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

The main problem in the cultivation of tilapia is the attack of bacterial disease Streptococcosiscaused by Streptococcus agalactiae bacteria. Alternative measures to prevent the disease ofStreptocococis can be through the use of phytopharmaca materials. One of the ingredients ofphytopharmaca can be used is cinnamon plant. Cinnamon leaves contain several types of activesubstances such as tannins, eugenol, safrole, calcium oxalate, resin, saponins, tanners, andsinamaldehid. The objective of the study of effectiveness of leaf powder of cinnamon plant toleukocyte differential and phagocytic activity in tilapia (Oreochromis niloticus) infected byStreptococcus agalactiae is to know the influence and dosage of cinnamon leaf powder in feedtoLeukocyte Differentiation and Phagocytosis Activity Postcainfection Streptococcus agalactiaein tilapia (Oreochromis niloticus). This research used 3treatment 4 replication and control withdose K- = challenge test, K+ = without test challenge, A = dose 0,25%, B = dose 0,5%, C = 1%.The parameters observed are Leukocyte Differential and Phagocytosis Activity. Dosage 0.5%addition of leaf powder cinnamon plant on feed is the best dose. Giving of cinnamon leaf powderin feed influenced to increase of leukocyte difference especially on monocyte cell and neutrophilcell was significantly different (P>0,05) than K+ without addition of cinnamon leaf powderwhile phagocytic activity had an effect on Streptococcus agacatiae.

Objectives of this research was to know the effect of probiotic A3-51 supplementation on food to the total number of bacteria in kidney and mortality of Oreochromis niloticus after challenge test with Aeromonas hydrophila and Aeromonas salmonicida achromogenes. This research was consisted of two experiment, the first was to know the highest immunity level of fish based on the number of macrophage and its phagocytic activity. Meanwhile, the second was to know the immunity level of fish challenged with A. hydrophila and A. salmonicida achromogenes by intra-peritoneal injection. The experiment used Completely Randomized Design in triplicates. The result from the first experiment showed that the highest non spesific immune system response, by means number of macrophage, was found 21 days treatment. The second experiment showed that the highest total number of bacteria in kidney and mortality level were 20.23 x 108 cells/g and 46.67%, respectively, both was found in control fish injected intra-peritoneally with A. salmonicida achromogenes.

This study was aimed to enhance the immune response of the broilers by vitamin E and Cod liver oil supplement with locally inactivated bivalent vaccine of Newcastle disease and Infectious bronchitis viruses. One hundred and twenty broiler chicks Ross 308 were divided to four groups at 30 chicks of each group. The 2nd group was vaccinated with 0.5ml/chick of locally inactivated ND-IB vaccine at 5 days old. The 3rd group was vaccinated with 0.5ml locally ND-IB vaccine and 0.1 ml/chick of VE. The 4th group was vaccinated with 0.5ml of locally ND-IB vaccine and 0.1ml/chick of Cod liver oil, while the first group was left without vaccination as a control group. All groups were vaccinated with attenuated ND-IB at 3 days old and attenuated IBD at 14 days old. The results of ELISA test revealed that the 3rd and 4th groups showed significantly increased (P≤0.05) in Ab titers against ND virus at aged 35 days, also, the 4th group showed significantly (P≤0.05) increased in Ab titers against IB virus at day 35 of age as compared with the other groups. The 4th group showed a significant (P≤0.05) increased in bursal index as compared with the other groups. The results of challenge test revealed that vaccinated groups resist the velogenic ND and IB viruses with relatively high productive range particularly the 4th group as compared with other groups. In conclusion, the VE and Cod liver oil supplement with local bivalent oil based vaccine of ND and IBV may enhance the immune response of the broilers particularly the 4th group which vaccinated with 0.5 ml of local bivalent oil based vaccine of ND-IB vaccine and 0.1 ml Cod liver oil.
