Fig. 2From: Immunohistochemical characterization of tuberculous lesions in sheep naturally infected with Mycobacterium bovisBronchial lymph node; immunohistochemical characterization of cellular populations in developed granuloma. Scattered T (arrow) and B lymphocytes are observed towards the periphery of the granuloma (a and b, bar = 50 μm). The presence of immunolabelled macrophages predominated over the whole granuloma (c, bar = 20 μm), while plasma cells were abundant and peripherally located (d, bar = 20 μm)Back to article page
