Abstract

This research project aims to we will increment and develop studies of genetic components involved in variations in infection and diseases by myxosporeans of invasive and introduced warm freshwater fish species, increasing knowledge and competences regarding the PhD project in execution. Studies performed until now have shown a large number of new myxosporeans species, as well as different immune response to presence of these parasites found during our research. In this project, studies of identification of strain-specific polymorphic loci in the ssrRNA and internal transcribed spacer-1 (ITS-1) regions of myxosporeans of invasive and introduced freshwater fish, will contributed to know the genetic structure of population of this group of parasite. In the same way, this project aim to find and identify genetic markers that define sympatric and allopatric parasite strains helping to understand the infection patters by myxosporeans. Finally considering that studies about host-specific genotypes has implications for taxonomy, monitoring and management of this significant group of parasites, we consider this project will be of great importance in order to better prevent future disease outbreaks in wild and farmed freshwater fish.
