The paramphistomes (Trematoda) of Australian ruminants.

Australian Journal of Zoology, 1953
A description of the development at 27 C. of Ceylonocotyle streptocoelium (Fischoeder 1901) Nasmark 1937, a paramphistome from the rumen and reticulum of sheep and cattle in Australia, is given in detail. Eggs hatched after 16 days' incubation and miracidia penetrated the intermediate host, a planorbid snail, Glyptanisus gilberti Dunker 1848 ...

Systematic Analysis of the Diplostomidae and Strigeidae (Trematoda)

The Journal of Parasitology, 1989
A systematic analysis of the genera in the Diplostomidae and Strigeidae was made using the Proterodiplostomidae as the outgroup. The Proterodiplostomidae was the family with the greatest preponderance of primitive characters and its monophyly was supported by the unique paraprostate gland.

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 ...

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.

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 ...

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 ...
