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
Question 1 (1 point) An unknown organism was inoculated into a phenol red tub and produce a yellow coloration. The same organism was inoculated into a purple broth tube resulted in growth after the incubation period. Green slant tubes were also inoculated and resulted in a blue coloration. However, this organism was negative for motility within a SIM tube. Which of the following is the unknown species? Salmonella typhimurium Shigella sonnei Enterobacter aerogenes Klebsiella pneumoniae Escherchia coli O Proteus mirabilis...

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...
You have obtained samples from a patient who is in the ICU at your hospital. You perform the Gram-Stain and IMVIC tests, and see the following results: Gram-Stain Upon examination under the microscope you view pink colored rods. IMVIC Indole: After the addition of Kovac's Reagent, you see no color change at the top of the media. Methyl Red: After the addition of methyl red, your broth immediately turns a red color. Voges Proskauer: After the addition of VP reagents...
