SUPPRESSION OF THE PRIMARY IMMUNE RESPONSE IN RAINBOW TROUT, SALMO GAIRDNERI, SUBLETHALLY IRRADIATED DURING EMBRYOGENESIS

摘要

It is presumptive that bands 29, 30, and 31 represented specific humoral antibody to the immunogenic, Chondrococcus columnaris. It follows that in the greater proportion of fish irradiated at the 4.550 and 40.348 rad levels, bands 29, 30, and 31 were significantly reduced, and undoubtedly accounted for the lowered antibody titers in these test fish demonstrated by agglutination assay.nTotal serum protein levels of all test fish throughout the test period remained the same;however, the Biuret technique here applied may not be sufficiently sensitive to detect the changes observed in bands 29, 30, and 31 by gel electrophoresis.
