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.

First record in South America of Koellikerioides internogastricus (Digenea, Didymozoidae) with new host record and pathological alterations

Veterinary Parasitology, 2009
The study of different species of tunas has revealed high numbers of cysts of Koellikerioides internogastricus Yamaguti, 1970, parasitizing Thunnus atlanticus (Lesson), Thunnus albacares (Bonnaterre) and Thunnus obesus (Lowe), caught along the Rio de Janeiro coastline, Atlantic Ocean, Brazil.

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.

Neonematobothrium annakohnae n. sp. (Digenea: Didymozoidae) parasitizing Euthynnus alletteratus (Perciformes: Scombridae) in the Southwest Atlantic Ocean

Acta Parasitologica, 2021
Describe a new species of didymozoid digenean Neonematobothrium Yamaguti, 1965 from the operculum of the scombrid fish, Euthynnus alletteratus (Rafinesque, 1810), in the Southwest Atlantic Ocean off Brazil.Thirty-four specimens of E. alletteratus were collected in the coastal zone of the state of Rio de Janeiro and obtained from local fishermen between

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 ...
