Escherichia coli strain CV839-15

Escherichia coli strain CV839-15 is a Gram-negative, rod-shaped bacterium that exhibits a facultative anaerobic metabolism and is capable of mobility due to the presence of flagella. This strain has a mesophilic temperature range, with an optimal growth temperature of 37°C, and typically exists in pairs or singles within a host-associated habitat. It is characterized by having two replicons and two membranes, which are common features of many bacteria. CV839-15 has a diverse range of hosts, including Homo sapiens (humans), various livestock such as Bos taurus (cattle) and Sus scrofa (pigs), as well as birds, primates, and even certain plants like Solanum lycopersicum (tomatoes). The strain is free-living in its ecological niche, suggesting its adaptability to different environments and hosts. Clinically, E. coli CV839-15 is associated with a variety of health effects, predominantly in humans. It is known to cause urinary tract infections (UTIs), gastrointestinal infections, and more severe conditions such as septicemia and meningitis. Its pathogenicity highlights its role as a significant opportunistic pathogen capable of inducing a range of diseases, including diarrhea and colibacillosis. The strain's broad host range and association with serious health complications illustrate its ecological role as both a commensal and a pathogen. This duality emphasizes the importance of understanding host-bacteria interactions and the potential for E. coli strains to impact health across various species, including humans and livestock.
