Morphological Characterization of Emerging Cercariae among Lymnaeid Snails from Barangay Cawongan, Padre Garcia, Batangas, Philippines

Figure 3

Microscopic images of different types of cercariae that emerged from lymnaeid snails (CX 21, 400x magnification). (1)-(2) Echinostome cercariae. A collar of spines in the oral sucker is noted. Upper image shows the complete larvae, while the lower image shows the de-tailed part of the body. (3)-(4) Virgulate xiphidiocercaria. Take note of defined stylet present in the anterior-most part of the oral sucker. (5)-(6) Longifurcate-pharyngeate distome cercariae (Strigea cercariae). Excretory pores are seen along the midportion of the bifurcated tail.
