Microbiology Q1 Q2 Escherichia coli is a red-pigmented organism. True O False The results of the MR-VP test can be directly read from the test without the addition of any other chemicals. True False
Microbiology Q1 Q2 Q3 Salmonella is associated with the handling of contaminated beef True False Which test(s) would you use to find out more about Gram-positive organisms? SIM O MR Citrate None of the tests listed. Fermentation of sugars usually results in end products. Acidic Basic (Alkaline)

Microbiology Q1 Q2 Q3 Which medium contains a pH indicator to show pH change caused by fermentation? Glucose Broth Lactose Broth SIM Lactose and Glucose Broths Lactose, Glucose, and SIM What is the Gram reaction of Escherichia coli? Positive Negative Gram Neutral It is an acid-fast organism. How do we test for gas production during glucose fermentation? The medium turns yellow. There is a bubble that collects in the Durham tube. The medium turns red. We cannot test for gas...
Microbiology Q1 Q2 Q3 What is the color of SIM medium that contains an organism that forms hydrogen sulfide (is positive for sulfur)? Blue Black Red Yellow Which test(s) would you use to find out more about Gram-positive organisms? SIM MR Citrate None of the tests listed. Fermentation of sugars usually results in end products. Acidic Basic (Alkaline)
Microbiology Q1 Q2 Q3 One organism that is positive for citrate is You added methyl red to your MR test and observe a red color. The test result can be interpreted as You forgot to label a tube with a slant but you remember that its original color was green and now after incubation, the slant color is blue. What is the name of the test?
Microbiology Q1 Q2 Q3 A Durham tube is commonly added to the lactose or glucose broth to test for the release of Acid gas Both acid and gas SIM stands for sulfur, indole, and methyl red. True False The citrate slant is a differential medium. True False
Microbiology Q1 Q2 Q3 Which reagent(s) are used to perform the EMB test? What is the color of a negative Methyl Red test? Pseudomonas is an opportunistic pathogen that commonly causes urinary tract infections. True False

Microbiology Q1 Q2 Q3 A phenol red glucose broth with a Durham tube has been inoculated and incubated. After 48 hours, the broth is turbid and bright yellow and approximately half of the contents of the Durham tube contains bubbles. Interpret these results. The organism will ferment lactose as well. The organism is fermenting glucose. The organism is an obligate anaerobe. The organism is fermenting lactose and producing ethanol and CO2. What can be detected using SIM medium? Check all...
