Module 29Distinguish loose association, adhesion, and colonization as types of interactions of bacteria with epithelial cellsMake a diagram of epithelial cells, the types of interactions with bacteria, and describe mucous membranes Describe what nutrients are provided on certain skin areas and what environmental stresses microbe have in some skin areas - Nutrients are provided to certain ski areas gland secretions contain water, amino acids, salts, and fatty acids- Environmental stress microbes has in some skin areas are ages of person, personal hygiene, moisture.Explain what anti-microbial enzymes are in saliva and how their activities protect against some bacteria - Anti microbial enzymes that are in saliva are lactoperoxidase and lysozyme, inhibit bacteria- Lactoperoxidase- makes a reactive oxygen species as a product that kills bacteria- Lysozyme- enzyme that cleaves peptidoglycanCompare dental caries and gingivitis and the role microbes play in development of these diseases- Dental caries- cavities, acids from microbial metabolism cause biofilm- Gingivitis- is an infection of the gingival crevice, infection leads to tissue inflammation and underlying bone lossOrder the steps in the formation of tartar, starting with a dental cleaning - Glycoproteins on surface- cells attach- Attachment and colonization- growth=biofilm- Plaque- thick biofilm= plaque - Tartar- plaque= ca+= tarterBe able to state how the stomach acts as a barrier to pathogen entryThe stomach provides a major barrier to entry of pathogens into the gastrointestinal track because it has a pH of about 2 which kills most microbes Describe in a general way how microbial populations and diversity change as food moves through the intestinal tract - Tract goes from acidic to neutral- SI changes to less acidic, more anoxic, and higher microbial abundance and diversityDescribe where Helicobacter is found and what disease it causes- The helicobacter is found in the stomach - disease it causes is ulcersBe able to label the locations of the upper and lower respiratory tract diagram and where microbes can be found- Upper respiratory- sinuses, nasopharynx, pharynx, oral cavity, larynx- Lower respiratory- trachea, bronchi,
