The surface microtopography of Calicophoron papillosum (Stiles & Goldberger) and C. calicophorum (Fischoeder), inhabiting the rumen of sheep, has been studied by SEM. In C. papillosum, conspicuous transverse ridges encircle the mid-body, gradually lessening dorsally towards the posterior end. The general body surface is aspinose and smooth except for minute bead-like tubercles in the circumoral area. Two types of putative sensory structures-domed aciliate papillae and tegumental pits-are… Expand
Light microscopy and surface topography of Urotrema scabridum and Renschetrema indicum (Digenea) from Rhinopoma hardwickii (Chiroptera): first report in Egypt.
TLDR
The recovered helminthes were studied morphologically and morphometrically by light microscopy and the surface topography of the two species was elucidated by scanning electron microscopy (SEM). Expand
Ultrastructural and histochemical observations on the tegument of Gastrodiscoides hominis (Paramphistoma: Digenea).
TLDR
The tegument of the paramphistome, Gastrodiscoides hominis, is folded into concentrically arranged furrows and ridges bearing numerous tightly packed tubercules, and extends into the oral cavity. Expand
Analysis of the Tegument of Zygocotyle lunata (Trematoda: Paramphistomidae) Adults by Scanning Electron Microscopy
TLDR
It is asserted that the newly recognized morphological features should be used for species differentiation in the future in addition to the new molecular techniques. Expand
Scanning electron microscopy of adult Dicrocoelium dendriticum
TLDR
The authors suppose that the vesicles and finger-like projections of the tegument may well be the same structure in different functional stages, and some considerations on the significance of the Tegumental differences in each body region are given. Expand
Tegumental surface changes in adult Paramphistomum microbothrium (Fischoeder 1901) following in vitro administration of artemether
TLDR
In vitro effects of artemether on adult Paramphistomum microbothrium were evaluated, for the first time, using scanning electron microscopy and damage to both oral sucker and acetabulum was so extreme that little recognizable structure remained. Expand
Ultrastructural and cytochemical observations on the tegument of three species of paramphistomes (Platyhelminthes:Digenea) from the Indian water buffalo, Bubalus bubalis.
TLDR
Mitochondria are absent from the adult surface syncytium and tegumental cells, suggesting that the teguments of the paramphistomes Gigantocotyle explanatum, Srivastavaia indica and Gastrothylax crumenifer is largely protective in function and probably has limited absorptive potential. Expand

Scanning electron microscopic observations have been made on the tegument and body pores of the wormIsoparorchis hypselobagri (Billet 1898) Odhner 1927, collected from the air bladder of theExpand
Gigantocotyle explanatum: scanning electron microscopic studies on the topographical effects of certain anthelmintics in vitro.
TLDR
The surface papillae apparently represent distinct target sites for the action of certain anthelmintics that damage the body surface, but the nature and degree of damage varied in each case. Expand
Gastrothylax crumenifer: ultrastructure and histopathology study of in vitro trematodicidal effect of Microlepia speluncae (L.) Moore
TLDR
In vitro incubation study revealed death of all trematodes, lethal at 10 min incubation time at 5 mg/ml concentration, indicated RM value is 0, very much effective than Oxyclozanide, RM value was 0. Expand

TLDR
The critical-point-dried specimens of Gastrothylax crumenifer and Paramphistomum epiclitum, both recovered from the rumen of sheep, were studied by scanning electron microscopy at magnifications ranging from 10 to 10,000x to reveal the structural differences of the tegument between the two species.

Abstract The tegumental surface of Megalodiscus temperatus forms cobblestonelike areas with rows of indentations encircling the worm. This pattern merges in several areas into folds and ridges, someExpand
The tegumental surface of Phyllodistomum conostomum (Olsson, 1876) (Digenea), revealed by scanning electron microscopy
Abstract The external surface of P. conostomum is characterized by relatively large ridges encircling the anterior part of the worm at regular intervals. On the posterior part depressions on theExpand
A scanning electron microscopic investigation of the outer surfaces of Gorgoderina attenuata
TLDR
The external surface of Gorgoderina attenuata is characterized by ridges that encircle the worm at regular intervals and protuberances that give a beaded appearance to the tegumental surface. Expand
Scanning electron microscopy of integumental surface of schistosoma mansoni.
TLDR
The surface microtopography of the adult S. mansoni as visualized with the scanning electron microcope (SEM) provides a means for determining the fine topography of body surfaces and an opportunity is afforded to correlate external features with those internal structures revealed by TEM. Expand
The host-parasite interface of strigeoid trematodes. IX. A probe and transmission electron microscope study of the tegument of Diplostomum phoxini Faust, 1918.
TLDR
A combined study using Stereoscan and transmission electron microscopy has revealed the existance of surface specialisation of the adhesive organ of adult Diplostomum phoxini Faust, 1918 and demonstrated the presence of non-specific acid phosphatase activity in the walls of the chambers, in the microvilli and in the cisternae of the gland cell endoplasmic reticulum.

Surface features, sensory structures, and movement of the newly excysted juvenile Fasciola hepatica L.
TLDR
Three types of presumed sensory endings were distinguished by scanning electron microscopy: a ciliated type, a domed type, and a pit, which had a ciliary basal body and rootlet but it lacked a cilium. Expand
Scanning electron microscope observations on adult Schistosoma japonicum.
TLDR
The integumental surfaces of critical point dried adult Schistosoma japonicum were studied by scanning electron microscopy and found that the female is ridged and pitted and possesses fewer spines than in the oral sucker, the ventral sucker, and the gynecophoric canal of the male. Expand
Scanning electron microscopy of the integumental surfaces of Schistosoma haematobium.
TLDR
The integumental surfaces of critical point dried S. haematobium were studied by scanning electron microscopy at 34 to 8,000 magnifications and revealed certain basic features such as spines in the oral sucker and the acetabulum of both sexes which may facilitate rasping and/or attachment of the parasite for residence in the bloodstream of the definitive host.

Scanning electron microscopy of Fasciola hepatica L. during growth and maturation in the mouse.
TLDR
Throughout the entire life of the fluke the spines anterior to the ventral sucker are arranged in approximately 60 rings each of 60 to 70 spines, but just prior to entry into the bile ducts, all spines have metamorphosed from single pointed to multipointed forms by division at the spine tips.
