Outer membrane antigen of A. salmonicida was administered in the single intra peritoneal injection . Test of NBT reduction (both cytochemical and spectrophotometric assay), lisozyme activity, phagocytic ability of PMN neutrophils, levels of g- globulins and total protein, titres of natural and specific antibodies were determined during six weeks after injection. The results obtained showed significant elevation of the cellular and humoral response indices; production of specific antibodies began in the first week yet.
