TARGETS
| 23. Microorganisms, cellular and viral, can interact with both human and nonhuman hosts in beneficial, neutral or detrimental ways. | State two ways that the normal microbiota (or probiotics) are beneficial to a human host. Name two sites on the human body colonized by the normal microbiota, and give an example of the type of organisms found at those sites. Describe at least two innate physical defenses in the human body that are used to fend off an infection. Given a particular pathogen (symbiont), describe how it creates cell damage (benefits) in its host. |
Compare and contrast commensal, symbiotic, and pathogenic relationships. Explain what adaptations are necessary for a bacterium to survive in the respiratory tract, skin, intestinal tract, or urinary tract. Describe how the human microbiome influences the host human organism. Describe a situation that could lead to the normal microbiota causing disease. Given a human defense, describe a mechanism that would allow a bacterial pathogen to evade it. |
