    • Cercariae of a Bird Schistosome Follow a Similar Emergence Pattern under Different Subarctic Conditions: First Experimental Study 

      Soldánová, Miroslava; Born-Torrijos, Ana; Kristoffersen, Roar; Knudsen, Rune; Amundsen, Per-Arne; Scholz, Tomas (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-06-03)
      The emergence of cercariae from infected mollusks is considered one of the most important adaptive strategies for maintaining the trematode life cycle. Short transmission opportunities of cercariae are often compensated by periodic daily rhythms in the cercarial release. However, there are virtually no data on the cercarial emergence of bird schistosomes from freshwater ecosystems in northern ...

    • Mining various genomic resources to resolve old alpha-taxonomy questions: A test of the species hypothesis of the Proteocephalus longicollis species complex (Cestoda: Platyhelminthes) from salmonid fishes 

      Brabec, Jan; Rochat, Eloïse Coralie; Knudsen, Rune; Scholz, Tomas; Costa, Isabel Blasco (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-01-24)
      High-throughput sequencing strategies became commonly employed to study non-model parasites, but the corresponding genomes and transcriptomes were seldom mined following the original publication. Similar to the data generated with genome skimming techniques based on shallow-depth shotgun gen omes, various genomic and transcriptomic resources can be screened for useful molecular phylogenetic markers ...

    • Molecular analyses reveal high cryptic diversity of trematodes in a sub-Arctic lake 

      Soldánová, Miroslava; Georgieva, Simona; Roháčová, Jana; Knudsen, Rune; Kuhn, Jesper A.; Henriksen, Eirik Haugstvedt; Siwertsson, Anna; Shaw, Jenny C.; Kuris, Armand M.; Amundsen, Per-Arne; Scholz, Tomas; Lafferty, Kevin D.; Kostadinova, Aneta (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-03-14)
      To identify trematode diversity and life-cycles in the sub-Arctic Lake Takvatn, Norway, we characterised 120 trematode isolates from mollusc first intermediate hosts, metacercariae from second intermediate host fishes and invertebrates, and adults from fish and invertebrate definitive hosts, using molecular techniques. Phylogenies based on nuclear and/or mtDNA revealed high species richness (24 ...

    • Somatic Dimorphism in Cercariae of a Bird Schistosome 

      Soldánová, Miroslava; Kundid, Petra; Scholz, Tomas; Kristoffersen, Roar; Knudsen, Rune (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-02-24)
      Phenotypic polymorphism is a commonly observed phenomenon in nature, but extremely rare in free-living stages of parasites. We describe a unique case of somatic polymorphism in conspecific cercariae of the bird schistosome Trichobilharzia sp. “peregra”, in which two morphs, conspicuously different in their size, were released from a single Radix balthica snail. A detailed morphometric analysis ...
