What conclusions can you draw from culture growing on the starch plate in the half labeled A in the image below? (Choose all that apply)

Based on the phylogenetic tree the athlete was most likely infected during her swim in the Seine River.

What kind of locked system stores medications and requires a badge swipe and a scan finger print before allowing the drawer to open? 

What conclusions can you draw from the culture growing in the gelatin tube labeled A in the image below? (Choose all that apply)

Scenario for questions 6 through 7: To study the electron transport chain you decide to make two mutants strains of Escherichia coli.  Mutant 1 has NADH dehydrogenase completely knocked out (i.e. the protein is not present in the mutant) and Mutant 2 has a succinate dehydrogenase that can no longer pass electrons into the Q cycle.  

What conclusions can you draw from the culture growing on the blood agar plate labeled B in the image below? (Choose all that apply)

Based on the phylogenetic tree the isolated microbe from the athlete is most closely related to which of the following microbes?  (Choose all that apply)

What refers to the strength of a medication?

rDNA is often used to build phylogenetic trees because all organisms have this gene for making the DNA polymerase.

The athlete was originally prescribed penicillin (a  beta-lactam) to treat her infection, but it wasn’t very effective.  As the athlete’s doctor, explain why penicillin may not be effective against her specific infection.  To completely answer the question be sure to address the following: How does beta-lactam function, i.e. what is the target of this drug? Why are beta-lactams typically less effective against microbes with the cell wall type of the isolate than other cell wall types? Describe one specific mechanism of antibiotic resistance that may make the drug less effective.  We discussed many in class, you should only describe one for this question.
