ULTRASTRUCTURE DES MONOGÈNES: LISTES DES ESPÈCES ET DES ORGANES ÉTUDIÉS
TLDR
Bibliographical data concerning the ultrastructure of monogeneans in scanning electron microscopy (SEM) or transmission electron microscopeopy (TEM) are presented in two lists. Expand
Ultrastructure of spermiogenesis, spermatozoa and the tegument in Atriaster sp. (Platyhelminthes, Monogenea, Polyopisthocotylea, Microcotylidae)
TLDR
Spermiogenesis is similar to the general scheme in the Cercomeridae and particularly the polyopisthocotylean monogeneans, but shows two remarkable characteristics: the zone of differentiation for each spermatid is separated by a region without longitudinal microtubules but with many mitochondria, herein termed the pre‐zone of differentiation. Expand
Ultrastructure of the anterior adhesive apparatus of the gill parasite Macrogyrodactylus clarii and skin parasite M. congolensis (Monogenea; Gyrodactylidae) from the catfish Clarias gariepinus.
TLDR
TEM was used for the first time to study the anterior adhesive apparatus of the monogeneans Macrogyrodactylus clarii Gussev and M. congolensis inhabiting gills and skin respectively of the same catfish Clarias gariepinus and revealed that they have a similar anterior adhesive system. Expand
An ultrastructural study of the surface and attachment structures of Paradiplozoon homoion (Bychowsky & Nagibina, 1959) (Monogenea: Diplozoidae)
TLDR
The hypothesis that the structure of particular neodermal compartments is similar within the Platyhelminthes is supported, and the diplozoid glandular system and the mechanism of sclerite development clearly merits further attention is considered. Expand
Ultrastructural observations of the attachment organs of the monogenean Rajonchocotyle emarginata (Olsson, 1876) (Polyopisthocotylea: Hexabothriidae), a gill parasite of rays
TLDR
The ultrastructural features of the haptor are discussed in relation to the understanding of their function and the evolutionary relationships of the basal polyopisthocotylean monogenean groups Hexabothriidae and Chimaericolidae. Expand
Surface Topography of the Anterior Adhesive Apparatus of the Gill Monogenean Parasite Diplectanum sp. diesing, 1858, with some Surface Criteria
Surface topography of anterior adhesive apparatus was studied of the gill monogenean parasite Diplectanum sp. Diesing, 1858 inhabiting the marine water fish Dicentrachus sp. using SEM. The studyExpand
Histochemical demonstration of five enzymes' activities in Macrogyrodactylus clarii (Monogenea: Gyrodactylidae) from the catfish Clarias gariepinus.
TLDR
The distribution of the enzymes in the tissues and organs of M clarii is compared with those of other monogeneans, including other gyrodactylids parasitizing the same host fish. Expand
Surface features of the monogenean gill parasites Pseudodactylogyrus anguillae and Pseudodactylogyrus bini from the European eel Anguilla anguilla in Egypt
In the present study, scanning electron microscopy is used to demonstrate the surface features of Pseudodactylogyrus anguillae Yin and Sproston (1948) Gussev, 1965 and Pseudodactylogyrus bini KikuchiExpand
Comparative topography and ultrastructure of tegument in a polyopisthocotylean parasite (Metamicrocotyla cephalus) and a monopistho-cotylean parasite (Dactylogyrus extensus).
TLDR
The result showed that the tegument of M. cephalus is characterized by many foldings producing closely packed annular corrugations superimposed with a complex configuration of many robust papillae bearing microvillus-like projections, thin terminal web just underneath the apical plasma membrane. Expand
Scanning and transmission electron microscope studies on the sensory sucker papillae of the fish parasite Entobdella soleae (monogenea)
  • K. Lyons
  • Biology, Medicine
  • Zeitschrift für Zellforschung und Mikroskopische Anatomie
  • 2004
TLDR
The ventral surface of the posterior sucker of Entobdella soleae, a monogenean skin parasite of the sole Solea solea, is covered with more than 800 papillae, which may be contact receptors or strain receptors, providing proprioceptive information assisting the coordination of the attachment organ.

Comparative fine structure of outer tegument of Ligula intestinalis and Schistocephalus solidus.
TLDR
The outer tegument of Ligula, though basically similar to Schistocephalus, shows certain differences, even though the plerocercoids of each species occupy a similar environment, the fish body cavity. Expand

A presumed sensory structure associated with the tegument of Schistosoma mansoni.
TLDR
A sensory structure located in the tegument of Schistosoma mansoni adults is described, which consists of a bulb bearing an apical cilium which projects into the surrounding medium and is speculated that the unit may function to detect the direction of flow of the surroundingmedium. Expand
CORRELATION BETWEEN THE PRESENCE OF SULFATED POLYSACCHARIDES AND MINERALIZATION IN A MARINE COCCOLITHOPHORID PROTOZOON: HISTOCHEMICAL AND AUTORADIOGRAPHIC STUDIES
TLDR
Observations suggest that, even at the level of an evolving mechanism, sulfur-containing carbohydrates participate in some manner in the deposition of mineral onto a preformed organic matrix. Expand

  • 1967
TLDR
The cestode, Hymenolepis diminuta, has been tested for its capacity to transport either colloidal carbon, colloidal ferritin, or colloidal thorium dioxide and the mechanism of transport is conjectural, and considered to be pinocytosis. Expand
ELECTRON MICROSCOPE OBSERVATIONS ON THE CARBOHYDRATE-RICH CELL COAT PRESENT AT THE SURFACE OF CELLS IN THE RAT
TLDR
Findings indicate that the stained layer is a "cell coat" located outside the plasma membrane, since the cell coat is also stained by colloidal thorium, a technique for detection of acidic carbohydrates, this structure presumably contains not only glycoprotein but also acidic residues. Expand
FUNCTIONS OF COATED VESICLES DURING PROTEIN ABSORPTION IN THE RAT VAS DEFERENS
TLDR
Large coated vesicles serve as heterophagosomes to transport absorbed protein to lysosomes, and some small coated vedicle serve as primary lysOSome to transport hydrolytic enzymes from the Golgi complex to multivesicular bodies. Expand
