Form and Function in the Digenea

2019
This review aims at covering the general aspects of the form and function of the major body systems in digenetic trematodes, with emphasis on the advances that have been made on this topic since the publication of the first edition of this book; this is since 2012.

Phylogeny and classification of the Digenea (Platyhelminthes: Trematoda).

International journal for parasitology, 2003
Complete small subunit ribosomal RNA gene (ssrDNA) and partial (D1-D3) large subunit ribosomal RNA gene (lsrDNA) sequences were used to estimate the phylogeny of the Digenea via maximum parsimony and Bayesian inference. Here we contribute 80 new ssrDNA and 124 new lsrDNA sequences.

The diversity of the Digenea of Australian animals

International Journal for Parasitology, 1998
The Digenea is one of five major helminth assemblages represented in Australian animals. History of the study of digeneans in Australia is reviewed briefly to show that it has never been subjected to the kind of sustained study needed to reach an understanding of it. The Australian vertebrate fauna comprises over 5500 species.

The evolutionary expansion and host-parasite relationships of the Digenea

International Journal for Parasitology, 1994
Relevant data on the Digenea extracted from a host-parasite data-base are analysed in relation to host-groups, host-specificity, speciation, radiation and geographical distribution. The classification, evolution, co-evolution, and co-speciation of the group are discussed.

Interpretation of life history pattern in the Digenea

International Journal for Parasitology, 1974
Abstract The nature of secondary multiplication in the Digenea, especially in the molluscan host is reviewed. The concepts of alternation of generations and polyembryony are examined and discarded as unhelpful. In the absence of both meiosis and recognizable ovaries in miracidia, sporocysts and rediae, there are no criteria for distinguishing diploid

Thetines and Betaines of the Red Alga Digenea simplex

Journal of Natural Products, 1993
From the aqueous extract of the red alga Digenea simplex, seven Dragendorff-positive compounds have been isolated and their structures determined by spectral and chemical methods. The taxonomic significance of their occurrence and possible biosynthetic relationships between some of these compounds are also discussed.

Control of Swimming in Cercariae of Proterometra macrostoma (Digenea)

The Journal of Parasitology, 1983
A specific acetylcholinesterase (AChE) was localized histochemically in Proterometra macrostoma cercariae. This esterase activity was inhibited by eserine, but was resistant to tetraisopropyl pyrophosphoramide. A transverse band of intense AChE activity was observed in the posterior region of the tail.

Opistholobetines (Digenea: Opecoelidae) in Australian tetraodontiform fishes

Systematic Parasitology, 2018
Opistholebetine opecoelids are reported following examination of 1,041 individual tetraodontiform fishes, comprising 60 species and seven families, collected in Australian waters between 1986 and 2018. Nine species consistent with Opistholebes Nicoll, 1915, Heterolebes Ozaki, 1935 or Maculifer Nicoll, 1915 were recovered. However, phylogenetic analysis

Sporocysts of Mesostephanus haliasturis (Digenea) produce miracidia

International Journal for Parasitology, 1993
This is the sixth report of a trematode that produces miracidia in its Sporocysts. Experimentally, we induced transmission of this parasite from snails to fish to cormorants. Thus, adult specimens were obtained and the species identified for the first time.
