Pathological findings associated with toxoplasmosis in free-ranging marmosets (Callithrix spp.).
(A) Random lytic necrotizing hepatitis with adjacent mild lipidosis, Liver, HE, Scale bar = 100 μm. (B) Immuno staining for T. gondii zoites, Liver, DAB, Scale bar = 60 μm. (C) Splenitis, histiocytic, with fibrin deposition in red pulp, Spleen, HE, Scale bar = 60 μm. (D) Immuno staining for T. gondii zoites, Spleen, DAB, Scale bar = 60 μm. (E) Interstitial pneumonia, characterized by alveolar walls expanded by histiocytes, lymphocytes and plasma cells, with moderate number of foamy macrophages, mild alveolar hemorrhage, diffuse congestion, and intracytoplasmic Toxoplasma gondii zoites (inset), Lung, HE, Scale bar = 60 μm. (F) Immuno staining for T. gondii zoites, Lung, DAB, Scale bar = 60 μm.
