Aeromonas hydrophila is one of the most important pathogenic bacteria in fishes that cause bacterial septicemia. In this study, 120 pieces of common carp (Cyprinus carpio) weighting 30-70g, were divided in to five different groups (two groups of 30 pieces and three groups of 20 pieces in each). Formalin killed Aeromonas hydrophila were injected intramuscularly and intra-peritonealy to two groups (each group 30 fish). As a control, normal saline were injected intra-muscularly and intra-peritonealy to two groups (each group 20 fish) and one group (20 fish) was not received injection. Blood samples were collected from all fishes 2 weeks after injection and titer of anti-Aeromonas antibody determined by tube agglutination test. Antibody titer in intra-muscular injected group was significantly higher than normal saline injected group. Antibody titer in intra-peritoneal injected group was also significantly higher than normal saline injected group (P< 0.05). The result showed that there was a significant difference between titer of killed bacteria received groups in comparison with control groups (P<0.05), but there was not significant difference (P>0.05) between titer of intra-muscular and intra-peritoneal becterin received groups. According to our results, injection of killed bacteria in both methods of injection, significantly elevated the serum antibody level.
