What does the process of taking a culture involve?

Question

What will be an ideal response?

Answer 1

To take a culture, a scientist wipes a sterile swab across the surface of the animal's skin, inside the mouth, or another body area. The swab is rubbed onto a sterile growing medium inside a sterile petri dish, where the bacteria feed on nutrients. Next, the dish is placed in a temperature-controlled chamber to encourage bacterial growth. Within a few days, the bacteria grow and multiply, and the scientist is able to obtain enough bacteria to examine and identify under the microscope.
