Housekeeping genes for quantitative expression studies in the three-spined stickleback Gasterosteus aculeatus [PDF]

open access: yes, 2008
Background During the last years the quantification of immune response under immunological challenges, e.g. parasitation, has been a major focus of research.

Multiple ecological scales of host-parasite interactions using the three-spined stickleback and Schistocephalus solidus model system [PDF]

open access: yes, 2017
Parasites are powerful forces of selection shaping evolutionary and ecological processes such as maintenance of genetic polymorphism, species diversity, divergent selection, or even the evolution of sex.

Innate versus adaptive immunity in sticklebacks: evidence for trade-offs from a selection experiment [PDF]

open access: yes, 2018
In vertebrates, the immune system consists of two arms of different characteristics: the innate and the acquired immune response. Parasites that are only shortly exposed to the immune system are most efficiently attacked by fast, constitutive innate ...

Purification and characterization of a saccharide-binding protein from penetration glands of Diplostomum pseudospathaceum – a bifunctional molecule with cysteine protease activity

open access: yesParasitology, 2003
A beta-1,3-glucan-binding lectin from the penetration glands of Diplostomum pseudospathaceum cercariae was isolated by affinity chromatography using yeast glucan and curdlan as affinity matrices. Further purification to homogeneity was performed by cation-exchange chromatography.

Identification tools of Diplostomum spathaceum Rudolphi, 1819 (Diplostomida: Diplostomidae), a trematode parasite of herring gull (Larus argentatus) [PDF]

open access: yes
Specimens of the genus Diplostomum von Nordmann, 1832 (Trematoda, Diplostomidae) were collected from the intestine of the herring gull, Larus argentatus (Laridae), from El-Manzala Lake (Port Said City, Egypt).

Genetically determined resistance and tolerance to Diplostomum sp. parasite in farmed rainbow trout [PDF]

open access: yes, 2020
Parasite infectivity, virulence and host resistance have been in the centre of the scientific interest when it comes to host-parasite relationships. In addition to resistance, hosts may also vary in their tolerance against parasites. This is important to

No evidence of local adaptation of immune responses to Gyrodactylus in three-spined stickleback (Gasterosteus aculeatus) [PDF]

open access: yes, 2016
Parasitism represents one of the most widespread lifestyles in the animal kingdom, with the potential to drive coevolutionary dynamics with their host population. Where hosts and parasites evolve together, we may find local adaptation. As one of the main

Ultrastructural changes in the digestive system during the metacercarial development in Diplostomum pseudospathaceum (Trematoda: Digenea: Diplostomidae)

open access: yesProceedings of the Zoological Institute RAS, 2013
Ultrastructural organization of the foregut and intestinal caeca was investigated in the developing and mature metacercariae of Diplostomum pseudospathaceum. The features of metamorphosis were found in the development of the metacercarial caeca and oral sucker.

Biology and ecology of trematodes parasitizing aquatic snails in the Ruhr reservoir system in Germany [PDF]

open access: yes, 2016
Parasites are integral and important elements of ecosystems that occur in virtually every habitat on this planet (Poulin 1999, Hudson et al. 2006). However, except for the obviously important role of some species as disease agents, parasites have long ...

Diversity, Phylogenetics And Life Cycles Of Diplostomoidean (Digenea: Diplostomoidea) Of The Upper Midwest [PDF]

open access: yes, 2023
The superfamily Diplostomoidea Poirier, 1886 consists of a diverse, globally distributed group ofparasitic flatworms parasitic as adults in reptiles, birds, mammals, and very rarely, fish.
