Why are encapsolated bacteria generally more pathogenic than un-capsolated strains.
a. Because capsule allows the organism to hide in the body of the host.
b. because the capsule causes the phagocyte to mutate c. because the capsule protects bacteria from host immune cells
d. because the capsule kills the phagocytes
e. because the capsule stimulates a potent immune response in the host.

- In certain bacterial illnesses, particularly lung infections with Pseudomonas aeruginosa, a physician may not treat the patient with antibiotics (which will kill the microorganisms), rather give the patient anti-inflammatory medications. 1. Why might a physician choose to inhibit inflammation in the case of an infection? 2. What types of damage might the inflammatory response do to the surrounding tissues, not just the bacteria it was designed to combat? 3. We talked a lot about controlling the complement cascade because of its potentially damaging effects, what are some of the ways the body can control inflammation and the inflammatory response?arrow_forwardWhich of the following substances is not produced by phagocytes todestroy engulfed microorganisms?a. hydroxyl radical b. superoxide anion c. hydrogen peroxide d. bradykininarrow_forwardYour patient who is recovering from a first time wound infection caused by Staphylococcus aureus.
