PPNG b. MRSA 2) How does the MIC test differ from the Kirby-Bauer test? 3) Were all of the conditions of a standardized Kirby-Bauer test met as you performed this assay? If not, which were not? 4) What is the significance of colonies that develop within otherwise clear zones of inhibition? If the laboratory report for one of your patients indicated colonies within the zone, what concerns would you have for your patient?Give five (5) other examples of samples that are best prepared using Smear Preparation Technique (example: Human RBCs). Explain why.

- 1) Dosage calculation with same units of measure. EX: MD orders 1000mg Ancef. You have available 2000mg in 10mls. How many mls you give?Match the chemical reaction to the visual effect of the product/biochemical test description 1. This assay's color change relies on an initial reduction reaction resulting in a black precipitate if the organisms is "positive" 2. The visual production of gas from this reaction indicates this organism can break down toxic byproducts of aerobic respiration. 3. This assay relies on a pH indicator (phenol red) for a color change. An organism that was "positive" for the certain enzyme in this assay, would result in a pink color change. 4. If an organism was incubated in simple broth containing a phenol red pH indicator and a sugar source, and the broth turned yellow following bacterial growth, that would be evidence of this reaction occurring. 5. The reaction representing this assay, works by producing a red colored product upon addition of a reagent, which tells us the organism possesses the enzyme required to break down a particular amino acid.Bradford Assay Fill in the average A595 and A595 of sample minus A595 of blank.

This preparation should be carried out in a good hood to avoid exposure to ammonia. The operator should wear rubber gloves and protective goggles because 2-haloallylamines and ethylenimines can cause severe skin and eye irritation.A 2-l. three-necked flask is fitted with a sealed mechanical stirrer, a gas-inlet tube, and a dry ice condenser protected from the air by a soda-lime drying tube (Note 1). The system is flushed thoroughly with dry ammonia, and 32.8 g. (0.84 mole) of sodium amide (Note 2) is added to the flask. The system is again flushed with ammonia, the condenser is provided with dry ice covered by acetone, and 1.2 l. of liquid ammonia is condensed in the flask.
