Step by step
Solved in 2 steps
- What part of the tube changes color first (in Resazurin Reduction Test between Pasteurized and Raw Milk)?In the Methyl Red-Voges Proskauer test, the samples were not transferred into sterile tubes for developing the MR or VP test. Why weren't sterile tubes required?In the Harada-Mori culture technique, how are you going to dispose the culture tubes? Is it suitable to use refrigerated samples for this procedure Why or Why not?
- Why is the looping out method preferable for sputum specimen for acid fast smears?You saw no color change in both the first step and second step of the Nitrate Reduction test. What is the result of this experiment? Also, explain what happens when an excessive amount of zinc is added in the second step of this test.which kind of sample gives positive result for Molish test?
