Unformatted text preview: Lab 7 Page 1 Lab 7 Lab Clean-Up (Page 2) There are a lot of different Lab Exercises Today so theres a lot of different Stuff that needs to be put into different Containers on the Waste Cart. Like an efficient Cook you should be continuously cleaning-up as you proceed. Lab Exercises 1- Viable Count (Pages 3-5) A Viable Count, as the Name implies, tells you approximately how many living (viable) Cells you have in a given Volume. The Viable Count Exercise is fundamentally similar to the Bacteriophage Titer Exercise. 2- Water Quality Testing (Pages 6 and 7) The Most Probable Count, as the Name implies, is a statistical Determination of the Number of Coliform Bacteria per 100 ml of a Fluid (usually Water). 3- Phage Titer Results (Page 8) The Phage Titer Exercise allows you to determine the Number of Phage in the initial Phage Suspension we gave you two Labs back. 4- Antibiotic Results (Page 9) The Antibiotic Testing Exercise allows you to determine Sensitivity or Resistance of E. coli and Staphylococcus epidermidis to several Antibiotics. 5- Isolations (Pages 10-13) Isolations will once again involve making Gram Stains, measuring the stained Bacteria, and then streaking a new Plate from the same Colony you used to make the Gram Stain. 6- Hemocytometer (Page 14) Hemocytometers, as the Name implies, are Devices that can be used to determine the Number of Cell-Size Entities in a given Volume of Fluid.
