GRB2, GATA3, IGM, MAVS and Regula genes were used to determine the expression patterns of infectious anemia and drug resistance in Atlantic salmon salar.
Using genes selected from the group consisting of Grb2, Gata3, IgM, MAVS and Regul genenes that serve as predictors to determine susceptible and resistant phenotypes to infectious salmon anemia (ISA) in Atlantic salmon (Salmo salar), quantifying the profile expression of these genes using PCR analysis in real time, and wherein a sample with the expression pattern for a defiance by cohabitation with ISA, which has no significant difference when compared to the expression pattern of these genes in a control sample without defiance by cohabitation to ISA, is indicative of ISA resistant phenotype, namely, which has as a characteristic, less than 40% mortality for the ISA virus and heritability of said character greater than or equal to 0.35; and a sample having a pattern of expression to a defiance of cohabitation to ISA which happens to be low when compared to a control sample without defiance by cohabitation to ISA, is indicative of a susceptible phenotype to ISA, namely, presented as characteristic , a mortality rate exceeding 50% for the ISA virus and a heritability of such minor or equal to 0.34.
