his is a typical lab exam question.  (Problem-solving, uses current topic.) Your TA performed the antibiotic disc experiment using supplies from their research lab.  The antibiotic discs had the year 2002 written on their containers. Your TA grew a pure culture of unknown bacteria.  They applied the culture to a fresh agar plate and applied the 2002 antibiotic discs to the plate and incubated it for growth.  They found that the mystery bacteria species was resistant to all three antibiotic discs that were applied to the plate. Are there any control groups that could be used to confirm or refute this multi-drug resistance?  Describe them.

You perform the Methyl-Red(MR)& Voges-Proskauer(VP)test and gather the followingresults: (Uploaded picture). VP test result is on the left, MR test result is on the right. A) Please interpret these results. B) Your fellow researcher and yourself are sure your bacterial sample is either E. coli or P. vulargis. Basedupon the work we have done in lab which methods will help you determine which bacteria it is? Please explain why, the results you would want to observe and provide analysis of those results.

I completed the chart, and I'm supposed to figure out the unknown bacteria, there are 12 unknown culture, out of which of them resemble my chart the most? (My chart is the one in pink with the information filled out)

I need help with a microbiology question on my homework, the question is which medium would you expect brownian movement to cause interpretation difficulties and why? The mediums We used are wet mounts and motility adgars. Along with bacterias being k.pnemoniae(non motile) and p.mirabilis (motile). Also, the site is saying that I took this question from another site, this question is apart of my homework that I do not understand which medium cause interpretation issues with brownian movement. Thank you!

(ACADEMIC) Time The solid matrix that is usually used to attach the target DNA in southern blotting technique is usually a O a. Polyacrylamide gel O b. Petri dish Oc. Cell culture plate O d. Membrane Oe. Micro-titer plate CLEAR MY CHOICE

Create a dichotomous key please

Hello, please read the attached Microbiology question and answer correctly.  *If you correctly answer the question, I will provide a Thumbs Up to you. Thank you.

In this section you will present the results of all the tests that was done to identify your organism Enterobacter aerogenes (your observation). In the laboratory we tabulated our results and created a chart (ID Matrix). Here you are describing the result of each test (in your own words). Include the name of the Indicator used (if any). Color changes that represent positive/negative results must be mentioned here. Your organism is a Gram-negative organism (Enterobacter aerogenes) You must discuss all the IMViC tests and Hydrogen sulfide test in DETAIL. 1. Indole test  2. Methyl red test 3. Vogues-Proskauer test  4. Citrate Test 5. Hydrogen Sulphide Test

Can your draw it out and explain it to me please

You are given a mix culture of S. aureus,E. coli and P. aeruginosa. Besides the streak plate method what other methods could you use to separate the bacteria? Please state what method(s) you would use, the result you would be looking for to help identify each bacterium and the interpretation of the result.
