Observations on the distribution, specificity and pathogenicity of the acanthocephalan Pomphorhynchus laevis
Responses of Squalis cephalus intestinal mucous cells to Pomphorhynchus laevis
a few Pomphorhynchus laevis and Echinorhynchus truttae were found) or acanthella stages were discarded.
Parasite-induced alteration of plastic response to predation threat: increased refuge use but lower food intake in Gammarus pulex infected with the acanothoccphalan Pomphorhynchus laevis.
Influence of host nutritional condition on post-infection traits in the association between the manipulative acanthocephalan Pomphorhynchus laevis and the amphipod Gammarus pulex.
Comparison of the metal accumulation capacity between the Acanthocephalan pomphorhynchus laevis
and larval nematodes of the genus Eustrongylides sp.
Is metal accumulation in Pomphorhynchus laevis
dependent on parasite sex or infrapopulation size?
To get round this problem, Dr Jeffrey Karp and his team looked at a parasitic worm called Pomphorhynchus laevis
, which anchors itself to the slippery surface of the host's intestine using micro-needle tips that pierce the surface and then, once wet, swell to lock tight.
The population biology of the acanthocephalan Pomphorhynchus laevis
(Muller) in the river Avon.
Almost all cases (five out of six) for which an increase of predation risk of infected intermediate hosts was shown concern aquatic crustaceans with marked color effects of their acanthocephalan parasites: Gammarus lacustris infected by Polymorphus paradoxus (Holmes and Bethel 1972, Bethel and Holmes 1977) or by Polymorphus minutus (Hindsbo 1972); Hyalella azteca infected by Corynosoma constrictum (Bethel and Holmes 1977); Gammarus pulex infected by Pomphorhynchus laevis (Kennedy et al.
In our study, we used a different acanthocephalan system: Pomphorhynchus laevis, which uses Gammarus pulex as intermediate host.
