Cercariae and metacercariae of Stephanostomumcloacum (Trematoda: Acanthocolpidae)

International Journal for Parasitology, 1993
Cercariae and metacercariae of the acanthocolpid trematode, Stephanostomum cloacum (Srivastava, 1938) are described and illustrated, based on material collected from Chilka Lake, a brackish water lagoon. Natural infections with the cercariae were found in the snail, Nassarius orissaensis and with the metacercariae in the bivalve, Modiolus undulatus ...

Ecology of Free-Living Metacercariae (Trematoda)

2015
The presence of trematodes with a free-living metacercarial stage is a common feature of most habitats and includes important species such as Fasciola hepatica, Parorchis acanthus and Zygocotyle lunata. These trematodes encyst on the surface of an animal or plant that can act as a transport host, which form the diet of the target definitive host ...

The Early Development of the Daughter Sporocysts of the Strigeoidea (Trematoda)

The Journal of Parasitology, 1953
appear to be differences between species. However, there are rarely fewer than 12 or more than 30 in each sporocyst. The largest embryos of the germinal masses are at the ends and the production of free embryos in both mother and daughter sporocysts appears to be accomplished only by their breaking off.

Systematics, Taxonomy, and Nomenclature of the Trematoda

The Quarterly Review of Biology, 1963
Recent publications present diverse opinions concerning the classification and taxonmy of the Trematoda. Dollfus (1958b) adopted the system of Faust and Tang (1936), recognizing three subclases: Monogenea, Digenea, and Aspidogastrea. Baer and Euzet (1961) removed the Monogenea from the Trematoda and regarded the group as a separate and independent ...

Carbohydrate energy metabolism in Fasciola gigantica (trematoda)

International Journal for Parasitology, 1980
Abstract Umezurike G. M. and Anya A. O. 1980. Carbohydrate energy metabolism in Fasciola gigantica (Trematoda). International Journal for Parasitology10: 175–180. Adult Fasciola gigantica contained 4.49 ± 0.06 % (mean ± S.D.) wet weight glycogen. Tissue homogenates contained high levels of malate dehydrogenase (MDH), NAD-linked malic enzyme (ME),

Miracidial penetration inFascioloides magna (Trematoda)

Zeitschrift f�r Parasitenkunde Parasitology Research, 1981
The penetration of the miracidium of Fascioloides magna into the snail host Fossaria bulimoides is followed by examining the process at certain, timed intervals during the course of penetration. The cilia are lost early, but the epithelial cells may detach or they may be carried into the snail body.

Chemosensitivity of Philophthalmus megalurus (Trematoda) Miracidia

The Journal of Parasitology, 1990
Miracidia of the eyefluke Philophthalmus megalurus were tested in phi-chambers to determine if they reacted similarly to chemicals found stimulative for miracidia of Philophthalmus gralli, a closely related species. Philophthalmus megalurus miracidia were less responsive than P. gralli to the dicarboxylic amino acids and showed a significantly positive
