Abstract

The aim of this study was to evaluate the effectiveness of vaccination based on gonad maturationstages on tilapia brood stocks in which the released antibodies was able to be transferred to the seed.Vaccine composed with whole cells and extracellular product (ECP) was injected at stage 2 and stage 3 ofthe gonad development stages at concentration of 109 CFU mL1 as much as 4 mL to 1 kg of brood fish.Control fish was unvaccinated treatment. Challenge study at seed was conducted by immersing S. agalactiaefor 30 minutes at 7, 14, 21, and 28 days post hatching (DPH) in 107 CFU/mL. Antibody levels on broodstocks, eggs, and body fluids of seed, and relative percentage survival (RPS) of seed post challenge studywere evaluated. The results showed that stage 2 of gonad developmental stages was found on 7 days postinitial spawning and stage 3 found on 14 days post initial spawning of brood fish. Vaccinated done in stage 2 of gonad developmental stages gave immunoglobulin serum in brood (0,166±0,001), egg (0,165±0,002),and seed aged 7, 14, 21, and 28 days post hatching (0,164±0,002, 0,162±0,005, 0,155±0,006, and 0,14±0,008respectively) were significantly higher (P<0,05) compared to other treatment. Challenged test that doneby immersing with S. agalactiae suspension on larval aged 7, 14, 21, and 28 days had highest RPS(95,24%, 83,33%, 72,22%, and 56,02% respectively) formed on seed from brood stock vaccination in gonaddevelopment stage 2. Vaccination in tilapia brood stocks at stage 2 of gonad developmental stages gavehighest protection by maternal immunity to the seed against S. agalactiae.

Abstract

One of the disease that often led to mortality in catfish resulting in harvest failure is Motile AeromonadsSepticemia (MAS) caused by infection of Aeromonas hydrophila. To avoid this situation, the preventionand control of disease is very crucial. An environmentally friendly approach acceptable in aquaculture isthe use of probiotics to control the pathogenic infection. African catfishes used in the study weighted of1,97±0,7g/fish, and were maintained in the aquarium size of 56x39x34 cm3filled with 30 liters of waterwith stock density of 25 fishes . Probiotic was given daily for 28 days. This research was consisted of 6treatments; (A) AH26 NAR103 CFU/mL, probiotics ND2 CefR 105 CFU/mL dan P23 CipR 105 CFU/mL ; (B)AH26 NAR103 CFU/mL, probiotics ND2 CefR 103 CFU/mL dan L1k TetR 103 CFU/mL; (C) AH26 NAR103CFU/mL, probiotics P23 CipR 104 CFU/mL dan L1k TetR 104 CFU/mL; (D) AH26 NAR103 CFU/mL, probioticsND2 CefR 105 CFU/mL, P23 CipR 105 CFU/mL dan L1k TetR 105 CFU/mL; (K+) AH26 NAR103 CFU/mL, without probiotics; (K-) Without the addition of probiotics and without AH26 NAR in the media. Eachtreatment has 3 replications. The results showed that the combination of probiotics ND2CefR103CFU/mLand L1k TetR103CFU/mLcan supressedA. hydrophila cell density up to 40% lower, induced immuneresponses (hematocrit level and respiratory burst activity) and increased the survival rate of catfishuntilthe end of the research.

Abstract

The effectiveness of Streptococcus agalactiae vaccine in tilapia (Oreochromis niloticus) was evaluatedfor prevention of streptococcal disease. The vaccine was prepared using formalin-killed whole cell andconcentrated extracellular products/ECP (62.3 and 55.8 kDa) of â-haemolityc isolate and 62.3; 55,8 and51.8 kDa protein of  non-haemolityc ECP of S. agalactiae.  Vaccination and challenged (103 colony-formingunits (CFU)/fish of â-haemolityc and 105 CFU/fish of non-haemolityc S. agalactiae) trial was conducted byintraperitonial (IP) injection into fish with average body weight of 15 g.  Fish were vaccinated with wholecell, ECP and mixed (whole cell and ECP) vaccine.  Tilapia vaccinated with whole cell of â-haemolitycisolate had a relative percent survival (RPS) rates higher than those of ECP â-haemolityc vaccine. However,fish  vaccinated with mixed (whole cell and ECP) of â-haemolityc has a better protection rates as comparedto those of two type of S. agalactie infection. Whereas those vaccinated with mixed (whole cell non-haemolitycand ECP of â-haemolityc) vaccine has protection rate of 79% from â-haemolityc and 42% from non-haemolitycinfection.  Tilapia vaccinated with whole cell of non-haemolityc was only able to protect fish from non-haemolityc infection and was unable to protect fish from other types.  Tilapia vaccinated with ECP non-haemolityc had a worse RPS than others vaccines in which mix whole cell and ECP vaccine of non-haemolitychad a protection 50-56% from  S. agalactiae infection. Whereas vaccinated with mixed (whole cell â-haemolityc and ECP of non-haemolityc) vaccine showed a better to protect from â-haemolityc than non-haemolityc infection.  It showed thatvaccination with mixed (whole-cell and extracellular product)  vaccineof S. agalactiae â-haemolityc  was more effective to protect tilapia against Streptococcosis.

Abstract

Streptococcus agalactiae was isolated from cultured Nile tilapia (Oreochromis niloticus) in Cirata gulfand Klaten. The isolates were Gram positive cocci, oxidative fermentative positive, motility, and catalasenegative, grown on media containing NaCl 6.5%, ?-haemolytic and non-haemolytic. Two types of S. agalactiae(?-haemolytic and non-haemolytic) are different from their variety of sugars fermentation. Strains ?-haemolytic can ferment more sugars, including arabinose, sorbitol, lactose, and trehalose. Experimentalinfectivity trials on Nile tilapia (size 15 g), non-haemolytic type showed more virulent. This type causedfaster mortality, more severe behavior changes, and pathology changes than â-haemolytic type. NonhemoliticS. agalactiae caused 48% mortality 6-24 hours after injection, whereas â-haemolitic type caused17% mortality which it occured in 48 hours after injection (mortality of fish control 2,22%). Behaviordisease signs caused by non-haemolitic S. agalactiae started to happen 6 hours after injection whereas 12hours in ?-haemolytic type infection. Histopatological changes were observed on fish eye, spleen, andbrain. Hyperaemia, hyperthrophi, degeneration, and necrosis were also found on infected fish. Thisresearch was concluded that non-haemolytic of S. agalactiae was more virulent than ?-haemolytic.
