This Concept Map, created with IHMC CmapTools, has information related to: Answers_Contact cell, Many bacteria produce enzymes such as elastases and proteases that degrade the extracellular matrix proteins that surround cells and tissues and make it easier for those bacteria to disseminate within the body. examples Staphylococcus aureus, Streptococcus pyogenes, 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., Using motility and other means to contact host cells and disseminate within a host often a result of Quorum Sensing, Using motility and other means to contact host cells and disseminate within a host enzymes Many bacteria produce enzymes such as elastases and proteases that degrade the extracellular matrix proteins that surround cells and tissues and make it easier for those bacteria to disseminate within the body., enables the pathogen to more readily leave one host and enter new hosts through the fecal-oral route examples gastrointestinal infections, produce toxins that induce diarrhea in the host advantage enables the pathogen to more readily leave one host and enter new hosts through the fecal-oral route, 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., disseminate via the blood infections syphilis, Lyme disease, leptospirosis, Using motility and other means to contact host cells and disseminate within a host motility flagella and chemotaxis, swim through mucus towards mucosal surfaces infections gastrointestinal, respiratory, and urogenital infections, syphilis, Lyme disease, leptospirosis pathogenesis enter the lymphatics and bloodstream and disseminate to other body sites, Using motility and other means to contact host cells and disseminate within a host toxins produce toxins that induce diarrhea in the host, gastrointestinal, respiratory, and urogenital infections examples Helicobacter pylori, Escherichia coli, Pseudomonas aeruginosa, 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, 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., flagella and chemotaxis advantage swim through mucus towards mucosal surfaces, syphilis, Lyme disease, leptospirosis examples Treponema pallidum, Borrelia burgdorferi, Leptospira interrogans, flagella and chemotaxis advantage disseminate via the blood
