Donovan bodies are diagnostic findings for granuloma inguinale; which description is correct?

Explanation:
Donovan bodies are intracellular inclusions found inside macrophages (mononuclear cells) within the lesions of granuloma inguinale. They are characteristic diagnostic features because these intracytoplasmic bodies, revealed on special stains (like Giemsa or Wright), reflect the presence of Klebsiella granulomatis. This is why the correct description is Donovan bodies in mononuclear cells. They are not simply Gram-positive cocci, nor are they flagella or a capsule stain pattern. The key idea is that these bodies reside inside mononuclear cells in tissue, not as free bacteria or as external staining patterns.
