Myxobolus franciscoi sp. nov. (Myxozoa: Myxosporea: Myxobolidae), a parasite of Prochilodus argenteus (Actinopterygii: Prochilodontidae) from the Upper São Francisco River, Brazil, with a revision of Myxobolus spp. from South America

Zoologia (Curitiba), 2010
Myxobolus franciscoi sp. nov. (Myxozoa: Myxosporea: Myxobolidae) is described from the "curimatá-pacú" fish, Prochilodus argenteus Spix & Agassiz, 1829 (Actinopterygii: Prochilodontidae) from the Upper São Francisco River, Brazil.

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

Journal 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,

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

Freshwater 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 ...

Early warning signal for river‐borne diseases with almost no data

Methods in Ecology and Evolution, Volume 17, Issue 2, Page 615-625, February 2026.
Abstract Effective management of emerging river‐borne diseases requires early prediction of pathogen spatial distributions. However, data on pathogen locations are notoriously rare in the beginning of disease outbreaks and insufficient to feed existing predictive models.

Spleen as an Alternative Tissue for Estimating Tetracapsuloides bryosalmonae Load, Prevalence and Its Relationship With Proliferative Kidney Disease in Brown Trout

Journal of Fish Diseases, Volume 49, Issue 1, January 2026.
ABSTRACT Accurate pathogen detection is essential in fish health management and disease prevention. Pathogens often target different host tissues, and monitoring alternative target organs can provide important insights into disease progression. We evaluated the spleen as an alternative to the kidney for estimating the load and prevalence of the ...

Myxobolus sp., Another Opportunistic Parasite in Immunosuppressed Patients? [PDF]

Journal of Clinical Microbiology, 2001
ABSTRACT During a study of intestinal parasitic infections in human immunodeficiency virus-positive patients, a parasite belonging to the phylum Myxozoa , recently described from human samples, was identified in one sample.

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

Reviews 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.

Myxobolus infection in the cornea of the roach (Rutilus rutilus) in Lake Balaton [PDF]

Acta Veterinaria Hungarica, 2018
Infection of the cornea in fishes by Myxobolus plasmodia is a common but still little known site preference of myxosporeans. A sporadic but striking infection in the cornea of the roach (Rutilus rutilus) was observed in Lake Balaton, Hungary. Relatively small, round plasmodia 250 to 500 μm in diameter developed in the dense connective tissue of the ...

First report of Myxobolus (Cnidaria: Myxozoa) spores in human feces in Brazil [PDF]

Acta Amazonica, 2019
Most species of Myxobolus (Cnidaria: Myxozoa) infect freshwater and marine fish, and cause sporozoosis. Passage of myxozoan parasites into human feces has been described occasionally.
