Disease‐associated mortality drives reduction in Yukon River Chinook salmon escapement: A novel method for quantifying the negative impacts of ‘misfit’ parasites to improve fisheries management

open access: yesJournal of Applied Ecology, Volume 63, Issue 6, June 2026.
Alaska Department of Fish and Game is implementing an annual monitoring program at the mouth of the Yukon River where our model will estimate the proportion of Chinook salmon at risk from parasite‐induced mortality to inform annual management. Moreover, the model is broadly applicable to other fungal‐like and myxozoan parasites of conservation concern,

Life cycle studies of Myxobolus parviformis sp. n. (Myxozoa: Myxobolidae) from bream [PDF]

open access: yesDiseases of Aquatic Organisms, 2005
We experimentally followed the life cycle of Myxobolus parviformis sp. n., a myxozoan parasite from the gills of common bream Abramis brama L. Establishing the development of both stages (myxospore and actinospore) in 2 consecutive, full transmission trials, we were able to separate plasmodia of a common genotype from sympatric Myxobolus spp. occurring

Waterbirds and Other Drivers of Endoparasite Communities Across a Hierarchy of Spatial Scales

open access: yesFreshwater Biology, Volume 71, Issue 4, April 2026.
ABSTRACT Understanding drivers of parasite community structure is compromised by poor sampling and historical focus on one host‐one parasite systems. Yet parasites are ubiquitous and co‐infections are common. This study aimed to identify how various drivers, ranging from landscape scale (waterbird movements, hydrological connectivity, region, host ...

Myxobolus sp. and Henneguya sp. (Cnidaria: Myxobolidae) natural co-infection in the kidney of Piaractus mesopotamicus (Characiformes: Serrasalmidae) [PDF]

open access: yesParasitology Research, 2017
This study evaluated the myxozoan infection and histopathology of the kidney of freshwater fish Piaractus mesopotamicus from intensive fish farming in Brazil. A total of 55 fish were examined for myxozoan infection. Infected organs were processed by usual histology and stained with hematoxylin-eosin (H&E) and Ziehl-Neelsen (ZN).

Global Warming Affects the Pathogenesis of Important Fish Diseases in European Aquaculture

open access: yesReviews in Aquaculture, Volume 18, Issue 1, January 2026.
The effect of global warming on pathogens and their fish hosts that could exacerbate the negative outcomes for aquaculture. Changes in farming practices and the development of innovative mitigation tools may prove essential to cope with the effects and impacts of rising water temperatures on fish diseases in Europe.

Skin disease of Mugil cephalus due to Myxobolus sp. (Myxozoa: Myxobolidae.

open access: yesFish Pathology, 1989
最近日本沿岸各地で体表の多くの鱗上に腫物が形成された醜悪な外観となったボラがしばしば観察されている。腫物は粘液胞子虫のシスト集塊が鱗の露出部上に形成されたもので, その寄生体は胞子の形態からMyxobolus属に分類された。症状と病原体の特徴が殆ど同じ疾病がイスラエルのボラでも知られており, 本病は近年の日本沿岸のボラのごく普通の疾病であるが, 同時に世界的に分布するかもしれない。
