Introduction
Anita Talbot currently works as a Research Fellow at the Marine and Freshwater Research Centre (MFRC) at the Galway-Mayo Institute of Technology in Galway, Ireland. Her research area of interest is fish health and welfare in aquaculture. Recent projects include the development and testing of bacterial autogenous vaccines for the improved health and welfare of finfish in Irish aquaculture, and investigation into the effects of functional feeds on the innate immune response of Atlantic salmon (Salmo salar), following infection by the ectoparasites Neoparamoeba perurans, the causative agent of Amoebic Gill Disease (ADG) and sea lice (Lepeophtheirus salmonis).

Article
Full-text available
Amoebic Gill Disease (AGD) is a disease affecting cultured Atlantic salmon (Salmo salar) which is caused by Paramoeba perurans. The immunomodulatory impact of functional foods has previously been demonstrated in salmon. The aim of this study was to investigate the role of a novel fish feed in mitigating the severity and progression of AGD in Atlant...
Article
Full-text available
Amoebic Gill Disease (AGD), caused by the protozoan extracellular parasite Paramoeba perurans ( P. perurans ) is a disease affecting Atlantic salmon ( Salmo salar ). This study investigated the gill transcriptomic profile of pre-clinical AGD using RNA-sequencing (RNA-seq) technology. RNA-seq libraries generated at 0, 4, 7, 14 and 16 days post infec...
Article
Full-text available
In aquaculture, recurrence rates of amoebic gill disease (AGD) caused by the ectoparasite Paramoeba perurans are high and no prophylactic strategies exist for disease prevention. In this study, Atlantic salmon (Salmo salar) were initially inoculated with P. perurans and following the development of amoebic gill disease were treated with freshwater...
Article
Full-text available
The causative agent of amoebic gill disease, Neoparamoeba perurans is reported to lose virulence during prolonged in vitro maintenance. In this study, the impact of prolonged culture on N. perurans virulence and its proteome was investigated. Two isolates, attenuated and virulent, had their virulence assessed in an experimental trial using Atlantic...

Amoebic Gill Disease (AGD), caused by the protozoan extracellular parasite Paramoeba perurans , is a disease affecting Atlantic salmon ( Salmo salar ) aquaculture. Many studies to date have investigated the pathogenesis of ADG focusing on the host immune response in the gill after the appearance of clinical symptoms. This study investigated the gil...

Article
The aim of the present work was to investigate the transcriptome response of gilthead sea bream (Sparus aurata) after challenge with the myxosporean Enteromyxum leei, a wide-spread enteric parasite causing heavy economic losses in Mediterranean sparid farms. This parasite causes severe desquamative enteritis which usually leads to death of the fish...
Data
Full-text available
K-means clustering of up-regulated genes (Sets 1, 2, 3). Genes involved in similar pathways or processes are grouped and with the same font (italic/non-italic).
Data
Full-text available
Plasma cortisol levels of control (open circles) and stressed (filled circles) fish. Data are the mean ± SEM (n = 5). Different letters indicate statistically significant changes over the course of the experiment in stressed fish (ANOVA, P < 0.05). Statistically significant differences between stressed and control fish were analyzed at each samplin...
Article
Full-text available
Selection programs for growth and stress traits in cultured fish are fundamental to the improvement of aquaculture production. The gilthead sea bream (Sparus aurata) is the main aquacultured species in the Mediterranean area and there is considerable interest in the genetic improvement of this species. With the aim of increasing the genomic resourc...
Article
This study set out to investigate whether differential expression of genes for acute phase proteins in rainbow trout (Oncorhynchus mykiss) could be induced by confinement stress, a non-invasive method of activating the neuroendocrine stress response. In addition, a second objective was to assess the variation in gene expression between individual f...
Article
Full-text available
In recent years ethical, legislative and economic pressures have created a renewed interest in the development of alternatives to in vivo animal experiments. In vitro studies, particularly those using cell cultures, have been used increasingly as tools to assess the degree of toxicity associated with or present in particular environments. While cel...
Article
Increased levels of differentially regulated trout protein 1 (DRTP1) mRNA transcripts have been reported in fish after activation of the acute phase response. While the function of the DRTP1 protein still remains to be elucidated, this study focused on the genomic organisation of the gene, the quantification of the DRTP1 transcript in various tissu...

Full-text available
A purpose-designed microarray platform (Stressgenes, Phase 1) was utilised to investigate the changes in gene expression within the liver of rainbow trout during exposure to a prolonged period of confinement. Tissue and blood samples were collected from trout at intervals up to 648 h after transfer to a standardised confinement stressor, together w...

Full-text available
Environmental pollutants, including ambient particulate matter (PM), increase respiratory morbidity. Studies of model PM particles, including residual oil fly ash and freshly generated diesel exhaust particles, have demonstrated that PM affects inflammatory airway responses. Neither of these particles completely represents ambient PM, and therefore...

Full-text available
GM-CSF has a major role in the immune and inflammatory milieu of the airway. Airway epithelial cells (AEC) are among the first targets of environmental stimuli and local cytokines, in response to which they can produce GM-CSF. The regulation of GM-CSF is only minimally understood in AEC. We hypothesized that GM-CSF expression in AEC would result fr...

Phagocytic cells provide the first line of defense against mycobacteria. We examined the relative mycobacteriostatic contributions of normal human alveolar macrophages (HAM), peripheral blood monocytes (PBM), and polymorphonuclear leukocytes (PMN) in the early time period after infection with mycobacteria (48 h). Cells were infected with Mycobacter...
Article
Full-text available
The host response to Mycobacterium tuberculosis is characterized by interactions between mononuclear cells, with recruitment and fusion of these cells culminating in granuloma formation. In addition, the host response to M. tuberculosis requires CD4+ T-cell reactivity, mediated by antigen-independent as well as antigen-dependent mechanisms. Thus, w...

Project
The main objectives of this project are to (1) to collect, characterise and culture bacterial isolates from fish species from Irish marine sites (lumpfish, wrasse, salmon) and freshwater sites (perch) and (2) develop the capability to produce and test the efficacy of autogenous bacterial vaccines at GMIT to support Irish-based fish production companies.
