open access: yes, 1998
We have learned a great deal in recent years about reading Horace\u27s satires; there is now widespread agreement that the speaker of the satires is himself a character within them, a persona.

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).

First study on parasites of Hemibrycon surinamensis (Characidae), a host from the eastern Amazon region. [PDF]

open access: yes, 2019
This study was the first investigation of communities and infracommunities of parasites of Hemibrycon surinamensis. All the fish collected in a tributary of the Amazon river were parasitized by one or more parasite species. The Brillouin diversity index (

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.

Consistent patterns of trophic niche specialisation in host populations infected with a non-native copepod parasite. [PDF]

open access: yes, 2017
Populations of generalist species often comprise of smaller sub-sets of relatively specialised individuals whose niches comprise small sub-sets of the overall population niche.
