Question

an experiment was carried out for bacterias from the nose
the other sample was from the cellphone
the other was unknown
what is the results of this experiment and why?

Answer 1

This experiment involves the study of the bacteria present in the nose, cell phone and the unknown that we have to guess its bacteria type with the previous two sites.

So, the bacteria that were present in the nose will form the microflora of the internal environment whereas, the bacteria present on the cell phone will form the microflora of the external environment. The bacteria that are present in the unknown site are compared with both the microflora of the nose and the cellphone and it is observed if the microflora of the unknown site is more like the external (cell phone) or the internal environment (nose).

If the microflora of the unknown site is more like the external environment (cell phone), then it indicates that the site of bacterial isolation is from the environment. If the microflora of the unknown site is more like the internal environment (nose), then it indicates that the site of bacterial isolation is from inside the body itself.

Hope it helps, Good luck !!!!!
