Project description:The parasite species complex Anisakis simplex sensu lato (Anisakis simplex sensu stricto; (A. simplex s.s.), A. pegreffii, A. simplex C) is the main cause of severe anisakiasis (allergy) worldwide and is now an important health matter. In this study, the relationship of this Anisakis species complex and their allergenic capacities is assessed by studying the differences between the two most frequent species (A. simplex s.s., A. pegreffii) and their hybrid haplotype by studying active L3 larvae parasiting Merluccius merluccius.

Project description:Anisakis pegreffii microRNAs from third stage larvae and its released exosomes
Project description:The total proteomes of Anisakis simplex s.s., A. pegreffii and their hybrid genotype have been compared by quantitative proteomics (iTRAQ approach), which considers the level of expressed proteins. A total of 1,976 proteins have been identified using public databases. One hundred ninety six proteins were found significantly differentially expressed; results of pairwise Log2 ratio comparisons among them were statistically treated and supported in order to convert them into discrete character states. This comparison selected thirty six proteins as discriminant biomarkers among A. simplex, A. pegreffii and their hybrid genotype; eighteen of these biomarkers, encoded by nine loci, are specific allergens of Anisakis (Ani s7, Ani s8, Ani s12 and Ani s14) and other (Ancylostoma secreted) is a common nematodes venom allergen.
Project description:We report analyses of the types, amounts and stage-dependence of microRNAsfound in D. immitis culture media recovered after incubating 800,000 microfilariae for 6 days, 500 third-stage larvae (L3) and 500 fourth-stage larvae (L4) for 7 days, as well as 40 adult females and 40 adult males for 48 hours, all separately.
