The effects of cardamonin on the tegument
of schistosomes were analyzed by confocal microscopy analysis in order to examine morphological alterations at the surface of male worms.
According to Bartoli (1974), a gymnophallid cercaria can be identified by the following characteristics: Distome, pharyngeate larva, tegument
spinose, eyespots absent, stylet lacking, excretory vesicle thin-walled V or Y shaped, furcated tail, developing in marine bivalves.
between spines can also be seen to have numerous pores or pits (Fig.
34), and sculpturing of tegument
as described in the third instar.
In contrast to PZQ, which causes an increase in the permeability of the membranes of schistosome cells leading to calcium-producing sustained muscular contraction, spastic paralysis and tegument
damage (Doenhoff et al.
The nut is oily, edible and covered by a thin tegument
layer (ALMEIDA et al.
According to these authors, adult individuals of this isopod occur in gills, tegument
or mouth of catfishes and armored catfishes, whereas young individuals are active free swimmers.
They have a whip shaped tail in which base there is a swing or a harpoon composed by dentine with a tegumentary case dentin shaped, saw profile and poisonous glands in the cuneiform area of the tegument
The virus has a capsid surrounded by a tegument
and a glycoprotein envelope.
Ultrastructural studies on the tegument
of the metacercariae of Meiogymnophallus minutus and Meiogymnophallus fossarum (Digenea: Gymnophallidae) in Cerastoderma edule (Bivalvia) from Portugal.
Electron micrograph studies of B virus show a typical herpesvirus structure (6), including an electron dense core with viral DNA inside an icosapentahedral capsid surrounded by an amorphous tegument
protein layer and a lipid envelope studded with viral glycoproteins.
