Unclear host taxonomy hinders parasite studies: An up‐to‐date checklist of the protozoan and metazoan parasites of Phoxinus minnows (Teleostei: Leuciscidae)

Journal of Fish Biology, Volume 105, Issue 6, Page 1501-1539, December 2024.
Abstract Phoxinus minnows are small freshwater fish found throughout Eurasia. The taxonomy of this genus is still under investigation, and new species are regularly described. They are frequently introduced outside their native range due to their use as live bait for angling, and such fish introductions can have diverse impacts on the recipient areas ...

Effect of Cothurnia variabilis and Epistylis gammari (Ciliophora: Peritrichia) on Metabolic Rate of the Crayfish Cambarellus (Cambarellus) montezumae

Diversity, 2021
Peritrichs usually settle on the external surface and gills of crustaceans. However, their physiological effect on the host has not been studied. Respiratory rate is a susceptible index for some factors that affect an organism.

Symbiotic species diversity can explain invasion success and host–parasite system stability: The case of gammarid hosts

Ecosphere, Volume 15, Issue 7, July 2024.
Abstract A major current challenge related to invasions is the absence of a comprehensive theoretical basis for preventing the introduction of alien species and controlling their populations. By using a macroecological framework, we aim to examine patterns of symbiotic species diversity across native and invasive hosts to understand the mechanisms ...

First record of epibionts peritrichids and suctorians (Protozoa, Ciliophora) on Pomacea lineata (Spix, 1827)

Brazilian Archives of Biology and Technology, 2006
This study made a survey on the ciliate protozoans from Peritrichid and Suctorian taxa, epibionts of Pomacea lineata (Spix, 1827) (Ampullariidae). Fifty mollusks were collected in places of irrigation ditches and shell was scraped with a scalpel and the ...

The effect of external flow on 3D orientation of a microscopic sessile suspension feeder, Vorticella convallaria

Annals of the New York Academy of Sciences, Volume 1537, Issue 1, Page 51-63, July 2024.
Vorticella are microscopic sessile suspension feeders that live attached to substrates in aquatic environments. They feed using a self‐generated feeding current. Their feeding rate depends on an individual's orientation relative to the substrate and ambient flow. We exposed individuals to varying flow speeds and recorded their 3D orientation.

Relationship between Water Quality Parameters and Parasite Infestation in Farmed Oreochromis niloticus in Selected Rift Valley Counties, Kenya

Aquaculture Research, Volume 2024, Issue 1, 2024.
Globally, parasitic infections hinder aquaculture productivity and sustainability. Improper water quality parameters reduce fish immunity, make them susceptible to parasites, and enhance parasitic proliferation in culture systems. Subsequently, this study aimed to determine the prevalence and intensity of ecto‐ and endo‐parasite infesting Oreochromis ...
