Escherichia coli strain KS-NP019

Escherichia coli strain KS-NP019 is a Gram-negative, rod-shaped bacterium that is a facultative anaerobe, thriving optimally at 37°C within a mesophilic temperature range. This strain exhibits mobility, characterized by the presence of flagella, and typically arranges itself in pairs or singles. Ecologically, KS-NP019 is associated with a broad range of hosts, including Homo sapiens, various livestock such as Bos taurus and Sus scrofa, as well as other vertebrates and invertebrates like Apis mellifera and Solanum lycopersicum. It demonstrates a free-living biotic relationship, indicating its capacity to exist independently in various environments. Clinically, this strain is significant due to its association with numerous health effects in humans, including urinary tract infections (UTIs), gastrointestinal infections, and severe conditions like hemolytic uremic syndrome (HUS) and neonatal meningitis. The strain has been implicated in foodborne infections and complications related to pregnancy, underscoring its pathogenic potential. The presence of two replicons and two membranes also suggests a complex genetic structure, which may contribute to its adaptability and virulence. Overall, E. coli strain KS-NP019 exemplifies the intricate relationships between microbial pathogens and their hosts, highlighting the importance of understanding microbial diversity and its implications for human health and disease management.
