a.
To explain:
The reason as to why growth on the plate was observed after incubation of a sample aseptically obtained from growth free portion of the zone of inhibition at
Concept introduction:
Kirby-Bauer test is also called “disc diffusion antibiotic sensitivity test”. It is a test to determine the antibiotic sensitivity of bacteria. In this test, antibiotic discs are placed in Petri plates containing bacterial culture. A particular zone of inhibition around the disc represents the bacterium in the culture is susceptible to that antibiotic.
b.
To determine:
Whether amoxicillin (the tested drug) is an effective drug choice for the treatment of infection caused by the cultured bacterium.
