Exploring the causes of Red Vent Syndrome in Wild Atlantic Salmon (Salmo salar) from coastal waters around ScotlandKent, Alexander January 2018 (has links)
In 2005, Atlantic salmon (Salmo salar L.) migrating to the United Kingdom exhibited swollen, haemorrhagic vents, symptoms not previously recorded. The condition was latterly termed Red Vent Syndrome (RVS), and subsequently observed across the North Atlantic. RVS has been pathognomonically associated with one of the most abundant parasites within the marine environment, the ascaridoid nematode Anisakis simplex, which also causes Anisakiasis in humans. Although A. simplex is commonly found in Atlantic salmon, heavy infestation of the vent region is novel, and the expression of RVS has not been prevalent in other fish species. Red Vent Syndrome has been well studied, however, the causes of the condition, and the reasons driving the novel site of infestation exhibited by A. simplex, have not been clarified. The aim of this PhD therefore, is to provide new information regarding the underlying factors of the infestation of the vent region by A. simplex, and the emergence of RVS. This study therefore: i) assessed the relationship between nematode burdens within the viscera and musculature, in comparison to the vent in 117 adult Atlantic salmon; ii) compared the genetic structure of A. simplex present in the vent region and the viscera using the entire nuclear internal transcribed spacer (ITS) region; iii) investigated migratory route and feeding ground of Scottish salmon populations using stable isotope analysis of dorsal muscle tissue and parasite component communities and, iv) assessed the expression of the cytokine TNF-α1 within vent muscle tissue using (q)RT-PCR, in relation to RVS severity. Phylogenetic analyses have shown that it is A. simplex sensu stricto infesting the vent region. The results show that there is a significant positive relationship between the nematodue burden in the body (viscera and musculature) and in the vent region. Isotopic signatures of salmon populations showed no significant differences, however, A. simplex intensities between populations on the East and North coasts of Scotland suggest geographical differences in A. simplex transmission pathways. Finally, the expression of TNF-α1 is not significantly different between RVS severity, and nematode burden. Out of the four studied factors, increasing nematode intensities in Atlantic salmon populations, and the significant positive relationship of nematode intensities between the body (viscera and musculature) and the vent, are likely to explain the infestation of the vent by A. simplex. The underlying causes of RVS however remain uncertain and require further research. With incidences of RVS observed across a number of populations over a large spatial area, regional and global effectors such as warming sea surface temperatures, and the North Atlantic Oscillation are expected to play key roles in its aetiology.

Caractérisation et modulation de la réponse immunitaire innée au cours de l’infection par le Virus Respiratoire Syncytial en période néonatale / Characterization and modulation of the innate immune response following Respiratory Syncytial Virus infection during the neonatal periodDrajac, Carole 04 July 2018 (has links)
Le Virus Respiratoire Syncytial (VRS) est responsable de 70 % des cas de bronchiolite chez les enfants de moins de cinq ans. La survenue de bronchiolites sévères chez le nourrisson est un facteur de risque de développement d’asthme en grandissant. Aucun vaccin contre le VRS n’est disponible chez l’Homme. Le système immunitaire inné est la première ligne de défense de l’organisme contre les infections. De plus, en interaction avec la flore bactérienne commensale des poumons, l’immunité innée participe à la maturation de la réponse immunitaire adaptative qui confère à l’individu une protection sur le long terme vis-à-vis des pathogènes. Afin d’expliquer la susceptibilité néonatale au VRS, nous avons caractérisé un nouveau mécanisme de contrôle de la réponse innée antivirale lors de l’infection de souriceaux. Nous avons également testé une nouvelle approche de modulation de la réponse immunitaire au VRS par le microbiote pulmonaire. Ainsi, mieux comprendre les mécanismes immunologiques et virologiques responsables de bronchiolites sévères en période néonatale permettra de développer des moyens de lutte sûrs et efficaces contre l’infection par le VRS. / Respiratory Syncytial Virus (RSV) is responsible for 70 % of bronchiolitis in children under five years old. Severe bronchiolitis in infants is a risk factor for asthma development. No vaccine against RSV is available in humans. The innate immune system is the first line of defense against infections. Moreover, in interaction with lung microbiota, innate immunity shapes adaptive immune response responsible for long-term protection against pathogens. To explain the susceptibility of young children to RSV, we characterized a novel regulatory mechanism of the innate antiviral response during neonatal RSV infection in the murine model. We also tested a new approach for modulating immune responses to RSV by the pulmonary microbiota. Thus, a better understanding of immunological and virological mechanisms responsible for severe bronchiolitis during the neonatal period will allow the development of safe and effective therapeutic strategies against RSV infection.
