Question

Quizplus · Accepted Answer

The bright fuchsia stain shown in the figure is indicative of the acid-fast staining technique, which is used to detect the presence of cell walls with high lipid content, such as those found in Mycobacterium spp. and some other bacterial species. The possible presence of Bacillus anthracis is not relevant in this context. Therefore, choices A, D, and E are incorrect. The Gram stain is a different type of staining procedure that uses crystal violet and safranin to differentiate between Gram-positive and Gram-negative bacteria based on their cell wall properties. Although some Mycobacterium spp. may show some degree of Gram stain reactivity, this is not a typical characteristic of this genus, so choice B is also incorrect.
