News Insights into the Host-Parasite Interactions of Amyloodiniosis in European Sea Bass: A Multi-Modal Approach.

Amyloodiniosis is a disease resulting from infestation by the ectoparasitic dinoflagellate (AO) and is a threat for fish species such as European sea bass (ESB, ), which are farmed in lagoon and land-based rearing sites. During the summer, when temperatures are highest, mortality rates can reach 100%, with serious impacts for the aquaculture industry. As no effective licensed therapies currently exist, this study was undertaken to improve knowledge of the biology of AO and of the host-parasite relationship between the protozoan and ESB, in order to formulate better prophylactic/therapeutic treatments targeting AO.

Innate immune-gene expression during experimental amyloodiniosis in European seabass (Dicentrarchus labrax).

The ectoparasite protozoan Amyloodinium ocellatum (AO) is the causative agent of amyloodiniosis in European seabass (ESB, Dicentrarchus labrax). There is a lack of information about basic molecular immune response mechanisms of ESB during AO infestation. Therefore, to compare gene expression between experimental AO-infested ESB tissues and uninfested ESB tissues (gills and head kidney) RNA-seq was adopted.

Transcriptome Analysis of Tomonts Revealed Basic Information on the Major Potential Virulence Factors.

The ectoparasite protozoan (AO) is the etiological agent of amyloodiniosis in European seabass () (ESB). There is a lack of information about basic molecular data on AO biology and its interaction with the host. Therefore, de novo transcriptome sequencing of AO tomonts was performed.

Comparative Therapeutic Effects of Natural Compounds Against spp. (Oomycota) and (Dinophyceae).

The fish parasites spp. (Oomycota) and (Dinophyceae) cause important losses in freshwater and marine aquaculture industry, respectively. The possible adverse effects of compounds used to control these parasites in aquaculture resulted in increased interest on the search for natural products with antiparasitic activity.

Expression of infection-related immune response in European sea bass (Dicentrarchus labrax) during a natural outbreak from a unique dinoflagellate Amyloodinium ocellatum.

In the Mediterranean area, amyloodiniosis represents a major hindrance for marine aquaculture, causing high mortalities in lagoon-type based rearing sites during warm seasons. Amyloodinium ocellatum (AO) is the most common and important dinoflagellate parasitizing fish, and is one of the few fish parasites that can infest several fish species living within its ecological range. In the present study, A.

Insomnia, quality of life and psychopathological features.

Most of the studies about chronic insomnia focused only on specific features, providing in this way a partial outlook of the problem. The aim of this study was to examine a sample of chronic insomniacs from different points of view, by estimating the prevalence of stress, psychopathological symptoms, psychiatric disorders, changes in quality of life and illness behaviour. Forty-three patients (54.
