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

open access: yesJ Fish Biol
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 ...

Proposal of Tiddergasilus gen. nov. (Ergasilidae: Cyclopoida) for T. iheringi comb. nov. from the gills of Hoplias malabaricus (Erythrinidae: Characiformes) from Brazil

open access: yesZoologia (Curitiba), 2018
Ergasilus von Nordmann, 1832 is the type and the most speciose genus of Ergasilidae, with more than 150 valid species. The first species of this genus, Ergasilus iheringi Tidd, 1942, was described from the Neotropical Region, from the gills of Hoplias ...

Ergasilus siboldi of Balkhash lake

open access: yesBULLETIN OF THE L.N. GUMILYOV EURASIAN NATIONAL UNIVERSITY. BIOSCIENCE SERIES, 2019
In the middle of the last century, in order to make rational use of the biological productivity of Inland water bodies in the USSR, full-scale ichthyintroduction works were carried out. In this regard, a complex reconstruction of the ichthyofauna was carried out of the Ile-Balkhash basin.

Characterization of the complete mitochondrial genome of Ergasilus anchoratus and phylogeny of Copepoda

open access: yes, 2023
Abstract The mitochondrial (mt) genome can provide data for phylogenetic analyses and evolutionary biology. Herein, we sequenced and annotated the complete mt genome of Ergasilus anchoratus. This mt genome was 13852 bp long and comprised 13 protein-coding genes (PCGs), 22 tRNAs and 2 rRNAs.

Relationship between seasonal dynamics in zooplankton density and Ergasilus infection in two reservoirs [PDF]

open access: yesActa Veterinaria Brno, 2018
Ergasilosis is a common parasitic disease of fish caused by species of the family Ergasilidae. During the fish growing season, parasitic abundance (including developmental stages) changes in relation to zooplankton development. In this study, we evaluated the seasonal dynamics of ergasilosis in relation to zooplankton development ...

A comparison of the use of different swab materials for optimal diagnosis of amoebic gill disease (AGD) in Atlantic salmon (Salmo salar L.)

open access: yesJournal of Fish Diseases, Volume 43, Issue 11, Page 1463-1472, November 2020., 2020
Abstract Routine gill swabbing is a non‐destructive sampling method used for the downstream qPCR detection and quantitation of the pathogen Neoparamoeba perurans, a causative agent of amoebic gill disease (AGD). Three commercially available swabs were compared aiming their application for timelier AGD diagnosis (Calgiswab® (calcium alginate fibre ...

Os crustáceos parasitos de peixes da Amazônia Brasileira. II - Ergasilus leporinidis n. sp. (Copepoda: Cyclopoidea) das branquias de Leporinus fasciatus (Bloch) [PDF]

open access: yesActa Amazonica, 1981
Resumo Ergasilus leporimdis n. sp. é descrita de um peixe amazônico chamado aracu (Anostomidae: Leporinus fasciatus (Bloch). A nova espécie é semelhante à E. bryconis Thatcher, 1981, mas carece da seta pectinada no terceiro segmento do primeiro exopódito.

Temporally consistent species differences in parasite infection but no evidence for rapid parasite‐mediated speciation in Lake Victoria cichlid fish

open access: yesJournal of Evolutionary Biology, Volume 33, Issue 5, Page 556-575, May 2020., 2020
Species composition of Cichlidogyrus infection was similar among the closely related cichlid species of the Lake Victoria radiation (in orange), but differed between this lineage and two distantly related species (belonging to nonradiating sister lineages, in blue).
