Step by step
Solved in 2 steps
- Understand the pathogenesis of cholera.Compare the mechanism of virulence for Vibrio cholerae and enterotoxigenic E.coli. Specifically, how do these bacteria bind to host cells and what factors are involved in producing the diarrhea observed in infected patients?Compare the severity of symptoms between the Cholera causing Vibrios and the non-cholera Vibrios. List treatment options for cholera.
- Describe the major features of how cholera toxin damages intestinal cells.How can we prove the pathological and clinical effects of cholera are caused by the production of enterotoxin?How can we prove the pathologic or clinical effects of V. cholerae are due only to the production of the enterotoxin by the pathogen? (hint: exclude endotoxin LPS)
- Explain how Vibrio cholerae causes cholera.Identify two virulence factors in the picture and explain, in detail, how they mediate V. cholerae pathogenesis.The general public takes for granted the link between an infectious agent and a given infection Discuss the requirements established by Koch, the nineteenth-century German scientist, before ascertaining, for instance, that Helicobacter pylori bacterium is the cause of the gastric ulcer. Why is it so essential to meet these conditions?
- Explain how the body (including cells, organs, organ systems) is affected by the bacterium called Neisseria meningitidis? Are there any long-term effects caused by the bacterium, even after recovery?Describe the two most important public health measures that can be put in place to prevent a cholera outbreak.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?
