Ultrastructural study of the spermatozoon of Heterolebes maculosus (Digenea, Opistholebetidae), a parasite of the porcupinefish Diodon hystrix (Pisces, Teleostei).
TLDR
The similarity between the spermatozoon of the Opistholebetidae H. maculosus and Opecoelidae enables us to confirm that these two families are closely related. Expand
Ultrastructural study of the spermatozoon of Pronoprymna ventricosa (Digenea, Baccigerinae), parasite of the twaite shad Alosa fallax Lacepede (Pisces, Teleostei)
TLDR
The ultrastructural organisation of the spermatozoon of a Digenea Baccigerinae Pronoprymna ventricosa is described and a separation in two groups of the digenean spermatozoa is proposed in relation to the localisation of the external ornamentations. Expand
ULTRASTRUCTURAL STUDY OF SPERMIOGENESIS AND THE SPERMATOZOON OF CREPIDOSTOMUM METOECUS (DIGENEA: ALLOCREADIIDAE), A PARASITE OF SALMO TRUTTA (PISCES: TELEOSTEI)
TLDR
Spermiogenesis and the spermatozoon of Crepidostomum metoecus, an intestinal parasite of brown trout Salmo trutta, were studied by transmission electron microscopy, the first undertaken with a species of the Allocreadiidae. Expand
Spermatozoon ultrastructure of Aponurus laguncula (Digenea: Lecithasteridae), a parasite of Aluterus monoceros (Pisces: Teleostei).
TLDR
This study is the first undertaken with a member of the Lecithasteridae and exemplifies the sperm ultrastructure for the superfamily Hemiuroidea. Expand
SPERMIOGENESIS AND SPERMATOZOON ULTRASTRUCTURE OF NICOLLA WISNIEWSKII (DIGENEA: OPECOELIDAE), AN INTESTINAL PARASITE OF BROWN TROUT SALMO TRUTTA (PISCES: TELEOSTEI)
TLDR
It appears that the number of cortical microtubules and their localization in the spermatozoon may be an interesting feature of their phylogeny. Expand
Spermiogenesis and sperm ultrastructure of Deropristis Inflata Molin, 1859 (Digenea, Deropristidae), a parasite of Anguilla anguilla
TLDR
The ultrastructural investigations produce new data on the reproduction of D. inflata, which may be useful for the understanding of the phylogenetic relationships in the Deropristidae family. Expand
Topography and Ultrastructure of the Tegument of Bucephalus anguillae (Digenea: Bucephalidae), a Parasite of the European Eel Anguilla anguilla (Osteichthyen: Anguillidae)
TLDR
Ulastructural study revealed that the tegument of B. anguillae has a typical syncytial organization with a distal cytoplasm lying over a basal matrix and cytons below, allowing transit of secretory vesicles and granules. Expand
Ultrastructural study of the spermatozoon of Nicolla testiobliquum (Digenea, Opecoelidae) parasite of brown trout Salmo trutta (Pisces, Teleostei)
TLDR
It appears that the organisation of the posterior part of the spermatozoon, the disposition of cortical microtubules and external ornamentation associated with spine-like bodies could be interesting elements for phylogeny. Expand
Sperm ultrastructure of the gall bladder fluke Anisocoelium capitellatum (Digenea: Cryptogonimidae), a parasite of Uranoscopus scaber (Pisces: Uranoscopidae)
TLDR
The male gamete presents features allowing the distinction between A. capitellatum and other digenetic trematodes, characterized by original anterior and posterior extremities. Expand
Effect of duration of feed withdrawal and transportation time on muscle characteristics and quality in Friesian-Holstein calves.
TLDR
An unfavorable effect of long transport on the sensory quality of veal is demonstrated and cannot be explained on the basis of differences in pH values and(or) compositional characteristics. Expand
