Species differentiation in the didymozoidae (Digenea): Restriction fragment length differences in internal transcribed spacer and 5.8S ribosomal DNA

International Journal for Parasitology, 1993
Genetic differences among six didymozoid species distinguished on morphological criteria (Didymozoon species A, B, E, F and G, and Neometadidymozoon helicis) were sought by restriction fragment length analysis of internal transcribed spacer (ITS) and 5.8S ribosomal DNA.

A new genus and species of the Didymozoidae (Digenea) from the skipjack tuna Katsuwonus pelamis (L.) (Scombridae)

Systematic Parasitology, 2012
A new genus and species of didymozoid digenean is described from the skipjack tuna Katsuwonus pelamis (Linnaeus) in the Southwest Atlantic Ocean off Brazil. Pozdnyakovia gibsoni n. g., n. sp. is placed in the Gonapodasmiinae Ishii, 1935. The new genus differs from other genera in the morphology of the posterior regions of the fused pair; this consists ...

Genetic variability in members of Didymozoidae family isolated from two bluefin tuna species

2007
Atlantic (Thunnus thynnus) and Pacific bluefin tuna (Thunnus orientalis) are migratory marine teleosts that are declining in abundance due to overexploitation in the Atlantic and Mediterranean Sea. Recently, molecular and electronic tag data has shown that at least two populations exist in the North Atlantic and mix on foraging grounds in the North ...

Rhopalotrema (Digenea: Didymozoidae), a new genus from Australian platycephalid fishes

Systematic Parasitology, 1998
Rhopalotrema n. g. is erected to accommodate two new species of didymozoid collected from platycephalid fishes from South-east Queensland, Australia and is assigned to the subfamily Didymozoinae. Rhopalotrema elusiva n. sp. is described from the fins of Platycephalus fuscus and R. pterygionastes n. sp. is described from the fins of P. indicus.

Evidence that host ecology drives first intermediate host use in the Didymozoidae (Trematoda: Hemiuroidea): an asexual infection in a vermetid (Gastropoda)

Journal of Helminthology, 2022
Abstract The Didymozoidae (Trematoda: Hemiuroidea) is among the most speciose trematode families, known from a wide range of marine teleost fishes. Despite their richness, however, didymozoid life cycles are unusually poorly known; only two first intermediate hosts are known, a marine bivalve (Anadara trapezia) and a pelagic gastropod (Firoloida ...

Detection and molecular analysis of Philopinna higai (Digenea: Didymozoidae) from domestically introduced Sarcocheilichthys fishes in the Tohoku region, Japan

Parasitology International, 2023
Philopinna higai is a species of Didymozoidae (Digenea: Hemiuroidea). The definitive hosts of this parasite only belong to the fish genus Sarcocheilichthys. Sarcocheilichthys fishes are endemic to Lake Biwa and southwestern Japan and were introduced into the northeastern (Tohoku) region. However, P.

Gonapodasmius epinepheli n. sp. (Didymozoidae) from the grouper Epinephelus tauvina from the Arabian Gulf

Systematic Parasitology, 1990
A new species, Gonapodasmius epinepheli (Didymozoidae: Gonapodasmiinae), is described from the fish Epinephelus tauvina from the Arabian Gulf. It differs from most other members of the genus in the presence of a bulbous swelling at the distal end of the ovary, the presence of a characteristic bulge in the genital junction region, in the dense mass of ...

[New trematode genus of the family Didymozoidae from a mackerel in the Indian Ocean].

Parazitologiia, 1979
A new trematode of the genus Paranema tobothrium triplovitellatum gen. et sp. n. from the body cavity of Scomber scombrus from the Indian ocean is described. The individuals of the new genus are not incysted. Testes paired, ovary twisted, unbranched, vitelline gland bifurcates, uterus forming three turns.

On an Immature Didymozoid Larva (Trematoda: Didymozoidae) in the Muscles and Swim Bladder of Anthias squamipinnis (Anthiidae) from the Gulf of Aqaba

The Journal of Parasitology, 1972
An immature didymozoid larva, designated Immature Didymozoid H, is described from the dorsal muscles and swim bladder of Anthias squamipinnis (Peters), a coral-reef fish caught in the Gulf of Aqaba near Eilat. This larva is considerably larger than any didymozoid larva previously described.
