Given the pivotal role played by gut microbiota in regulating host immune system, great interest has arisen possibility of controlling fish health modulating microbiota. Hence, there is a need to better understand host-microbiota interactions after disease responses optimize use probiotics strengthen resilience and recovery.We tested effects probiotic feed additive rainbow trout challenged with causative agent for enteric red mouth disease, Yersinia ruckeri. We evaluated survival, gene...
Abstract Infections with the parasitic flagellate I chthyobodo necator (Henneguy, 1883) cause severe skin and gill disease in rainbow trout O ncorhynchus mykiss (Walbaum, 1792) juveniles. The epidermal disturbances including hyperplasia mucous cell exhaustion caused by parasitization are known, but no details on specific cellular humoral reactions have been presented. By applying gene expression methods immunohistochemical techniques, further of immune processes affected can be A population...
Grey seals (Halichoerus gryphus), the main final host of gastric parasitic nematode Contracaecum osculatum in Baltic, have recently recolonized southwestern Baltic Sea. This colonization could lead to an increase prevalence and intensity third-stage larvae C. livers cod (Gadus morhua), which serve as transport for this helminth. We performed a parasitologic study spring 2012 compared results with previously unpublished data from 1982/1983. Additionally, grey were counted annually 2000 2011...
Abstract Populations of grey seals ( Halichoerus grypus ), sprats Sprattus sprattus ) and cod Gadus morhua in the Baltic Sea are relatively stationary. The present work, applying classical molecular helminthological techniques, documents that also share a common parasite, anisakid nematode Contracaecum osculatum , which uses as final host fish transport hosts. Sequencing mitochondrial genes COX1 COX2 adult worms from third-stage larvae livers (sprats cod), showed all gene variants occur both...
We here describe the location of anisakid third stage larvae in Atlantic herring Clupea harengus L. caught North Sea August 2023. further demonstrate how industrial processing (mechanical gutting, removal entrails, head, tail, hypaxial anterior musculature and vertebral column) reduces overall infection worm load musculature. The isolated were identified as Anisakis simplex sensu stricto by a combination morphometrics molecular methods (PCR rDNA mtDNA, sequencing, BLAST analysis). As...
ABSTRACT In the past couple of decades, applications environmental nucleic acids (eDNA and eRNA) analysis methods have expanded rapidly into various research fields. Recently, World Organisation for Animal Health presented guidelines use eDNA as a biomonitoring tool disease surveillance in aquaculture. this paper, profile Yersinia ruckeri was monitored over course experimentally induced red mouth rainbow trout. Before after mortality started, fish pathogen burden, clinical signs, immune...
Abstract The effects on rainbow trout, Oncorhynchus mykiss (Walbaum), immune parameters by differently formulated fish feed types containing immunostimulants have been tested in a double‐blind, duplicated and controlled study performed over 50 days. A total of 800 trout (10–12 g) were kept eight duplicate tanks (each 100 fish) fed at daily feeding rate 1.5% the biomass. (1) control (C) without additives, (2) beta‐glucan, nucleotides, manno‐oligosaccharides (MOS), vitamins C E (GNMCE), (3)...
The immunological mechanisms associated with protection of vaccinated rainbow trout, Oncorhynchus mykiss, against enteric redmouth disease (ERM), caused by Yersinia ruckeri, were previously elucidated the use gene expression methodology and immunochemical methods. That approach pointed indirectly to both humoral cellular elements being involved in protection. present study correlates level trout reactions spleen head kidney visualizes processes applying histopathological,...
A significant increase in the infection level of Baltic cod Gadus morhua with anisakid nematode larvae Contracaecum osculatum and Pseudoterranova decipiens has been recorded during recent years due to expanding local population grey seals Halichoerus grypus, which act as final hosts for these parasites. Here, we report from an investigation 368 (total length [TL] 6-49 cm; caught ICES Subdivision 25) that juvenile (TL 6-30 cm) C. P. is absent or very low, whereas it increases drastically...
Abstract CK11 is a rainbow trout (Oncorhynchus mykiss) CC chemokine phylogenetically related to both mammalian CCL27 and CCL28 chemokines, strongly transcribed in skin gills homeostasis, for which an immune role had not been reported date. In the current study, we have demonstrated that chemotactic unstimulated leukocyte populations from central organs or mucosal tissues but instead exerts potent antimicrobial activity against wide range of pathogens. Our results show inhibits growth...
The protective immune response in zebrafish (Danio rerio) against the parasitic ciliate Ichthyophthirius multifiliis, targeting host skin, fins and gills, comprises an accelerated manifold elevated immunoglobulin gene expression as well a significantly number of neutrophils at infected sites. Experimental fish were subjected to primary I. multifiliis infection followed by series secondary exposures before they challenged high dosage infective theronts. Immunized responded immediately with...
