Figure

Formalin-fixed brainstem specimen from red ruffed lemur (Varecia rubra) infected with Angiostrongylus cantonensis nematodes at a zoo in Louisiana, USA. Hematoxylin and eosin stain shows adult nematodes measuring ≈50–70 μm in diameter with 3–4 μm thick, smooth, eosinophilic cuticle and prominent lateral cords. Nematodes have a coelomyarain musculature and a pseudocoelom that contains a reproductive tract and an intestinal tract, lined by multinucleated cells. Original magnification ×10.
