It is generally encoded by the fliC gene[citation needed] There are 53 identified H antigens, numbered from H1 to H56 (H13 and H22 were not E. coli antigens but from Citrobacter freundii, and H50 was found to be the same as H10). (wikipedia.org)

If E.coli is grown on plates that are rich in lactose, a nutrient for growth, it has been shown that some colonies will develop a mutation that allows them to ferment or metabolize energy from lactose. (emory.edu)
These studies were conducted to determine if actin influences growth and haemolytic activity of E. coli. (microbiologyresearch.org)
Growth of E. coli in the presence of actin resulted in culture supernatant haemolytic activity that was 2.4-, 2.7- and 3.3-fold greater than that of E. coli grown in medium containing BSA, non-supplemented medium, or medium containing heat-denatured actin, respectively. (microbiologyresearch.org)
BACKGROUND: Progenipoietin-4 (ProGP-4) is an E. coli derived chimeric growth factor that activates the human Flt3 and G-CSF receptors. (medscimonit.com)
C. jejuni HPC5 counts invariably declined, whereas C. coli OR12 was capable of immediate growth within the caeca. (nottingham.ac.uk)
Furthermore, a previously developed ADAPT targeting the human epidermal growth factor receptor 2 (HER2) was genetically fused to an improved Horseradish Peroxidase (HRP) variant, thereby combining the idea of tumor-targeted therapy through the ADAPT with the utilization of HRP to enzymatically catalyze the prodrug IAA into its active form. (kth.se)
The survival of a graft in a host, the factors responsible for the survival and the changes occurring within the graft during growth in the host. (lookformedical.com)
The termination of the cell's ability to carry out vital functions such as metabolism, growth, reproduction, responsiveness, and adaptability. (lookformedical.com)
Granulocyte-macrophage colony-stimulating factor (GM-CSF) was first identified as a growth factor due to its ability to induce proliferation and differentiation of bone marrow progenitors into granulocytes and macrophages. (leadgenebio.com)
IL-20 is a hematopoietic growth factor capable of stimulating colony formation by CD34+ multipotential progenitors, but not by other progenitor cells. (peprotech.com)

Exposure of cells to soluble factors that damage cell membranes results in the release of actin into the extracellular spaces. (microbiologyresearch.org)
Cholesterol accessibility or the "ability" of cholesterol to interact with water-soluble molecules at the membrane surface, is modulated by the total cholesterol content and the composition of the membrane. (umass.edu)

Understanding the population structure of pathogenic E. coli is important, since it impacts the effectiveness of molecular epidemiological studies. (eurekaselect.com)

This factor is known mainly because of its chemotactic activity. (topsan.org)

National infectious disease surveillance systems form the foundation of our ability to know and track the routine. (cdc.gov)

It also supports the progression of certain auto immune diseases, possibly through its ability to induce the production and secretion of various pro inflammatory cytokines. (peprotech.com)
Measure by its ability to induce TF-1 cells proliferation. (leadgenebio.com)

These findings highlight that adding Cu to Ti can improve the antibacterial ability of the surface while inhibiting bacterial adherence. (nature.com)

Some shield E.coli from enzymes called lysozymes that break down the outer walls of their cells. (nationalgeographic.com)

Each binder was then examined for their usefulness as a real therapeutic by successfully evaluating its ability to block the interaction of the cytokine and its specific receptor in vitro . (kth.se)

Conventional mice were subjected to broad-spectrum antibiotic treatment for 8 weeks and perorally reassociated with E. coli, L. johnsonii or with a complex murine microbiota by fecal microbiota transplantation (FMT). (uni-kiel.de)
