Forehead Cultures
1. Examine the 2 forehead culture plates from your bench. Do you observe different colony types?
2. Select a single colony (if possible, a well-isolated colony) for subculturing from one of the two plates inoculated at your bench. What are the characteristics of this specific colony (colors, elevation, margins, etc.)?
3. Using the bacteria from your chosen colony, streak for single colonies on a second TSA plate. (If you need to review this procedure, see Lab 2.)
4. Incubate the plate until next week (Lab 12). Why do you think it is important to streak this colony out for a second time before proceeding with the identification?
