Dietary supply with polyunsaturated fatty acids and resulting maternal effects influence host -- parasite interactions [PDF]

open access: yes, 2013
Interactions between hosts and parasites can be substantially modulated by host nutrition. Polyunsaturated fatty acids (PUFAs) are essential dietary nutrients; they are indispensable as structural components of cell membranes and as precursors for ...

Evolutionary and proximate mechanisms shaping host-parasite interactions : the case of "Daphnia magna" and its natural bacterial parasite "Pasteuria ramosa" [PDF]

open access: yes, 2011
Host-parasite interactions are composed of a sequence of steps, all necessary for successful infection: parasites need to encounter their hosts, to enter into their bodies, and to proliferate within them. Selection will act on the mechanisms used in each

Evolution of spatially structured host–parasite interactions [PDF]

open access: yesJournal of Evolutionary Biology, 2015
AbstractSpatial structure has dramatic effects on the demography and the evolution of species. A large variety of theoretical models have attempted to understand how local dispersal may shape the coevolution of interacting species such as host–parasite interactions.

Resolving the infection process reveals striking differences in the contribution of environment, genetics and phylogeny to host-parasite interactions [PDF]

open access: yes, 2011
Background Infection processes consist of a sequence of steps, each critical for the interaction between host and parasite. Studies of host-parasite interactions rarely take into account the fact that different steps might be influenced by different ...

Isothermal diagnostic assays for the detection of soil-transmitted helminths based on the SmartAmp2 method

open access: yesParasites & Vectors, 2017
Background Diagnosis of soil-transmitted helminths (STHs) has traditionally relied on stool microscopy, which has a number of critical deficiencies. Molecular diagnostics are powerful tools to identify closely related species, but the requirement for ...

Differential expression of immune defences is associated with specific host-parasite interactions in insects [PDF]

open access: yes, 2009
Recent ecological studies in invertebrates show that the outcome of an infection is dependent on the specific pairing of host and parasite. Such specificity contrasts the long-held view that invertebrate innate immunity depends on a broadspectrum ...

HIF-1α hampers dendritic cell function and Th1 generation during chronic visceral leishmaniasis

open access: yesScientific Reports, 2018
Inflammation, although responsible for controlling infection, is often associated with the pathogenesis of chronic diseases. Leishmania donovani, the causative agent of visceral leishmaniasis, induces a strong inflammatory response that leads to ...

Exploring the virulence gene interactome with CRISPR/dCas9 in the human malaria parasite

open access: yesMolecular Systems Biology, 2020
Mutually exclusive expression of the var multigene family is key to immune evasion and pathogenesis in Plasmodium falciparum, but few factors have been shown to play a direct role.

Host specificity and genetics of host resistance in the "Daphnia-Pasteuria" host-parasite system [PDF]

open access: yes, 2012
Antagonistic coevolution plays an important role in a large number of evolutionary and ecological phenomena. Furthermore, according to the Red Queen Theory coevolution between hosts and their parasites may explain the maintenance of sexual reproduction ...

Ecological factors affect host-parasite coevolution [PDF]

open access: yes, 2021
Host-parasite interactions often fuel coevolutionary change. However, parasitism is one of a myriad of possible ecological interactions in nature. Biotic (e.g., predation) and abiotic (e.g., temperature) variation can amplify or dilute parasitism as a ...
