Suppose during a laboratory period you were provided with sterile Petri dishes to expose to the environment in the following ways (inoculation):
- 1. Several coins pressed temporarily on the media
- 2. Hair combed over exposed petri-dishes
- 3. Expose the petri-dish by coughing onto it
- 4. Swabbing your skin and inoculating the petri-dish with swab
Discuss what you would expect to observe on the Petri dishes (#1-4) after 48hrs of incubation ? which habitat sampled would you expect to contain more bacteria and why?
