- A suspected pathogen is observed from the blood of a diseased mouse. An investigation of the other mice in the area indicates that it is not present in healthy mice. With Koch's postulates in mind, what is the next step to determine whether or not this suspected pathogen is the cause of disease in the mouse? a) Grow the suspected pathogen in a pure culture Ob) Re-isolate the suspected pathogen and show that it is the same as the original pathogen c) Inoculate a healthy mouse with the suspected pathogen O d) Determine whether the organism in the pure culture is the same one as in the original samplearrow_forwardQ3) More than a century ago, Robert Koch realized that to prove the germ theory of disease, he would have to develop a standard for determining causation that would stand the test of scientific scrutiny. (a) Discuss how the principles of Robert Koch's postulate play an important role in modern epidemiology. (b) Explain how an asymptomatic patient can infect another person to the point of causing the person to experience acute symptoms and possibly death.arrow_forwardLyme disease or zika virus https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5729143/ https://www.hopkinsmedicine.org/zika-virus/what-is-zika-virus.html Which virus are you more concerned about?

- Choose one infectious disease from the list below and use the chain of infection to analyze how it is spread. A. Please provide a comprehensive description of cholera. B. Describe the chain of infection cholera. The chain of infection for the chosen infectious disease must clearly include the following: 1. Identification of a) the pathogen, b) the reservoir c) means of transmission d) the susceptible host 2. Describe how one could break the chain of cholera, such as breaking the pathogen link, by providing a specific intervention. 3. Include references and relevant data.arrow_forwardWhat is progeria?
