Answer:
Etest
Explanation:
The Etest is used for sensitivity testing particularly for anaerobic microbes. In the test, the agar medium in a single plate is streaked in three different directions with the microbe under study.
The plastic Etest strips are arranged on the surface of the medium in such a way that they appear radiating out from the center of the plate. Each of the plastic Etest strip serves as source for different antibiotics. The plate is incubated to allow the elliptic zone of inhibition to appear which in turn are used to determine the MICs.
