Scanning electron microscopic study of four Diphyllobothrium species.
Three-dimensional observation was carried out on plerocercoids and adults of Diphyllobothrium dendriticum, D. ditremum, D. latum, and D. vogeli using scanning electron microscopy. The species-specific differences between plerocercoids were recognized in the shapes of the whole body, scolex, and bothrium and the wrinkle pattern on the body surface. The differences between adult worms were also observed in the shapes of the scolex, neck, and genital papillae around the genital pore and the pattern on the egg surface. The significance of species specificity in the three-dimensional morphology of diphyllobothriid cestodes is briefly discussed.
