Fig. 3From: Immunohistochemical characterization of tuberculous lesions in sheep naturally infected with Mycobacterium bovisBronchial lymph node; immunohistochemical characterization of cellular populations in terminal granuloma. No T lymphocytes were observed within the granuloma (a, bar = 20 μm). The main cellular type were B lymphocytes forming clusters surrounding the necrotic area of the granuloma (b, bar = 200 μm; inset: bar = 20 μm). Positive immunolabelled macrophages and plasma cells were randomly and sparsely distributed (c and d, bar = 20 μm)Back to article page
