Step by step
Solved in 2 steps
- Why are Staphylococcus species so numerous onskin?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.If there is a causal relationship between the presence of H. pylori and ulcers, how might you explain that 50% of the patients with a normal endoscopic examination were infected with the bacteria?
