The Role of Host Age at Exposure, Host–Parasite Genetics and Host Size‐Parasite Length Mechanics in Shaping the Outcome of Parasitic Infections in Three Zooplankton Taxa

open access: yesFreshwater Biology, Volume 70, Issue 8, August 2025.
ABSTRACT Understanding disease emergence and spread is a key challenge of evolutionary ecology, and there is growing evidence that host age at exposure is pivotal for improving our understanding. Previous studies of the Daphnia‐Pasteuria system found that younger hosts were more susceptible and produced more transmission stages than older ones, with ...

Characterisation of a large family of polymorphic collagen-like proteins in the endospore-forming bacterium Pasteuria ramosa

open access: yes, 2011
Collagen-like proteins containing glycine-X-Y repeats have been identified in several pathogenic bacteria potentially involved in virulence. Recently, a collagen-like surface protein, Pcl1a, was identified in Pasteuria ramosa, a spore-forming parasite of

The polypeptide components of the parasporal fibres of Pasteuria penetrans

open access: yes, 2002
A variety of treatments were tested for their ability to solubilize the parasporal fibres from Pasteuria penetrans, a parasite of some plant-parasitic nematodes.

Studying the genetic basis of ecological interactions with intergenomic epistasis

open access: yesOikos, Volume 2025, Issue 6, June 2025.
In a community, the phenotype or fitness of genotypes of a focal species can depend on the genotypes of other species. Such between‐species genetic interactions are increasingly referred to as intergenomic epistasis, analogous to the classical definition of (intragenomic) epistasis in genetics.

Acclimation temperature and parasite infection drive metabolic changes in a freshwater fish at different biological scales

open access: yesFunctional Ecology, Volume 39, Issue 2, Page 350-361, February 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Environmental stressors such as elevated temperature and parasite infection can impact individual energy metabolism. However, organismal responses to co‐occurring stressors and their effects across biological scales remain unexplored despite the importance of ...

Variable-Number-of-Tandem-Repeats Analysis of Genetic Diversity in Pasteuria ramosa [PDF]

open access: yes, 2018
Variable-number-of-tandem-repeats (VNTR) markers are increasingly being used in population genetic studies of bacteria. They were recently developed for Pasteuria ramosa, an endobacterium that infects Daphnia species. In the present study, we genotyped P.

Parasite transmission stage abundance varies in lakes over time and space

open access: yesLimnology and Oceanography, Volume 69, Issue 9, Page 2167-2179, September 2024.
Abstract Environmentally transmitted parasites produce transmission stages that can remain viable and infective for extended periods of time in the environment where susceptible hosts may encounter them. Although many parasites have this mode of transmission, the abundance and distribution of environmental transmission stages have largely been ...

Data from: Parasitism drives host genome evolution: insights from the Pasteuria ramosa - Daphnia magna system

open access: yes, 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 ...

Interactions between microsporidia and other members of the microbiome

open access: yesJournal of Eukaryotic Microbiology, Volume 71, Issue 5, September/October 2024.
Abstract The microbiome is the collection of microbes that are associated with a host. Microsporidia are intracellular eukaryotic parasites that can infect most types of animals. In the last decade, there has been much progress to define the relationship between microsporidia and the microbiome.
