You isolate a new pathogenic bacteria, from the sputum of a human patient, which you hypothesize was the cause of a severe respiratory infection. How could you use Koch’s postulates to prove your hypothesis? Which postulate would not be satisfied if the organism was a human-only pathogen?

You isolate a new drug that seems to kill bacteria. To
understand the mechanism of the bacterial death, you do two
experiments where you grow the bacteria in the presence of either
radiolabeled methionine or radiolabeled uracil and then resolve the
proteins or RNA as appropriate. Although the signal for the
radiolabeled RNA stays constant in both treated and untreated
samples, the amount of radiolabeled proteins is reduced in the
treated sample.

Tick-transmitted organisms (ranging from commensal symbionts to
pathogenic viruses, parasites, and bacteria) are often understudied
and poorly understood. What are some of the inherent difficulties
in researching tick-transmitted diseases? Detail at least five as
well as explain why they are difficult. Then explain why this field
of research can been even more challenging when you are working
with a wildlife population. Again, expecting a 400-500 word
response addressing all the points and questions above. The CDC and
the journal EID...

Q) You want to express human uracil in bacteria in glycosylase
in bacteria. Besides the coding DNA for the glycosylase gene, what

bacteria because of which of the following?
Group of answer choices
presence of an outer membrane in one group and absence in the
other
presence of teichoic acid in one group and absence in the
other
presence of ether-linked lipids in one group and absence in the
other
presence of peptidoglycan in one group and absence in the
other
difference in thickness of peptidoglycan layer between the two
groups

You isolated a new species of bacteria from your backyard and
want to gain insight into its fundamental vs. realized
niche. What would you do? You have access to any and all
resource/technology/method.

Scenario: you isolate a new drug that seems to be particularly
effective at inhibiting a metabolic pathway in tumor cells. You
want to do an experiment that compares global changes in the number
and types of different proteins in cells that are treated with the
compound vs. untreated cells. how can this be accomplished
experimentally.
