Fig. 2

Lung of alpaca no. 2 showing granulomatous lesions with necrotic centres (triangles) surrounded by macrophages and lymphoid cells infiltrating the lung parenchyma. Haematoxylin and eosin staining. Bar = 50μm

Fig. 3

Lung of alpaca no. 2 showing granulomatous lesions compounded by cellular debris (black triangle) surrounded by palisading spindle-shaped macrophages at the edges of the necrotic areas (white arrows) with rare presence of large multinucleated cells (black arrow). An infiltration of lymphocytes, plasma cells and fewer neutrophils scattered between the macrophages is visible on the left side of the photograph. Haematoxylin and eosin staining. Bar = 50μm
