This Concept Map, created with IHMC CmapTools, has information related to: Answers_glycocalyx, An outer viscous covering of fibers extending from the bacterium. slime layer Appears as an unorganized, more loosely attached accumulation of gelatinous material., An outer viscous covering of fibers extending from the bacterium. capsule Appears as an extensive, tightly bound accumulation of gelatinous material adhering to the cell wall., Polysaccharides in bacterial capsules function as antigens and initiate adaptive immunity. humoral immunity The production of antibody molecules in response to an antigen., Layers of bacterial populations adhering to host cells and embedded in a common capsular mass. benefits to bacteria in the body Many chronic and difficult-to-treat infections are caused by bacteria in biofilms., Enables certain bacteria to resist phagocytic engulfment by white blood cells in the body or protozoans in soil and water. in the body May resist unenhanced attachment by phagocytes., Appears as an extensive, tightly bound accumulation of gelatinous material adhering to the cell wall. functions Enables some bacteria to adhere to environmental surfaces, colonize, and resist flushing., The production of antibody molecules in response to an antigen. opsonization Antibodies made against bacterial capsules can stick bacteria to phagocytes., Layers of bacterial populations adhering to host cells and embedded in a common capsular mass. benefits to bacteria in the body Bacteria in biofilms are more resistant to attack by antibiotics., glycocalyx (capsules, slime layers, and biofilms) description An outer viscous covering of fibers extending from the bacterium., An outer viscous covering of fibers extending from the bacterium. biofilm Many bacteria secrete a polysaccharide matrix to form a biofilm., Polysaccharides in bacterial capsules function as antigens and initiate adaptive immunity. epitope The actual portions or fragments of an antigen that react with receptors on B-lymphocytes and T-lymphocytes, as well as with free antibody molecules., Polysaccharides in bacterial capsules function as antigens and initiate adaptive immunity. antigen A substance that reacts with antibody molecules and antigen receptors on lymphocytes., Many bacteria secrete a polysaccharide matrix to form a biofilm. biofilm Layers of bacterial populations adhering to host cells and embedded in a common capsular mass., Layers of bacterial populations adhering to host cells and embedded in a common capsular mass. benefits to bacteria in the body Biofilms adhere to environmental surfaces and resist flushing, Layers of bacterial populations adhering to host cells and embedded in a common capsular mass. description Biofilms are functional, interacting, and growing bacterial communities. Biofilms even contain their own water channels for delivering water and nutrients throughout the biofilm community., Layers of bacterial populations adhering to host cells and embedded in a common capsular mass. benefits to bacteria in the body Biofilms enable bacteria to live in close association and communicate with other bacteria in the biofilm through quorum sensing., Appears as an extensive, tightly bound accumulation of gelatinous material adhering to the cell wall. functions Enables certain bacteria to resist phagocytic engulfment by white blood cells in the body or protozoans in soil and water., Layers of bacterial populations adhering to host cells and embedded in a common capsular mass. benefits to bacteria in the body Biofilms enable bacteria to resist phagocytosis and attack by the body's complement pathways., glycocalyx (capsules, slime layers, and biofilms) chemical makeup Usually a viscous polysaccharide or polypeptide slime., Layers of bacterial populations adhering to host cells and embedded in a common capsular mass. benefits to bacteria in the body Biofilms trap nutrients for bacterial growth and enable bacteria to remain in a favorable environment.
