance in both clinical microbiology and public health. Understanding the pathogenicity and host associations of this strain can inform strategies for disease prevention and management.
