Gross findings and parasitology, (a) Gastrointestinal tract from a 6-year-old female European pond turtle (Emys orbicularis, ID8) displaying large numbers of spirorchiid eggs in the subserosal vessels (arrowheads), which are more visible in the intestine. Note the focal stricture of the intestine (arrow) with proximal severe dilation. This section was filled with a large amount of necrotic material. Bar 1 cm. (b) Autolytic testis from ID5 displaying similar lesions to the ones observed in the gastrointestinal tract from ID8 (arrowheads). Bar 25 mm. (c) Aspect of a spirorchiid egg stained with methylene blue identified following sedimentation from intestinal content. Light optical microscope, Bar 10 μm.
