Challenging Host Specificity: Malacosporean Parasite Dynamics—Tetracapsuloides bryosalmonae Beyond Salmonids—An Infection Experiment

Journal of Fish Diseases, EarlyView.
ABSTRACT Proliferative Kidney Disease (PKD) is a severe parasitic disease of salmonids caused by the malacosporean endoparasite Tetracapsuloides bryosalmonae. In the fish intermediate host, the parasite is disseminated via the circulatory system and ultimately reaches the kidney, where it matures before releasing infective spores into the environment ...

Simultaneous quantification of rDNA methylation and copy number: Constraints to natural variation in humans and cell lines.

PLoS ONE
Ribosomal DNA (rDNA) copy number (CN) varies widely both across and within species. In humans, it has been hypothesized that rDNA transcriptional activity is partially regulated by rDNA methylation status.

Histopathological and Molecular Data on Myxobolus spp. Infecting Bryconid Fish From the Brazilian Pantanal Wetland

Journal of Fish Diseases, EarlyView.
ABSTRACT Previous studies described Myxobolus umidus infecting the spleen of Brycon hilarii, whereas Myxobolus pantanalis and Myxobolus salminus infecting the gill filaments of Salminus brasiliensis. In this study, we provided supplementary morphological and molecular data on these three Myxobolus species and histopathological analyses of the tissues ...

Diagnosis and Off‐Label Treatment of Subcutaneous Putative Dracunculoid Nematodes in Apteronotus albifrons Originating From Wild‐Caught Fisheries

Journal of Fish Diseases, EarlyView.
ABSTRACT Apteronotus albifrons (Gymnotiformes: Apteronotidae), commonly known as the black ghost knifefish, is a high‐value ornamental fish that is susceptible to various parasites. The affected fish were wild‐caught fisheries and subsequently introduced into a commercial breeding system.

Nodular Lesions in the Pyloric Caeca of Sardinella aurita (Teleostei) Associated With the Cestode Anthobothrium sp. 1 Larvae (Platyhelminthes: Eucestoda) Off Tunisia, Mediterranean Sea

Journal of Fish Diseases, EarlyView.
ABSTRACT Examination of round sardinella Sardinella aurita Valenciennes, 1847 (Clupeidae) from the Gulf of Tunis (Tunisia) revealed the first local and Mediterranean record of Anthobothrium sp. 1 sensu Jensen & Bullard, 2010 (Tetraphyllidea incertae sedis, Anthobothrium).

Comprehensive revision of Mallomonas sect. Peroneides stat. nov. (Chrysophyceae) integrating morphology and multigene phylogeny

Journal of Phycology, EarlyView.
Abstract Mallomonas is among the most diverse genera of Chrysophyceae, yet many of its lineages remain taxonomically unresolved due to limited molecular sampling. Mallomonas series Peronoides, historically limited to four species, has posed persistent taxonomic difficulties, most notably the long‐standing and problematic reliance on a rare ...

Bridging the gap between genomic, phenotypic, and modeling data in picophytoplankton–virus interactions

Journal of Phycology, EarlyView.
Abstract We present a comprehensive synthesis of recent developments in methodological approaches to combine experimental and genomic studies of picophytoplankton–virus interactions. This synthesis will not only enhance our understanding of these relationships but also stimulate new hypotheses for the interpretation of metagenomic data and enrich ...

Crawling under the radar: Two novel Paulinella species expand knowledge about the ecology and evolution of a primary plastid‐containing amoeba lineage

Journal of Phycology, EarlyView.
Abstract The genus Paulinella represents a rare, independent case of primary endosymbiosis, providing a unique system to study the early stages of organelle evolution. Here, we expand current understanding of primary plastid endosymbiosis through the discovery and characterization of two novel photosynthetic amoebae, Paulinella marae sp. nov.

Lithochloron, a new genus of green algae residing in coral skeleton (Cladophorales, Chlorophyta)

Journal of Phycology, EarlyView.
Abstract Coral skeletons host diverse microbial communities, including endolithic green algae that contribute to holobiont functioning. The siphonous green alga Ostreobium (Bryopsidales) is arguably the best‐known coral endolith, but recent environmental sequencing has indicated that other lineages of green algae may also inhabit the coral skeleton ...
