Textbook Question
Chapter 4, Problem 5CTQ
a. Describe the characteristics of an endospore-producing bacterium that make it an ideal candidate for bioterrorism but an undesirable intruder in a hospital setting.
b. Explain why the production of endospores is not considered a method of reproduction in most bacterial species.

b.explanation on how the bacteria should be able to reisolated from the experimentally infected host organism and should show similar properties of the original bacteria
To describe: The reasons for which passive transport is required for the bacteria.
a. What oxygen requirements do your think this bacterium will have (obligate aerobe, obligate anaerobe, facultative anaerobe, aerotolerant anaerobe, or microaerophile), and why?
b. You run a thioglycollate test of your isolated bacterium. Based on your response to Part A, which thioglycollate tube best represents the result you would expect for your bacterium? Explain your response. If the result you would expect is not represented, explain what the tube should look like.
c. What would you expect to be the result of a catalase test of your bacterium?
d. What techniques or specialized equipment, if any, would you need to grow cultures of this bacterium?
