Escherichia coli strain 34VL

Escherichia coli strain 34VL is a Gram-negative, rod-shaped bacterium that exhibits mobility due to the presence of flagella. It is a facultative anaerobe, thriving optimally at 37°C and classified as mesophilic. This strain is characterized by its ability to exist in pairs or singles, and it possesses a single replicon and two membranes, typical of Gram-negative bacteria. E. coli strain 34VL is primarily host-associated, exhibiting a wide range of biotic relationships with various hosts, including Homo sapiens, Gallus gallus, Bos taurus, and many others across different taxa. This wide host range highlights its ecological versatility, allowing it to thrive in diverse environments, from mammals to plants and even some invertebrates. Clinically, strain 34VL is associated with numerous health effects, including urinary tract infections (UTIs), gastrointestinal infections, and neonatal meningitis, among others. Its pathogenic potential is significant, as it can lead to severe conditions such as hemolytic uremic syndrome (HUS), septicemia, and even colorectal cancer. The strain's ability to cause a variety of infections, including foodborne illnesses and complications related to pregnancy, underscores its importance as a pathogen in both human and veterinary medicine. The ecological insight from E. coli strain 34VL's diverse host associations and pathogenicity suggests that it plays a crucial role in the microbiome dynamics of various species. Its adaptability and potential for virulence highlight the need for ongoing surveillance and research to better understand its impact on health and disease across different hosts.
