urinalysis identifies a negative result for reducing sugars, yet the test for glucose (glucose oxidase reaction)  was positive on the dipstick.  What do these results suggest? The patient is on mega doses of ascorbic acid, This may suggest that the patient has galactosemia, The urine collection container was cleaned with bleach, There is an analytical error in the testing?

In a tabulated form, list down the advantages and disadvantages of "each" preservatives used in a urine sample.

in the document you submit, please describe the results for this test… (like yellow equals what?) Methyl Red and Voges-Proskauer (MRVP) Test: 1) Give me the expected results for Enterobacter aerogenes and Escherichia coli (for each bacteria, give me the MR result and VP result)

procedure/s in performing aseptic transfer of bacterial cultures in (include illustration) (1) broth culture to broth

How can you test the chemical composition of calcium carbonate crystals precipitated by ureolytic bacteria? What are the types of crystals formed? How can you fest those types?

Describe the evidence of Picric acid test to show a positive result for the presence of a specific sugar in a material or substance.

Answer the given question below. Provide the full solution. See attached photo for the given values to be computed. A chicken salad was picked from a local subway and brought to the laboratory. 200 grams were addedto 200 ml of sterile buffered peptone water and homogenized for 2 min. The solution was chilled toprevent overheating. The final dilutions and the collected data are presented below. The plate mediumis TSA agar. Answer parts (a), (b), and (c). (a) There are ______________ CFU per ml of homogenate.                                                  (b) There are_______________ CFU per gram of the chicken salad.                                         (c) What does CFU stand for? ______________________

the image contains results of the fluid thioglycolate medium tests. Please explain the results and the chemistry of each tube? Thank you

A sample of Earth Alive Soil Activator was diluted by transferring 1 gram into a 9 ml dilution blank (tube A) and then serially diluted five (5) more times by transferring 1 ml of a previous dilution into a tube of 9 ml of sterile water. After making these serial dilutions, 2 ml samples were taken from tubes D, E, and F, added into empty petri dishes, and molten PCA was poured into each petri dish. Tubes A, B, and C were heated in a 80˚C water bath for 30 minutes, 2 ml samples of these tubes were added into empty petri dishes, and molten PCA was poured into each petri dish. These plates were allowed to solidify, and they were incubated at 35˚C for 48 hours. After the incubation period, you counted CFUs on all 6 plates. The results of your CFU counts are contained in table 1. Table 1. CFU counts for 3 plates from the heated dilutions (A-C) and the 3 plates from the non-heated dilutions (D-F) # CFUs   Not heated Heated A -- 400 B -- 45 C -- 6 D 350 -- E 31 -- F 2 --…
