Histology of infections by Accacoelium contortum in pharynx of the ocean sunfish Mola mola (L.) from the Western Mediterranean. a Uninfected pharynx (b refers to area magnified in (b); scale bar = 100 μm. b Pharyngeal epithelium without secondary bacterial infections (stained with Giemsa); scale bar = 10 μm. c Infected pharynx showing three parasites (arrows), one of them partially covered by the pharyngeal epithelium; scale bar = 100 μm. d Secondary bacterial infections (asterisks) in the pharyngeal epithelium associated with A. contortum infections (stained with Giemsa); scale bar = 10 μm. e. A. contortum with a specific eosinophilic compact outer layer in the epithelium in contact with the parasite forebody (arrow) (inset: detail of the layer (black diamond)); scale bar = 100 μm (inset 50 μm). f A. contortum hindbody (arrow) in contact with the pharyngeal epithelium; scale bar = 100 μm. Stained in H-E, except for (b and d)
