The objective of this study was to evaluate the effectiveness of vaccination on tilapia seedlings resulted from the vaccinated parent by hyperosmotic infiltration method at four different salinity to prevent Streptococcus agalactiae bacterial infection. A total of 100 seeds aged 20 days from the vaccinated mother were immersed in four different salinity: 0 ppt (control), 10 ppt, 20 ppt, and 30 ppt for five minutes, then removed and transferred into vaccine-containing containers for 30 minutes. Further maintenance was performed in freshwater aquariums and at days 10, 20, and 30 post vaccination, the immune system performance: Relative Percent Survival (RPS) after the challenge test, specific antibody level, and lysozyme was observed. The study was conducted using a complete randomized design with three replications. The results showed that the 10 ppt salinity treatment gave the best results compared to the others and control. The final RPS (10 ppt) value was 84.72%, 66.49%, and 47.06%, on the 10th, 20th, and 30thh days of vaccination, respectively. Specific antibody levels (10 ppt) were 0.077, 0.078, and 0.077 and lysozyme 0.092, 0.084, and 0.032 at days 10, 20, and 30 post vaccination, respectively. The value of RPS and specific antibody level at 10 ppt salinity was significantly different (P <0.05) compared to the other treatments, while the lysozyme treatment activity of 10 ppt was not significantly different compared to the 20 ppt treatment. Vaccination using 10 ppt saline hyperosmotic infiltration can improve the performance of the immune system by improving maternal immune protection against Streptococcus agalactiae infection.

Streptococcosis is a significant fish disease impacting tilapia culture in Indonesia, causing losses estimated up to IDR 15.0 billion annually. This study aims to assess the efficacy of bivalent and trivalent vaccines containing Streptococcus agalactiae bacteria on tilapia. The formula of the bivalent vaccine contains 75% of S01-196-16 and 25% of N14G isolates (v/v). Trivalent vaccine contains 30%, 35%, and 35% of N14G, NP1050, and SG01-16 isolates (v/v), respectively. A challenge test assessed the efficacy of the vaccines, and it was carried out at 30, 90, and 150 days post-vaccination by artificially infection at LD60. Selected bacteria isolate to be appointed in the challenge test are N14G (biotype 2) and S01-196-16 (biotype 1). Relative Percentage of Survival (RPS) was used as the main indicator of vaccine efficacy. The results revealed that the highest RPS of a bivalent vaccine against S. agalactiae (S01-196-16) was achieved at the first challenge (61.84%), and trivalent vaccine against S. agalactiae (N14G) and S. agalactiae (S01-196-16) was achieved at the first challenge (61.53% and 76.20%, respectively). Bivalent and trivalent S. agalactiae bacteria vaccines are promising “tools” to control streptococcosis on tilapia.

ABSTRACTFish vaccination aims to induce a specific immune response indicated by an increase of antibodies in vaccinated fish. However, in accordance with time the presence of antibodies will continue to decline. The purpose of this study was to determine the kinetics of specifik immune response and trend mortality against Aeromonas hydrophila and Streptococcus agalactiae on tilapia following vaccination with cocktail vaccine. Fish vaccinated through immersion for 30 minutes in a solution of diluted vaccine. Challenge test was performed for three periods, on day 22, 50, and 78 post-vaccination, fish were challenged with single infection of A. hydrophila 108 cfu. mL-1 and S. agalactiae 104 cfu. mL-1 and co-infection of both bacteria by intraperitoneal. During rearing, the blood fish were taken for determining of serum antibodies, and its  measured by ELISA. The results showed that the concentration of specific antibodies vaccinated fish were significantly higher than the control. The basal antibody levels of A. hydrophila before vaccination were higher than S. agalactiae with OD of 0.104 and 0.069 respectively. The maximum  antibody  response  was  reached  within  70  days  of  the  A. hydrophila OD= 0.264 and 56 days against S. agalactiae OD= 0.188. The mortality rate in the control group was significantly higher than vaccinated on all types and each challenge test period. The trend of mortality due to a single infection of A. hydrophila and co-infections occur more quickly than by S. agalactiae. Lowest mortality occurred in the vaccinated group at 50 day tested challenge.Keywords: kinetics antibody, Aeromnas hydrophila, Streptococcus agalactiae, Oreochromis niloticus
