Describe how you will demonstrate the Koch's postulate in linking Buruli Ulcer to its causative organism
Step by step
Solved in 2 steps
- What might be a reason why a Buruli ulcer is initially painless? Why was it necessary to administer antibacterial drugs for two months rather than two weeks? What environmental similarities exist in the endemic countries?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?Describe the evidence linking Helicobacter pylori togastric ulcers. How can these ulcers be cured?
- Describe two characteristics of Streptococcus mutans that contribute to its ability to cause dental caries.Provide an explanation as to why disinfectants, calcium alginate, and cotton swabs should not be used when collecting Neisseria gonorrhea specimens.Why is it not possible to use Koch’s postulates to show that Treponema pallidum causes syphilis?
- 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?Does Enterococcus faecium likely infect the diseased organ through the urinary tract or through the bloodstream? Explain your reasoning.Compare the particular type of host cell that is critical for the initial establishment of an infection between Vibrio cholerae and Helicobacter pylori.
- What are the treatment approach of H.pylori infection after failed the initial therapy? Please briefly explain at your own words.Which streptococci are implicated in the development of dental caries? What is the mechanism of their formation?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)
