Textbook Question
Chapter 3, Problem 1CA
The effectiveness of sanitation procedures in hospitals is determined by sampling surfaces for bacteria. Samples can be taken by rubbing a sterile, moistened cotton swab on a surface and inoculating a nutrient agar plate or with a Rodac environmental sampling plate. The 67-mm Rodac plates are designed so that an agar medium can be overfilled, producing a dome-shaped surface that can be pressed onto a surface for sampling microbes. As the sanitation control officer, you test each method to determine which you will use. What can you conclude from these results?
