This Concept Map, created with IHMC CmapTools, has information related to: Answers_Colonization_part1, cell wall adhesins ???? adhesins fit host cell receptors, adhesive tips fit host cell receptors examples Neisseria gonorrhoeae, Neisseria meningitidis, Escherichia coli, Vibrio cholerae, gastrointestinal, respiratory, and urogenital infections examples Helicobacter pylori, Escherichia coli, Pseudomonas aeruginosa, swim through mucus towards mucosal surfaces infections gastrointestinal, respiratory, and urogenital infections, certain spirochetes pathogenesis enter the lymphatics and bloodstream and disseminate to other body sites, flagella and chemotaxis advantage swim through mucus towards mucosal surfaces, enable bacteria to adhere, colonize, and resist physical removal mechanism biofilm-producing capsule, causes the host cell to release digestive enzymes that enable the spirochete with its corkscrewing motility to penetrate host cell membrane,invade and leave blood vessels, and dessiminate to other locations examples Treponema pallidum, Borrelia burgdorferi, Bacterial Colonization of the Host mechanism the ability to invade host cells, motility and invasins ???? spiorochetes, certain spirochetes examples Treponema pallidum, Borrelia burgdorferi, iron mechanism produce exotoxins that kill host cells only when iron concentrations are low in order to release host cell iron, using motility and other means to contact host cells motility flagella and chemotaxis, adhesins fit host cell receptors examples Streptococcus pyogenes, Neisseria gonorrhoeae, Treponema pallidum, Borrelia burgdorferi, Helicobacter pylori, activate the host cell's cytoskeletal machinery enabling bacterial entry into the cell by phagocytosis examples Shigella,Salmonella, enteroinvasive Escherichia coli, iron mechanism produce siderophores that trap iron, activate the host cell's cytoskeletal machinery enabling bacterial entry into the cell by phagocytosis advantage provides a ready supply of nutrients, protects bacteria from complement proteins, antibodies, etc., biofilm-producing capsule ???? bacterial populations adhering to host cells and embedded in a common capsular mass, bacterial populations adhering to host cells and embedded in a common capsular mass examples Streptococcus mutans, Pseudomonas aeruginosa, Staphylococcus aureus, swim through mucus towards mucosal surfaces ???? certain spirochetes
