- Why does Helicobacter pylori cause ulceractions in the lining of the Stomach? 1)The microbes secrete a toxin that prevents the host from detecting invasion of the microbe and thus allows it to thrive in the stomach and damage the host cells. 2)After invasion of the microbe in the cells lining the stomach, they are no longer able to produce mucous to protect the host cells from acid erosion 3)The microbe produces an enzyme that causes the cell to produce potent digestive enzymes that erode the stomach lining. 4)Once the microbe has entered the stomach, it releases digestive enzymes that degrade the mucous secreting cells.Which of the following statements about Pasteurella multocida is false?a) Infections generally respond to a penicillin.b) It can cause epidemics of fatal disease in domestic animals.c) It is commonly found in the mouths of biting animals, including humans.d) A vaccine is used to prevent P. multocida disease in people.e) Cat bites are more likely to result in P. multocida infections than dog bites.Match the organism in column A to the symptom/manifestation in column B that fits it most appropriately.
