This study examines gastrointestinal parasites in two sloth species from Costa Rica, finding no significant difference in parasite richness between species or habitats but highlighting habitat-specific diversity and host-specific parasite composition.

Geography is a stronger predictor of diversification of monogenean parasites (Platyhelminthes) than host relatedness in characid fishes of Middle America

This study finds that geography, not host relatedness, drives diversification of monogenean parasites in characid fishes, indicating host-switching is mediated by spatial proximity.

Symbiont virulence is a poor predictor of impacts on host population dynamics

The paper tests how symbiont virulence affects host population dynamics, finding that individual-level effects do not reliably predict population-level impacts.

The paper quantifies aggregation patterns of the fungal pathogen Bd in amphibians, showing higher aggregation than macroparasites and linking it to biological processes.

Resource Quality Differentially Impacts Daphnia Interactions with Two Parasites

This study shows resource quality differentially affects Daphnia interactions with two parasites, influencing infection and proliferation processes but not immune responses.

Evaluation of parasitic contamination and effects on estimates of mitochondrial enzymatic activities in infected fish livers

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.

Infection by the lungworm Rhabdias pseudosphaerocephala affects the expression of immune-related microRNAs by its co-evolved host, the cane toad Rhinella marina.

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.

Metacollinia emscheri n. sp., a novel sanguicolous apostome ciliate of freshwater amphipods (Gammarus spp.)

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

Unique cuticular morphology of a truly marine insect, Echinophthirius horridus von Olfers, 1816 (Phthiraptera: Echinophthiriidae)

This study describes the cuticular morphology of Echinophthirius horridus using microscopy techniques and discusses its adaptation to a marine lifestyle.

Extensive transcriptional differentiation and specialization of a parasite across its host's metamorphosis

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

Destabilized host-parasite dynamics in newly founded populations

The paper experimentally studies host-parasite dynamics in newly founded stickleback populations, finding destabilized infection rates and rapid eco-evolutionary responses.

When does a parasite become a disease? eDNA unravels complex host-pathogen dynamics across environmental stress gradients in wild salmonid populations

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

Highly resolved genome assembly and comparative transcriptome profiling reveal genes related to developmental stages of the tapeworm Ligula intestinalis

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.

First in family Rhabdiasidae: the reference-guided genome assembly of an invasive parasite, the cane toad lungworm (Rhabdias pseudosphaerocephala)

This paper assembles the first reference genome for Rhabdias pseudosphaerocephala and uses it to investigate genetic diversity and evolutionary placement within the Rhabdiasidae family.

Exploring Differential Gene Expression Profiles Of Dero (Allodero) Hylae In Their Parasitic And Free-Living Forms

This study compares gene expression profiles of Dero hylae in its parasitic and free-living forms to identify genes associated with morphological changes during lifestyle transition.

Applying taxonomic boundaries for species identification (ABIapp): A convenient and accurate application for species delimitation of parasitic helminths

The paper introduces ABIapp, a tool for helminth species delimitation using genetic distances, achieving 79% in silico and 75% empirical classification accuracy.

The parasite Schistocephalus solidus secretes proteins with putative host manipulation functions

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

Good host - bad host: molecular and evolutionary basis for survival, its failure, and virulence factors of the zoonotic nematode Anisakis pegreffii

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.

Genetic Monitoring and Molecular Phylogeny for Cymothoid Isopod Invasion in Egyptian Lake Qarun Fishes by Using adopted taxonomic marker (COI)

The paper uses COI gene sequencing to identify and track invasive Cymothoidae isopods in Lake Qarun, Egypt, linking their spread to environmental factors and ballast water transport.
