New data on the occurrence of Acanthocephala in Antarctic Amphipoda
In total, 6401 amphipods, including 5707 Cheirimedon femoratus, caught at the Galindez Island, were examined for the presence of cystacanths and advanced acanthellae of Acanthocephala, and the representative of the genus Metacanthocephalus was found in the intermediate host for the first time.
Changes in digenean infection of the Antarctic fish Notothenia coriiceps in Admiralty Bay, King George Island, over three decades
It is demonstrated that infections with almost all digenean species were less strong in 2007/08 than three decades earlier, in 1978/79.
Molecular characteristics of representatives of the genus Brachylecithum Shtrom, 1940 (Digenea, Dicrocoeliidae) with comments on life cycle and host specificity
Cercarial and metacercarial isolates from the snails showed 100 % similarity to B. lobatum; thus, it is the first record of Cepaea snails as intermediate hosts of this species and the first report on life cycle abbreviation within the Dicrocoeliidae.
Larval ascaridoid nematodes (Anisakidae) in fish from the South Shetland Islands (Southern Ocean)
The parameters of infection of Notothenia coriiceps and Lepidonotothen nudifrons by Pseudoterranova decipiens were decreasing within the 30 years period.
Acanthocephalans in Sub-Antarctic and Antarctic
Acanthocephalans (spiny head worms) are a medium-sized phylum (about 1000 species have been described) of usually small (few mm to over 1m) vertebrate intestinal parasites with reduced the muscular, nervous, circulatory, and excretory systems and complete loss of the digestive system.
A phylogenetic analysis of trematodes of the genus Echinoparyphium and related genera based on sequencing of Internal Transcribed Spacer region of rDNA
The sequencing of ITS 1 fragments of the rDNA were assayed in order to discriminate species and to estab­lish relationships between representatives of the genus Echinoparyphium and to identify sympatric sibling species within the 45 collar spine Echino­paryPhium.
The helminth fauna of some notothenioid fishes collected from the shelf of Argentine Islands, West Antarctica
The presently reported study have confirmed that the south range of distribution of two acanthocephalans, Aspersentis megarhynchus and Coryno− soma hamanni extends south to the area near the Argentine Islands.
Cystacanths of Acanthocephala in notothenioid fish from the Beagle Channel (sub-Antarctica)
The morphology of relaxed cystacanths of polymorphid acanthocephalans collected from notothenioid fishes in the Beagle Channel (Magellanic subregion of sub-Antarctica) is described. A parasite of
