In certain bacterial illnesses, particularly lunginfections with Pseudomonas aeruginosa, aphysician may not treat the patient with antibiotics(which will kill the microorganisms), rather give thepatient anti-inflammatory medications.1. Why might a physician choose to inhibit inflammation inthe case of an infection?2. What types of damage might the inflammatory responsedo to the surrounding tissues, not just the bacteria it wasdesigned to combat?3. We talked a lot about controlling the complement cascadebecause of its potentially damaging effects, what aresome of the ways the body can control inflammation andthe inflammatory response?

Introduction :- Pseudomonas is a type of bacteria that is found commonly in the environment, like in…

High numbers of “good” bacteria are foundin the intestine and on the skin. The immune system needs to protect these areasfrom invading microbes, but cannot respond as strongly to the normal microflorawithout causing problems. What are somepossible ways that immune cells coulddistinguish “good” from “bad” bacteria?
In the disease mononucleosis (“mono”), the spleen enlargesbecause of increased numbers of phagocytes and other cells.Common signs and symptoms of this disease include palecomplexion, a tired feeling, and a lack of energy sometimesto the point of not being able to get out of bed. What mightcause each of these signs and symptoms?
Which of the following substances is not produced by phagocytes todestroy engulfed microorganisms?a. hydroxyl radical b. superoxide anion c. hydrogen peroxide d. bradykinin
What mechanism do Tc cells use to identify anddestroy infected cells in the body? How do Th cells differfrom Tc cells, and how do the different subsets of Thcells differ from each other?
Macrophages perform the final job of removingtissue debris and other products of infection.Indicate some of the possible effects when thesescavengers cannot successfully complete thework of phagocytosis.
It would be disastrous if a complement attack werenot confined to the surface of the pathogen that is the tar-get of the attack. Yet, the proteolytic cascade involved inthe attack liberates biologically active molecules at severalsteps: one that diffuses away and one that remains boundto the target surface. How does the complement reactionremain localized when active products leave the surface?
Pathogenic infections induce damage to the host by a variety of mechanisms. While many mechanisms are direct effects of the pathogen, some damaging mechanisms result from the immune response to the infection. Examples of damage caused by the host immune response are: a) Exotoxin production, endotoxin b) Cell-mediated inmunity, direct cytopathic effect c) Endotoxin, inmmunune complexes d) Direct cythopathic effect, endotoxin e) Cell-mediated inmunity, inmmunune complexes
What is the difference between a true pathogen and an opportunisticpathogen?a. True pathogens cause a disease in the presence of immunosuppressionwhereas opportunistic pathogens do not.b. Opportunistic pathogens develop virulence properties whereas truepathogens do not. c. The diseases associated with true pathogens may vary in presentationranging from mild to severe infections whereas opportunistic pathogensalways present in severe form.d. True pathogens cause disease in healthy individuals whereasopportunistic pathogens typically cause disease in clients who areimmunocompromised.
Shigella, Mycobacterium, and numerous other pathogens have developedmechanisms that prevent them from being killed by phagocytes.a. Suggest two or three factors that help them avoid destruction bythe powerful antiseptics in macrophages.b. Suggest the potential implications that these infected macrophagescan have on the development of disease.
