Jack, a new MLT at Cape Fear Hospital was given the following information from a patient's urine sample which had been tested for the presence of S. aureus. The urine contained 6.4 x 107 CFU/ml S. aureus, the plate dilution was 10, and the sample had been taken from the 10-5 dilution tube. Calculate the number of bacterial colonies which must have been counted on the plate and what volume of the sample in µl that was actually plated to give the above results. PS, both of these values can be calculated.

You are testing unpasteurized milk for the presence of bacterial contamination. Starting from the undiluted milk, you do serial dilutions, and plate 0.5 ml of 4th dilution on agar.

Ms. Tan came to the laboratory for blood tests because her physician suspected renal disease. The tests ordered were serum BUN, creatine, and electrolytes. The blood specimen was obtained and processed. When the laboratory technician received the serum to perform the tests, he noticed that the seruum had a reddish tinge. Was there a problem with the serum sample? If so, what? What conditions could cause this to happen to a serum specimen?
