Centro INCAR successfully achieves re-sequencing of Caligus rogercresseyi genomes and unveils molecular associations with sensitivity to antiparasitic drugs

A study conducted by the “Aquaculture Genomics” line of the Interdisciplinary Center for Aquaculture Research (INCAR) investigated the genomic mechanisms related to pharmacological resistance to pesticides in order to control the ectoparasite Caligus rogercresseyi, also known as the “Sea Louse”.

The research, published in the journal “Frontiers in Marine Science” and authored by Dr. Gustavo Núñez, Constanza Sáez, Dr. Diego Valenzuela, Dr. Valentina Valenzuela, and Dr. Cristian Gallardo, aimed to identify duplications in the genome of C. rogercresseyi associated with sensitivity to pesticides. The study revealed that the intensive use of pesticides in sea louse populations increases the frequency of gene duplications related to molecular and biological processes of interest, such as cuticle thickening.
