Ultrastructural characters of the spermatozoon of the digenean Hypocreadium caputvadum Kacem et al., 2011 (Lepocreadioidea: Lepocreadiidae), an intestinal parasite of Balistes capriscus in Tunisia.
TLDR
The electron-dense material surrounding one of the axonemes in the anterior spermatozoon extremity constitutes the unique distinguishing ultrastructural character of lepocreadioideans, and it is present in spermatozoa of lePocreadiids, aephnidiogenids and gyliauchenids. Expand
Spermiogenesis and spermatozoon ultrastructure of the digenean Neoapocreadium chabaudi (Apocreadiidae), a parasite of Balistes capriscus (Pisces, Teleostei).
TLDR
The present paper provides the first ultrastructural results of a digenean belonging to the family Apocreadiidae that may be useful for the understanding of digenesan relationships and phylogenetic studies. Expand
Total mercury and selenium concentrations in Sarpa salpa and Balistes capriscus and in their respective Digenean endoparasites Robphildollfusium fractum and Neoapocreadium chabaudi from Tunisia
TLDR
The present results confirm that the habitual consumption of S. salpa should not suppose any potential health risk for Tunisian people and that the consumption of B. capriscus may be of concern and further monitoring is advisable, since the Hg average concentration in Mahdia was above the maximum allowed Hg concentration in the edible portion of fish fixed by the European Union.

Functional ultrastructure and cytochemistry of vitellogenesis and mature vitellocytes of the digenean Cainocreadium labracis (Dujardin, 1845), parasite of Dicentrarchus labrax (L., 1758)
TLDR
General pattern and functional ultrastructure of vitellogenesis greatly resemble those observed in some lower cestodes, such as bothriocephalideans and diphyllobothrideans. Expand
The Opecoelidae sperm model and its contribution to phylogeny: spermatozoon ultrastructural particularities of Allopodocotyle pedicellata (Plagioporinae, Digenea, Platyhelminthes)
TLDR
The sperm model is established for the Opecoelidae and it is compared to mature spermatozoa of other digeneans, particularly those belonging to the family Opistholebetidae and the superfamilies Allocreadioida and Brachycladioidea or their related sister groups. Expand
Ultrastructure of the spermatozoon of the digenean Tergestia acanthocephala (Stossich, 1887) (Gymnophalloidea: Fellodistomidae): An intestinal parasite of Belone belone gracilis (Pisces: Teleostei).
TLDR
The ultrastructural organization of the spermatozoon of the digenean Tergestia acanthocephala (Gymnophalloidea: Fellodistomidae) is described and corresponds to the fasciolidean type of Quilichini et al. (2010a). Expand
Ultrastructure of the spermatozoon of Macvicaria obovata (Digenea: Opecoelidae), a parasite of Sparus aurata (Pisces: Teleostei) from the Gulf of Gabès, Mediterranean Sea
TLDR
New data is provided on the mature male gamete of M. obovata that may be useful for the understanding of digenean relationships and phylogenetic studies. Expand
Sperm characters of the bucephalid digenean Prosorhynchoides arcuatus and their phylogenetic significance
TLDR
The ultrastructural study reveals that the mature spermatozoon of P. arcuatus is a filiform cell which is tapered at both extremities and exhibits the Bakhoum et al. Expand
Ultrastructural organisation of the spermatozoon of Allopodocotyle tunisiensis Derbel and Neifar, 2009 (Digenea, Opecoelidae), an intestinal parasite of Solea aegyptiaca Chabanaud, 1927 (Teleostei,
TLDR
The ultrastructure of the spermatozoon of Allopodocotyle tunisiensis (Digenea, Opecoelidae), an intestinal parasite of Solea aegyptiaca, is described by transmission electron microscopy (TEM). Expand
Ultrastructure of the spermatozoon of Centroderma spinosissima (Stossich, 1886) (Digenea: Mesometridae) and its phylogenetic potential.
TLDR
The ultrastructure of the spermatozoon of a third genus and third species of Mesometridae, Centroderma spinosissima, is revealed and the presence of cytoplasmic ornamented buttons is a characteristic found only in the mature spermatoZoon of mesometrids and it probably represents an autapomorphy for this family.
