You can be given prepared slides or micrographs of anything, so, in that sense, it's wide open. Actual tasks are limited due to the live specimen list noted above, time constraints, and virtually no chemicals.
I believe SOUP had you prepare your own slide of yeast cells with crystal violet, and draw it under 40x (all in 10 minutes).

does anyone know how to differentiate bw treponema and borrelia (syphilis and lyme) under the microscope? also are there any other microbes that look really similar?

Why did most of the national topics in 2011 and 2012 not appear on the test? Other than the two additional species, and the competition graph, there wasn't much. Did the national supervisor every indicate why he chose to do this? Same coordinator this year?

In my notes I have that Borellia is 20 microns long and treponema is 12 microns long, but that doesn't help you if they only give you a picture of one without a scale.

Also, between Viridans Strep. (usually alpha or gamma hemolytic) and Group A Strep. (beta hemolytic), I assume they will give you an image of blood agar and ask you to determine what type of hemolysis is depicted.

Are you referring to the national tests from 2011/2012? I have the one from 2011, and it seems to cover quite a broader range of topics (including antibiotic resistance) than most tests, although not particularly in depth. I think the MIT test was a pretty accurate representation of what this year's nationals test might look like. The nats supervisor in 2011/2012 was Karen Lancour, so I assume she will be writing the test again this year.
I also took the Wright State invitational microbes test, and it was well-written, but I'm not certain who wrote the test.

lol yea i found some of the ""stations"" from the wright state test as "practice quizzes" for weird websites trying to teach supplemental microbiology. The MIT one almost seems like a copy paste + or - a few things of the national tests. Similar sections, same graphs, ...... but I agree its good prep :)
