Figures & Tables

Fig. 1

Macroscopic lesions in dogs with leishmaniasis in a central region of Colombia. A, B – skin lesions (exfoliative and ulcerative dermatitis) on the head, neck, and ears (Fig. B lower panel is a magnification of the delineated square in A). C, D – splenomegaly with nodules protruding on the irregular surface of the organ (Fig. D is a magnification of the delineated square in fig. C). E, F upper panel – ulcerated nodule in the lung (Fig. F upper panel is a magnification of the delineated square in Fig. E). F lower panel – a non-ulcerated nodule protruding from the surface of the lung of a different dog

Microscopic lesions in dogs with leishmaniasis in a central region of Colombia. A, B – auricular dermatitis associated with intracellular amastigotes present within macrophages (arrows). C, D – lymphadenitis showing abundant promastigotes parasites (arrows) within phagocytic mononuclear cells. E – spleen with severe depletion of lymphocytes (white pulp) and apparent hyperplasia of red pulp. F – lung with moderate to severe interstitial pneumonia. G – kidney showing interstitial nephritis with tubular degeneration. H – small intestine showing lymphoplasmacytic infiltrate

PCR Amplification of a 314 bp DNA fragment of a Leishmania RNA gene. Upper panel – M:100 bp ladder. Lane 1 – negative control (without template DNA). Lane 2 – positive control of L. amazonensis. Lane 3 – spleen. Lane 4 – skin. Lanes 5, 6 – lymph nodes. Lane 7 – positive control of L. infantum. Lane 8 – positive control of L. braziliensis. Lower panel – M: 100 bp ladder. Lane 1 – positive control of L. amazonensis. Lanes 2–5 – spleen samples from three serological positive dogs
