A Population Biology Perspective on the Stepwise Infection Process of the Bacterial Pathogen Pasteuria ramosa in Daphnia

, 2016
The infection process of many diseases can be divided into series of steps, each one required to successfully complete the parasite's life and transmission cycle.

Identification of new single nucleotide polymorphism-based markers for inter- and intraspecies discrimination of obligate bacterial parasites (Pasteuria spp.) of invertebrates

, 2011
Protein-encoding and 16S rRNA genes of Pasteuria penetrans populations from a wide range of geographic locations were examined.

The cuticle proteome of a planktonic crustacean

PROTEOMICS, Volume 24, Issue 14, July 2024.
Abstract The cuticles of arthropods provide an interface between the organism and its environment. Thus, the cuticle's structure influences how the organism responds to and interacts with its surroundings. Here, we used label‐free quantification proteomics to provide a proteome of the moulted cuticle of the aquatic crustacean Daphnia magna, which has ...

Acclimation to warmer temperatures can protect host populations from both further heat stress and the potential invasion of pathogens

Global Change Biology, Volume 30, Issue 6, June 2024.
How hosts and pathogens react to higher temperatures depends on both their heat tolerance and capacity for population growth. Our study found that hosts overall fare better in warmer conditions, with faster growth rates and a greater capacity to tolerate the heat.

The hidden costs of resistance: Contrasting the energetics of successfully and unsuccessfully fighting infection

Functional Ecology, Volume 38, Issue 4, Page 714-723, April 2024.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Exposure to a pathogen is predicted to lead to increased energy use as hosts attempt to activate a costly immune system and repair damaged tissue. To meet this demand, metabolic rates, which capture the rate at which a host can use, transform and expend energy, are ...

Interactions between environmental stressors: the influence of salinity on host-parasite interactions between Daphnia magna and Pasteuria ramosa

, 2013
Interactions between environmental stressors play an important role in shaping the health of an organism. This is particularly true in terms of the prevalence and severity of infectious disease, as stressors in combination will not always act to simply ...

Evidence for diversifying selection of genetic regions of encoding putative collagen-like host-adhesive fibers in Pasteuria penetrans [PDF]

, 2019
Pasteuria spp. belong to a group of genetically diverse endospore-forming bacteria (phylum: Firmicutes) that are known to parasitize plant-parasitic nematodes and water fleas (Daphnia spp.).

Parasitism drives host genome evolution: Insights from thePasteuria ramosa-Daphnia magnasystem

, 2017
Because parasitism is thought to play a major role in shaping host genomes, it has been predicted that genomic regions associated with resistance to parasites should stand out in genome scans, revealing signals of selection above the genomic background ...

Understanding the interaction between an obligate hyperparasitic bacterium, Pasteuria penetrans and its obligate plant-parasitic nematode host, Meloidogyne spp.

, 2009
Pasteuria penetrans is an endospore-forming bacterium, which is a hyperparasite of root-knot nematodes Meloidogyne spp. that are economically important pests of a wide range of crops.

An alternative route of bacterial infection associated with a novel resistance locus in the Daphnia-Pasteuria host-parasite system

, 2020
To understand the mechanisms of antagonistic coevolution, it is crucial to identify the genetics of parasite resistance. In the Daphnia magna-Pasteuria ramosa host-parasite system, the most important step of the infection process is the one in which P ...
