This Concept Map, created with IHMC CmapTools, has information related to: Answers_compete, iron advantage iron is essential for both bacterial growth and human cell growth, Autoinducer/receptor complexes are able to bind to DNA promoters and activate the transcription of quorum sensing-controlled genes. benefit Individual bacteria within a group are able to benefit from the activity of the entire group., produces surface adhesins that bind to extracellular matrix proteins and polysaccharides surrounding host cell tissue, including fibronectin, collagen, laminin, hyaluronic acid, and elastin; proteases and hyaluronidase then dissolve these components advantages provides food for the bacteria and enabling the bacteria to spread, iron mechanism produce siderophores that trap iron, The production, release, and community-wide sensing of molecules called autoinducers that modulate gene expression in response to the density of a bacterial population process Autoinducers produced by one bacterium cross the membrane of another and bind to receptors in its cytoplasm., iron mechanism bind human iron chelators, The ability to compete for nutrients such as iron often a result of Quorum Sensing, produce toxins and enzymes that kill host cells only when iron concentrations are low in order to release host cell iron advantage obtain iron and other nutrients from host cells, Quorum Sensing definition The production, release, and community-wide sensing of molecules called autoinducers that modulate gene expression in response to the density of a bacterial population, produce toxins and enzymes that kill host cells only when iron concentrations are low in order to release host cell iron example Pseudomonas aeruginosa, The ability to compete for nutrients such as iron mechanisms produce toxins and enzymes that kill host cells only when iron concentrations are low in order to release host cell iron, The ability to compete for nutrients such as iron mechanisms produces surface adhesins that bind to extracellular matrix proteins and polysaccharides surrounding host cell tissue, including fibronectin, collagen, laminin, hyaluronic acid, and elastin; proteases and hyaluronidase then dissolve these components, iron mechanism don't use iron as a cofactor, iron mechanism produce proteases that gegrade human lactoferrin, transferrin, or heme to release the bound iron for capture by bacterial siderophores, Autoinducers produced by one bacterium cross the membrane of another and bind to receptors in its cytoplasm. then Autoinducer/receptor complexes are able to bind to DNA promoters and activate the transcription of quorum sensing-controlled genes., provides food for the bacteria and enabling the bacteria to spread example Staphylococcus aureus, The ability to compete for nutrients such as iron mechanisms synthesizing specific transport systems capable of binding limiting substrates and transporting them into the cell, synthesizing specific transport systems capable of binding limiting substrates and transporting them into the cell example iron, synthesizing specific transport systems capable of binding limiting substrates and transporting them into the cell examples most pathogens and normal flora
