Does bigger mean sicker? A systematic review and meta‐analysis of the intraspecific relationship between host body size and parasite infection across vertebrate taxa

Oikos, Volume 2026, Issue 10, October 2026.
Elucidating the determinants of parasite infection levels of individuals within a population is a basic but important step for understanding the roles of parasites in natural systems. Among intraspecific studies on vertebrate hosts and metazoan parasites, host body size (length/mass) is probably the most frequently reported factor determining parasite ...

Do Parasite Effects on Fish Body Condition Depend on Host Size and External Temperature? A Meta‐Analytic Approach

Journal of Zoology, Volume 330, Issue 1, Page 32-40, September 2026.
Evaluating relationships between host body condition indices (BCIs) and parasite infections is a common approach for assessing the negative effects of parasites on host health. Researchers generally expect negative correlations between BCIs and infection levels; however, empirical results are often highly variable among host–parasite systems.

Syndromic Convergence in Aquaculture Disease Management: A Critical Review of Climate‐Pathobiome Interactions, Diagnostic Frameworks, and Knowledge Gaps

Reviews in Aquaculture, Volume 18, Issue 4, September 2026.
Syndromic convergence (SyCo) reframes aquaculture disease as the synergistic product of climate‐driven stressors, pathobiome communities, and host immune compromise, not single pathogens. A five‐criterion scoring matrix, composite early warning index, and three‐layer intervention framework together operationalize this shift toward predictive ...

Progress and Challenges in Phylogenomics and Genomics of Lophotrochozoa/Spiralia

Zoologica Scripta, Volume 55, Issue 4, Page 521-544, July 2026.
ABSTRACT Lophotrochozoa is one of the three major bilaterian groups comprising more than half of the bilaterian phyla. Lophotrochozoa includes among others Mollusca, Annelida, Platyhelminthes and Rotifera. Despite representing such a large proportion of animal diversity, they are historically understudied and genomic resources have been scarce. However,

Come rain or come shine: environmental effects on the infective stages of Sparicotyle chrysophrii, a key pathogen in Mediterranean aquaculture

Parasites & Vectors, 2018
Background Evidence concerning the environmental influence on monogenean transmission and infection processes is widely accepted, although only the effects of a limited number of abiotic factors on particular monogenean species have been explored.

Efficacy of a therapeutic bath with selected antiparasitic drugs on a Dactylogyrus anchoratus infection in juvenile common carp (Cyprinus carpio)

Veterinární Medicína, 2023
The study aimed to assess the effects of a therapeutic bath of five different antiparasitic drugs, in different baths and durations: fenbendazole (25 mg l-1, 12 h and 2 × 12 h), formaldehyde (0.17 ml l-1, 15 min), ivermectin (0.031 mg l-1, 1 h ...

Can manipulative parasites modify host‐mediated trophic effects? Experimental evidence from Schistocephalus solidus and three‐spined sticklebacks

Functional Ecology, Volume 40, Issue 6, Page 1603-1618, June 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Parasites can alter host traits, thereby reshaping host interactions and modifying density‐ and trait‐mediated effects in trophic cascades. But despite increasing research in parasite ecology, the cascading effects of parasitism from individual hosts to population and ...

Fish health, environmental contaminants, and disease management in Ghanaian aquaculture: A systematic review

Journal of the World Aquaculture Society, Volume 57, Issue 3, June 2026.
Abstract Fish health significantly influences aquaculture productivity, sustainability, food security, and public health. Despite Ghana's rapid aquaculture expansion, the sector remains constrained by widespread disease outbreaks and environmental threats. This systematic review synthesizes existing literature (2010–2024) to comprehensively assess fish

An automated 3D modeling pipeline for constructing 3D models of MONOGENEAN HARDPART using machine learning techniques

BMC Bioinformatics, 2019
Background Studying structural and functional morphology of small organisms such as monogenean, is difficult due to the lack of visualization in three dimensions.
