An agar plate was flooded with a culture of a species of bacterium usually found in the mouth. Four steriled paper discs, A, B, C, and D, each containing a different brand of mouthwash, were then placed on the agar plate. The drawing shows the appearance of the plate after it had been incubated below body temperature for three days, this is to ensure that the bacteria are not harmful to humans.

Describe the aseptic technique that would be used when flooding the agar plate with bacteria

prosider:- prick the tip of finger with steriled needle. make a drop of blood in a clean slide and add a drop of water to in.so heamolysis can occure.Then add a drop of saline and heat the slide to evoparate the solution.later add a drop of glasial acitic acid and cover it with coverslip.Heat gentely over the spirit lamp till the bubbles occures.Add another drop of glacial acitic acid to the slide of coverslip.Allow it cool and observe under the microscope.

Result:- Dark brown red crystels (haemin crystels) are seen under microscope.
