Allergies have been bothering you lately. As you were inoculating your streak plate with E. coli you sneeze. With a plate in one
hand and an inoculating loop in the other you were unable to quickly cover your mouth. You tried to sneeze into your arm but your unstifled sneeze was greater than your arm could shield. Following incubation of your plate, what do you expect to see on the plate next lab?
There will be E. coli along with bacteria from your mouth on the plate.
Microorganisms are in the air transiently so there could be growth from contaminants in the air.
Explanation:
There are many microorganisms around us and in our body, some microorganisms are present in the air, being carried everywhere by the wind. Our mouth is also charged with microorganism, so we can conclude that if you want to sneeze the moment you are inoculating an E. coli, it is ideal that you cover the terror so as not to contaminate the inoculation, but if you cannot cover the spiro, the inoculum plate will be contaminated with microorganisms with microorganisms from its mouth, which will grow along with E. coli. Another thing that will happen is that some airborne microorganisms will be carried to the dish that will result in the growth of contaminants in the air.
