Vaccines made with inactivated cells have produced a relative protection against the sickness, however the administration of subcellular and purified antigens as vaccine could increase the effectiveness of the immune response.Thus, the aim of this work was the determination of antigens of P. damselae subsp. piscicida involved in the specific immune response of S. senegalensis.Fish were immunized by intraperitoneal injection (i.p.) with inactivated extracellular polymeric substances (ECP) and whole cells of P. damselae subsp. piscicida, and Freund's incomplete adjuvant. Two months later fish were boosted with the same antigens. Serum from fish was collected to determine by ELISA the title of antibodies against subcellular fractions of bacteria (ECP, capsule, outer membrane proteins, O antigen and formalized whole cells). Significant differences were found between control and immunized fish, but differences between first immunization and booster were only found for O antigen and capsule.Western blots derived from 2D-PAGE of ECP and Outer Membrane Proteins (OMP), using sole immunized serum, detected two high reactive antigens from ECP. Proteins were identified, by mass spectrometry, as ATP-dependent metalloprotease and Telurite resistance proteins. In the case of OMP, three antigenic proteins were detected and identified as Nrfa Y218f, Anti-oxidant AhpC/TSA, and a protein domain DNA binding heat shock related.
