Didymozoidae from platycephalid fishes of Moreton Bay [PDF]

, 2022
Nine new species of didymozoid (Platyhelminthes, Digenea) are described from five species of platycephalid (flathead) fish collected in Moreton Bay, Australia. They are: lndodidymozoon moretonensis sp. n. from the buccal cavity and branchial arch'es, I suttiei sp. n. from the skeletal muscles, and Rhopalotrema elusiva gen. n., sp. n.

Atypical spermiogenesis in a parasitic flatworm, Didymozoon (trematoda: digenea: didymozoidae)

Journal of Ultrastructure Research, 1984
Spermiogenesis in trematodes usually involves the formation in the spermatid of a characteristic structure, a protuberance called the zone of differentiation. This structure was not found in Didymozoon. Instead, spermiogenesis in Didymozoon consists of an elongation of the whole spermatid.

Ultrastructure of Didymocystis semiglobularis (Didymozoidae, Digenea) cysts in the gills of Pacific bluefin tuna (Thunnus orientalis)

Parasitology Research, 2008
Tuna are active pelagic fish with an extraordinary migratory activity, well known for their unique physiology reflected in high metabolic rates. However, knowledge of microbial and environmental diseases is still limited. We have analyzed the ultrastructure of the digenean trematode Didymocystis semiglobularis isolated from the gill arch of Pacific ...

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 ...

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.

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 ...

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.
