Fig. 3. Morphology of the tissue cyst recorded in plains vizcachas. Mammary gland photomicrograph illustrating a tissue cyst with a thick wall made up of a collagen fibers outer layer and the inner layer consisting of nucleated host cells enclosing thousands of spindle-shaped bradyzoites (Bz). Inset: the bradyzoites showed a conoidal (anterior) and a nonconoidal (posterior) end where the nucleus is located, and they exhibit cluster arrangements where they are ordered parallel to each other. Masson's trichrome staining.
