Step by step
Solved in 2 steps
- Briefly discuss how urease assists Helicobacter pylori in evading the body's protective nature.Explain the role of pylori in the pathogenesis of peptic ulcers. Which populations are most susceptible to peptic ulcers? Is H. pylori normal flora? If so, what causes the species to become pathogenic? Construct at table to compare and contrast the 5 steps of microbial pathogenesis. How does extracellular growth differ from intracellular growth? Diagram the 5 step pathogenesis cycle for coli O157:H7, an extracellular, intestinal pathogen acquired by consuming contaminated food/water. Be sure to include the role of exoenzymes and the Shiga exotoxin in your diagram. (2 points) Explain the pathogenesis of Listeria monocytogenes. Be sure to include temperature regulation, intracellular growth, and at risk groups in your discussion.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.
- Resistance to antimicrobial agents is more commonly seen in hospital-acquired infections with enteric bacteria than in community-based infections with the same species. Explain why this is so.Give two sources of Pseudomonas aeruginosa.Contrast Streptococcal toxic shock syndrome from Staphylococcal toxic shock syndrome.
