Parasite Biology and Host Interactions

The paper shows that multiple parasites with complex life cycles can stabilize predator-prey systems through manipulation and reproduction parameters, challenging previous theoretical assumptions.

The paper evaluates how parasite contamination affects estimates of mitochondrial enzyme activities in infected fish livers and finds that enzyme activity estimates remain accurate even with contamination.

The paper models how parasite doses interact with host defense tiers, finding that intermediate doses prolong infections by partially overcoming defenses without triggering strong adaptive responses.

This study examines how lungworm infection affects miRNA and mRNA expression in cane toads, finding upregulated miRNAs linked to immune response pathways and minimal mRNA changes.

The paper describes a new parasitic ciliate, Metacollinia emscheri, found in freshwater amphipods and confirms its placement in the Collinidae family through phylogenetic analysis.

This study updates the distribution of Ergasilus kandti and investigates the phylogenetic relationships of African ergasilids using mitochondrial genomes and microscopy.

The paper shows that coinfection with two pathogens reduces host survival but limits the spread of the more virulent pathogen, suggesting potential population-level benefits.

This study examines transcriptional differentiation of a parasite across its host's metamorphosis, finding greater transcriptional divergence in the parasite than its host.

This paper demonstrates the use of energy dispersive spectroscopy to measure the stoichiometry of individual microbial parasites within host infrapopulations, revealing differences in nutrient composition and their impact on host fecundity.

The paper uses eDNA and niche modeling to show that environmental stressors, not just parasite abundance, drive disease emergence in wild salmonids.

This paper investigates the impact of Ordospora pajunii on Daphnia hosts, finding low virulence and context-dependent effects, and identifies it as a valuable model for studying mutualism-parasitism shifts.

The paper examines how within-host parasite interactions affect between-host transmission dynamics, finding localized effects for some species but not others.

This paper examines the ultrastructure of the tegument in mature mother sporocysts of Bunocotyle progenetica, revealing its complex structure and functional roles in nutrient absorption and cell renewal.

This study shows that the mosquito parasite Lambornella clarki is locally adapted to its host but not temperature, with higher infection rates on sympatric host populations.

The paper distinguishes cophylogenetic signal from phylogenetic congruence using simulations, showing that global-fit methods detect signal without congruence, while event-based methods indicate stronger evolutionary dependency.

This study presents the first genome assembly of Ligula intestinalis and identifies differentially expressed genes between adult worms and plerocercoid larvae, revealing genes related to reproductive development and immune evasion.

This paper describes an RFID tagging method for salmon lice and evaluates glue effectiveness, finding high tag retention with some batch variability.

The paper examines how temperature and intraspecific variation affect host-parasite interactions in aquatic ecosystems using a mosquito and its parasite model system.

This study examines how the helminth Pomphorhynchus laevis manipulates antipredator behaviors in its intermediate host Gammarus pulex, showing a switch in refuge use behavior but not activity rate during parasite development.

This study shows that fibrosis immune response in stickleback fish improves locomotor performance despite increased body stiffness, revealing unexpected fitness consequences of immune responses.

The study tests if S. solidus infection facilitates other parasite infections in stickleback, finding higher parasite richness in infected individuals.

This study examines how environmental and host traits influence the ectoparasite community of Akodon azarae, finding that minimum temperature has the strongest impact.

This study examines macroparasite diversity in cavefish Astyanax mexicanus and finds higher parasite richness in caves compared to surface fish, suggesting ecological and evolutionary factors shaping host-parasite interactions.

The paper identifies proteins secreted by Schistocephalus solidus that may manipulate its host, with some proteins being species-specific.

The paper investigates the molecular and evolutionary basis of Anisakis pegreffii's ability to infect different hosts by comparing transcriptomic profiles of larvae in rats and fish.

This study uses DNA profiling to show that Neobenedenia girellae is a distinct species from N. melleni, with many previous identifications likely incorrect.

The paper provides annotated transcriptomes of Microphallus trematodes from two New Zealand snail species and identifies candidate genes related to parasitism and salinity stress.

This study examines transcriptomic changes in Schistocephalus solidus during development in different hosts, identifying reprogramming events linked to infectivity and reproduction.
