Novel gene arrangement in the mitochondrial genome of Aspersentis megarhynchus (Acanthocephala, Echinorhynchida, Heteracanthocephalidae), and its phylogenetic implications [PDF]

Parasite
The Heteracanthocephalidae Petrochenko, 1956 is a rare family of acanthocephalans mainly parasitic in fishes. The pattern of mitogenomic evolution of the Heteracanthocephalidae is still unknown, and the phylogenetic relationships of the ...

Molecular evidence on phenotypic variation in the poorly known acanthocephalan species Rhadinorhynchus cololabis Laurs & McCauley, 1964 (Echinorhynchida: Rhadinorhynchidae) [PDF]

Parasite
Acanthocephalans of the genus Rhadinorhynchus parasitize various marine fishes worldwide. However, the true diversity of Rhadinorhynchus is still unclear.

Ovarian balls (Floating ovaries) of Rhadinorhynchus niloticus Mohamadain, 1989 from the Nile perch Lates niloticus Linnaeus, 1758; an electron microscope study [PDF]

Helminthologia
In Acanthocephala, the ovarian balls (floating ovaries) are distinctive structures found suspended in the fluid-filled metasoma of females and are responsible for egg production and maturation.

First insight into metal binding proteins from the de novo transcriptome of acanthocephalan parasite Dentitruncus truttae [PDF]

Scientific Reports
Acanthocephala are parasites increasingly used as bioindicators of environmental quality due to their ability to effectively accumulate metals. However, the mechanisms of metal homeostasis in them remain unclear as there has been only one genomic study ...

Hooking the scientific community on thorny-headed worms: interesting and exciting facts, knowledge gaps and perspectives for research directions on Acanthocephala

Parasite, 2023
Although interest in Acanthocephala seems to have reached only a small community of researchers worldwide, we show in this opinion article that this group of parasites is composed of excellent model organisms for studying key questions in parasite ...

Genomics and transcriptomics of epizoic Seisonidea (Rotifera, syn. Syndermata) reveal strain formation and gradual gene loss with growing ties to the host

BMC Genomics, 2021
Background Seisonidea (also Seisonacea or Seisonidae) is a group of small animals living on marine crustaceans (Nebalia spec.) with only four species described so far. Its monophyletic origin with mostly free-living wheel animals (Monogononta, Bdelloidea)

Parasites of Moroccan desert Coptodon guineensis (Pisces, Cichlidae): transition and resilience in a simplified hypersaline ecosystem

Parasite, 2022
Sebkha Imlili (Atlantic Sahara) is a salt flat with over 160 permanent holes of hypersaline water generated in the Holocene and inhabited by euryhaline organisms that are considered to be relics of the past, including the cichlid fish Coptodon guineensis.

Endohelminth fauna of teleost fishes from coasts of Şile region of the Black sea

Helminthologia, 2021
A total of 508 fish specimens belonging to 19 species collected in the coast of Şile region of the Black sea were examined to detect the presence of endohelminths. Of this, 357 (70.27%) were found to be infected with parasites.

A comparative assessment of the morphology of Profilicollis altmani (Acanthocephala, Polymorphidae) from crustaceans and shore birds in Peru, with special notes on hook elemental analysis (EDXA), SEM imaging, histopathology, and molecular profile

Parasite, 2022
The morphology of cystacanths and adults of Profilicollis altmani (Perry, 1942) Van Cleave, 1947 (Polymorphidae) were studied from the Pacific mole crab Emerita analoga (Stimpson) (Crustacea, Hippidae) and Belcher’s gull Larus belcheri (Vigors) (Aves ...
