APLIKASI VAKSIN Streptococcus agalactiae UNTUK PENCEGAHAN PENYAKIT STREPTOCOCCOSIS PADA BUDIDAYA IKAN NILA (Oreochromis niloticus) [Application of Streptococcus agalactiae vaccine to prevent streptococcosis on tilapia culture, Oreochromis niloticus] Taukhid, Taukhid; Lusiastuti, Angela Mariana; Sumiati, Tuti

The research with the aim to know the effectivity (yield gap) of the application of Streptococcus agalactiae vaccine (pure whole cell) in prevention of streptococcosis on tilapia (Oreochromis niloticus) culture has been carried out. The isolate of S.agalactiae â N14G was used as a master seed on vaccine production. Priming vaccination was administered by immersion method, and booster vaccination was taken th place two months latter by oral method. Challenge test at the lethal dose (LD50) against active bacteria was done at 14 days post booster vaccination, and observation was taken place for 14 days post artificial infection. The results of the research showed that the highest survival rate and relative percent survival (RPS) was found in group treated with Streptovac vaccine (S. agalactiae and A. hydrophila combination) (65.58% and 35.36%) followed by S. agalactiae vaccine (52.08% and 10.01%). The lowest survival rate was found in control group (46.75%). The result of confirmation effectivity of the vaccines by challenge test in the laboratory showed that the highest survival rate and relative percent survival (RPS) was found in S. agalactiae vaccine (50.00% dan 37.50%) followed by Streptovac vaccine (40.00% and 25.00%), and the lowest survival rate was found in control group (20.00%). Vaccination is better than the non vaccinated.

OPTIMASI FREKUENSI PEMBERIAN VITAMIN C PAD A PAKAN KOMERSIAL UNTUK PENGENDALIAN PENYAKIT KOI HERPES VIRUS (KHV) PADA IKAN MAS (Cyprinus carpio Linn.) Taukhid, Taukhid; Lusiastuti, Angela Mariana; Suryadi, Kusumasari; Rosidah, Rosidah; Setiadharma, Gunawan

The research with objective to understand optimization frequency of supplemented ascorbic acid (microencapsulated vitamin C CFC-90) feeding to control the Koi Herpes Virus (KHV) disease infecting common carp has been done in Fish Disease Laboratory Fishes were reared in plastic container (80 litres), with density of 20 fish sized 10 gram in average. The treatments were: (A) daily application, (B) three daily application, (C) five daily application, and (D) without vitamin C as a control. Examined fishes were challenged to KHV infection after the 21 days rearing period by cohabitation method for 2 weeks. Observations been done on behaviour, clinical signs and mortality of fishes. The results showed that the highest survival rate was found on the application o vitamin C given every 3 days (50.0%); followed by every day (12.5%), every 5 days (7.5%), and the lowest was found on contro group (1.3%). Control techniques in the case of KHV carp populations through the provision of vitamin C immunostimulatory conducted regularly since well before the existence of KHV infection provides the best protective level.

Aeromonas hydrophila is a pathogen that often causes considerable losses in the area of freshwater fish fanning. Vaccination is one way to simulate parent catfish make specific immunity. Specific immunity generated by the parent will be forwarded through the oocytes produced during a certain time span. The aim of this research was to know the effect and the effectivity of using hydrovac vaccine with and without the complete adjuvant. This research was done on Patin fish Pangasionodon hypophthalmus whose givng Hydrovac 0.4 ml/kg of body weight. The comparation between complete adjuvant and vaccine was 1:1. Injection was done by intra peritoneal for three mothers each with and without complete adjuvant. Injection was done at gonad maturity level II. The result showed that antibody were positively detected on mother serum which used adjuvant or not. On larva stage, antibody was detected until four weeks old. While on 2 weeks old of larva, the concentration of titer antibody was very high and raised the dilution of 1: 2048. Survival rate of juvenile which their mother got a vaccine raised 93%, was better than 73%-63% using mother without vaccine. Booster immersion of hydrovac vaccine could give preferably at the end of three weeks old or in the beginning of fourth weeks old of larva.
