Histamine in the Phylum Platyhelminthes

The Journal of Parasitology, 1963
Six members of the phylum Platyhelminthes have been examined for histamine content. The free-living species studied contained no histamine, whilst the parasitic species studied contain appreciable amounts of histamine. No correlation could be found between the histamine content of a parasite and that of its host tissue.

The origins of parasitism in the platyhelminthes

International Journal for Parasitology, 1994
Symbiotic associations have arisen independently in several groups of the largely free-living turbellarians. Morphological adaptations of turbellarians to a symbiotic way of life include suckers and adhesive glands for attachment, elaborate systems of microvilli and other epidermal structures for absorption of food, glands for the formation of cysts ...

The Larvae of Monogenea (Platyhelminthes)

1999
There has been no comprehensive review of the infective larval stage (oncomiracidium) in the direct life-cycle of monogeneans since Llewellyn. In the last 30 years, knowledge of the general anatomy and morphology of oncomiracidia has increased significantly as has information on swimming behaviour and egg-hatching strategies that may enhance chances of

Adhesive secretions in the platyhelminthes

2001
This review is the first to draw together knowledge about bioadhesives secreted by a group of parasites. Mechanisms of mechanical attachment are well known among parasites, but some can also attach to host surfaces by chemical means using a thin layer of adhesive material secreted at the parasite-host interface.

Platyhelminthes: The Turbellarians

1973
Interest in the phylogenetic development of learning capacities must lead to heavy emphasis on the flatworm, since it is the primitive turbellarian form Acoela which is widely accepted as representing the beginnings of bilateral existence. Of critical significance at this phylogenetic point are the appearance of the bilateral form and the consistently ...
