Degenerating epidermal cells in Xenoturbella bocki (phylum uncertain), Nemertodermatida and Acoela (Platyhelminthes
Chromsome polymorphism and complements in populations of Girardia species (Platyhelminths
, Tricladida, Paludicola) from southern Brazil.
The phylum platyhelminths
, flatworms, are composed of Cestoda, Trematoda and Turbellaria, and they are the lowest animals that exhibit the cephalization and distinguishable central and peripheral nervous system.
There is little experimental evidence to suggest the functions of the various types of receptors found in Platyhelminthes
but all functional interpretations of presumed sensory structures remain uncertain and are based solely on their distribution and ultrastructural anatomy and are therefore speculative.
: Rhabdocoela) on clams from the northern Patagonian coast, Argentina: pathogeny and specificity.
Planarians are free-living freshwater flatworms belonging to the phylum Platyhelminthes
. They have a primitive morphology with simple triploblastic bodies (based on body-plan categories).
Three echinoderm-inhabiting flatworms (Platyhelminthes
, Rhabdocoela) from western Australia.
In an asexual race of Dugesia tigrina (platyhelminth
), lost body regions are defined during regeneration by Hox genes that have sequences very similar to those found in annelids (Bayascas et al., 1998).
round worms or nematodes including intestinal worms, filarial worms that cause lymphatic filariasis, chocerciasis, platyhelminths
or flatworms including flukes, and tapeworms.
Larval and adult platyhelminths
and Acanthocephala were fixed in alcohol-formalin-acetic acid (AFA), stained with acetic carmine, and mounted in Canada balsam.
Analyses of DNA sequences in the protein's codifying and non-codifying regions, have been largely used in phylogenetic studies on fish helminths parasites (Clark, 2006), with special reference to investigations on the three main Platyhelminthes
groups: Cestoda, Digenea and Monogenea.
