Abstract

Motile aeromonas septicemia/MAS diseases due to Aeromonas hydrophila infection is an obstacle in cultivation of catfish (Pangasius hypophthalmus). MAS control can be done by administering vaccines. The purpose of this research is to get the right and effective dose of bivalent vaccine for controlling MAS at catfish. Both isolates will be used as vaccines are local strains of A. hydrophila CASO.01.G and SBMI.2. Both of them were isolated from disease catfish in the aquaculture ponds in Cindai Alus and Sungai Batang villages, Banjar Regency, South Kalimantan. Vaccines are made by heating (heat killed) at 100oC for 60 minutes. A total of  13 test catfish measuring 9-13 cm were included in each aquarium. The design used was a completely randomized design with 5 treatments and 3 replications, namely bivalent vaccine with a dose of 109 cells/ml, 108 cells/ml, 107 cells/ml, 106 cells/ml, and control (PBS solution pH 7.0). The highest antibody titers in treatments vaccinated fish at a dose of 107 cells / ml (1,706.67). The effectiveness of the vaccine can be seen by the high RPS value of the treatment dose 109 cells/ml (97.22%); 108 cells/ml (100%); 107 cells/ml (97.22%); and 106 cells/ml (100%). The control MTD value was 1 day with 97.43% mortality, while in the vaccine treatment with dose of 107 cells/ml, there was a MTD repeat value for 1 day, but only 1 fish died. Water quality of this research are supportive and not a cause of fish death during the challenge test

Abstract

Objectives of this study were to find out the protein of Aeromonas hydrophila for vaccine, and to evaluate the efficacy of the protein to control Motile Aeromonas Septicemia (MAS) in catfish (Pangasius hypophthalamus). A. hydrophila was isolated from the kidney of diseased catfish. The isolate was cultured, sonicated and sentrifuged into cell-free extract and debris. The protein in the cell-free extract was precipitated with ammonium sulphate, dialized, then fractionated by gel filtration column chromatography on Sephadex G150.The concentration of protein were estimated by spectrophotometer at 280 nm. Fractions obtained from the gel filtration with high concentration of protein were analized by sodium dodocyl sulphate-polyachrylamide gel electrophoresis (SDS-PAGE). The protein bands obtained from SDS-PAGE with molecular weight more than 10 kDa were tested for immunogenicity to mice. Futhermore, the most immunogenic protein was used for fish vaccination. The vaccinated and unvaccinated fishes were chalenged with A. hydrophila.The results indicated that vaccination with the protein significantly increased (P<0.01) the antibody titer either in mice or catfish. Relative Percent Survival of catfish vaccinated with the protein at 5; 7.5; and 10 µg/fish were 61.54%, 80.77% and 76.92%, respectively. The optimum dose of vaccine was 8.33 µg/fish with maximum RPS of 82.05%.

Abstract

This study aims to determine the vaccine A.hydrophila ASB-01 is effective forthe control of MAS on snakehead fish. Effectiveness of vaccination was evaluated through the antibody titer, survival, RPS (relative percent survival) and RWK (meantime of death). The study consisted of 5 treatments (immersion vaccination (R), oral(O), intramuscular injection (IM), intraperitoneal injection (IP) and control (PBS pH7.0) with 3 replications. Vaccination doses were 107 cells / ml. Booster vaccination after 14 days later. Dose is equal to the initial vaccination. Furthermore, the next day14 fish were challenged with A.hydrophila ASB-01. To obtain data on antibody titerblood draw done at the time before being vaccinated, shortly before the booster vaccination and 14 days after the booster vaccination. Challenged fish were observedfor 14 days to obtain data on survival, RPS and RWK. The result showed that allthese vaccines may increase the antibody titer, but the highest antibody titers obtained from fish vaccinated injection. Survival rates were vaccinated IM (84.47%), IP(82.20%), R (42.27%), O (42.20%) and controls (13.13%). RPS to IM (82.08%), IP(79.46%), R (33.38%), O (33.31%), while RWK through the IP (3.63 days), IM(79.46 3.57 days), R (2.46 days), O (1.85 days) and controls (1.03 days). Effective vaccination route is through injection.
