Genetic Variation, GWAS and Accuracy of Prediction for Host Resistance to in Farmed Gilthead Sea Bream ().

Gilthead sea bream () belongs to a group of teleost which has high importance in Mediterranean aquaculture industry. However, industrial production is increasingly compromised by an elevated outbreak of diseases in sea cages, especially a disease caused by monogeneans parasite This parasite mainly colonizes gill tissues of host and causes considerable economical losses with mortality and reduction in growth. The aim of current study was to explore the genetics of host resistance against and investigate the potential for genomic selection to possibly accelerate genetic progress.

Genomic analysis of reveals the evolutionary dynamics of sex-biased genes in a sequential hermaphrodite fish.

Sexual dimorphism is a fascinating subject in evolutionary biology and mostly results from sex-biased expression of genes, which have been shown to evolve faster in gonochoristic species. We report here genome and sex-specific transcriptome sequencing of , a sequential hermaphrodite fish. Evolutionary comparative analysis reveals that sex-biased genes in are similar in number and function, but evolved following strikingly divergent patterns compared with gonochoristic species, showing overall slower rates because of stronger functional constraints.

Genetics of resistance to photobacteriosis in gilthead sea bream (Sparus aurata) using 2b-RAD sequencing.

Background: Photobacteriosis is an infectious disease developed by a Gram-negative bacterium Photobacterium damselae subsp. piscicida (Phdp), which may cause high mortalities (90-100%) in sea bream. Selection and breeding for resistance against infectious diseases is a highly valuable tool to help prevent or diminish disease outbreaks, and currently available advanced selection methods with the application of genomic information could improve the response to selection.

Molecular Typing of Vibrio parahaemolyticus Strains Isolated from Mollusks in the North Adriatic Sea.

Background: Vibrio parahaemolyticus is an emerging foodborne pathogen in the Mediterranean, usually associated with shellfish consumption. The increase in the number of outbreaks in Europe is primarily associated with the global warming of the ocean that has a great impact on the spread and genetic selection of waterborne pathogens. The primary role of Italy in Europe's mollusk production, together with the fact that cases of infections with V.

Characterization of thyroid nodules by 3-D contrast-enhanced ultrasound imaging.

High resolution ultrasound imaging proved effective in the detection, analysis, and follow-up of thyroid lesions, even if interpretative pitfalls remain. Differentiation between malignant and benign nodules is a major challenge: malignancy is often correlated to an increase in intranodular vasculature, due to rapid angiogenesis. We developed a three-step methodology to reconstruct intranodular vasculature based on 3-D contrast-enhanced images: i) preprocessing; ii) morphological opening by using a structuring element coherent with the microbubbles appearance: iii) thresholding and 3-D representation.
