Spermiogenesis and sperm ultrastructure of two species of Duthiersia, parasites of monitors, with a review of spermatological characters in the Diphyllobothriidea (Cestoda)
Original language description
The present study compares the spermiogenesis of two species of the diphyllobothriidean cestodes (family Scyphocephalidae), Duthiersia expanse and Duthiersia fimbriata, parasites of Asian and African monitors (Varanus spp.), and establishes the ultrastructural organization of the spermatozoon of D. fimbriata. The spermatids of both species are similar and exhibit a differentiation zone containing two centrioles and electron-dense material in the apical region. The centrioles are separated from one another by an inter-centriolar body and each is associated with a striated root. During the early stage of spermiogenesis, the centrioles form two flagella that grow orthogonally to the median cytoplasmic process. The orthogonal development is followed by a flagellar rotation and proximodistal fusion with median cytoplasmic process. The mature spermatozoon of D. fimbriata is characterized by the presence of two axonemes presenting the type 9+ "1" trepaxonematan pattern, parallel cortical micr
