If the pathogen were sensitive to an antibiotic, what would be observed when using the disc diffusion method of sensitivity testing?

Question

Quizplus · Accepted Answer

If the pathogen is sensitive to an antibiotic, a clear zone without bacterial growth would be observed around the disc in the disc diffusion method of sensitivity testing. This is because the antibiotic diffuses into the agar medium and inhibits the growth of bacteria in the surrounding area, resulting in a visible zone of inhibition. Choices A and B are unlikely to occur, as overgrowth of the disc or a change in color of the disc would not be related to antibiotic sensitivity. Choice C may occur, but it would indicate resistance rather than sensitivity to the antibiotic.
