Abstract

ABSTRACT The aim of this research was to analyse the toxicity and immunogenicity of ECP of non-hemolytic S. agalactiae and to evaluate ECP as a material vaccine for prevention of S. agalactiae. Toxicity to tilapia was detected in the ECP. There was a chronic  mortality pattern which was shown after post ECP injection. By intraperitoneal injection into young tilapia (± 20 g), the median lethal dose were calculated at 633,9 µg/kg bodyweight for isolate 3 and 685,4 µg/kg bodyweight for isolate 5. Cytopathic effects of ECP to tilapiaâ??s lymphocytes were observed during 0, 30, 60 and 180 minutes. A mixture of ECP caused nuclear granulation and cytoplasmic streaming after 60 minutes. Using immunodiffusion analysis, precipitate line was demonstrated against tilapia anti-ECP sera, and there was bio-specific type anti sera against for each isolate. The ECP vaccine effective to protect tilapia from S. agalactiae was injected intraperitoneally (IP) at 2 x 105 CFU/ml. Tilapia vaccinated with ECP from isolat 3 which protein  283 µg/kg bodyweight had a RPS value 60%.  Tilapia vaccinated with ECP from isolat 5 which protein 408 µg/kg  had a RPS value 68%.   Keywords:  toxicity, immunogenicity, extracellular products, Streptococcus agalactiae, tilapia

Abstract

This research evaluated the nonspecific immune responseand growth of Litopenaeus vannamei fednucleotide diet.  In Laboratory, juveniles were reared in two groups of glass aquaria, each with threereplications.  Shrimps in group one were fed nucleotide diet and in group two were fedpellet four consecutiveweeks. Total Haemocyte Count and Phenoleoxydase activity were evaluated at the end of feeding whilegrowth was measured at two weeks interval. At the end of feeding, shrimps were intramuscularlyinjectedwith Vibrio harveyi  0.1x106 cfu.shrimp-1.  In tambak, juveniles were raised in two groups of net cages(hapa), each with three replications. One group was fed nucleotide diet while the other wasfed pellet forfour weeks. Total Haemocyte Count of shrimp fed nucleotide diet significantly increased up to 87% higherthan shrimps fed pellet.  Phenoleoxydase activity of shrimp fed nucleotides diet also increased isignificantlyas compared to shrimp fed pellet (p=0.02). Higher resistance and growth were observed in shrimp fednucleotide diet. In tambak, weight gain of shrimp fed nucleotide was 35.75% greater than shrimp fedpellet. Survival rate (83.24%) was higher than shrimp fed pellet (81.71%).  As conclusion, oral administrationof nucleotide at 400 mg.kg-1 diet could enhancethe nonspecific immune response, resistance, and growth ofL. vannamei.

Abstract

The aim of this study was to investigate effects of Spirulina phycocyanin on the total  blood cell count,phagocytic activity, and growth of humpback grouper fish, Cromileptes altivelis juvenil.  Fishes were fedwith a diet containing   0, 150, 250, 350 dan 450 mg  phycocyanin per kg diet for four weeks and eachtreatment was triplicates.  Initial body weight  of  grouper was  8.46 ± 0.22 g with a density of 10 fish per56 litre volume. The total count of  erythrocytes and leucocytes increased until the fourth week of rearingperiod. The highest of total erythrocyte and leucocytes were observed in fish treated with 150 mg phycocyaninper kg diet ( 13.17 x  105 cells/mm3 and 8.93 x 105 cells/mm3 respectively) which were not significantlydifferent (P>0.05) to those treated with 250 mg phycocyanin per kg diet. The total leucocytes and phagocyticactivity of fish fed diet containing  250 mg phycocyanin  per kg diet (8.49 x 105 cells/mm3 and 59.67%respectively) were significantly higher  (P <0.05) to those of control group. The highest of final weight(Wt=14.32 g) and weight growth (G=5.89g) and lowest of feed conversion ratio (FCR=1.13) were obtainedin fish treated with  250 mg phycocyanin per kg diet which were  significantly  higher  (P <0.05) than thosefed control diet. The data showed that  the addition of  phycocyanin 250 mg/kg diet enhances the totalleukocyte count, phagocytic activity and the growth of humpback grouper juvenil.

Abstract

ABSTRACTInfectious myonecrosis (IMN) disease is a major disease in Indonesia shrimp farming. The disease is caused by infectious myonecrosis virus (IMNV). Currently, treatment and drug has not been obtained to control the virus. This research was conducted to determine the effect of Phyllanthus niruri extract in white shrimp (Litopenaeus vannamei) against IMNV infection. Healthy shrimp was given P. niruri extract 20 mg/kg of feed for seven days and after that the shrimp was challenged by orally with IMNV infected shrimp tissue. The positive control was given feed without P. niruri extract and challenged with IMNV infected shrimp tissue, while negative control was not challenged with IMNV infected shrimp tissue. IMNV infection gave a significantly different effect on survival rate. In the shrimp P. niruri previously (86.7%) gave higher survival rate compared to shrimp without P. niruri (66.67%). Survival rate of negative control was 93.33%. IMNV clinical signs in general was white necrotic areas in striated muscles. Histological examination showed that cell necrosis appeared on the mussel tissues. In conclusion the addition of P. niruri to the commercial feed can give the survival rate of shrimp better when challenged with IMNV.Keywords: IMNV, Phyllanthus niruri, Litopenaeus vannameiABSTRAKPenyakit infectious myonecrosis (IMN) merupakan penyakit utama pada budidaya udang di Indonesia. Penyakit ini disebabkan oleh infectious myonecrosis virus (IMNV). Saat ini, belum diperoleh cara dan obat untuk mengendalikan virus IMNV. Penelitian ini dilakukan untuk mengevaluasi pengaruh immunostimulan tepung meniran (Phyllanthus niruri) yang diberikan melalui pakan pada udang vaname (Litopenaeus vannamei) yang diinfeksi IMNV. Udang vaname yang sehat diberi pakan yang mengandung meniran dengan dosis 20 mg/kg pakan selama tujuh hari dan kemudian diuji tantang secara oral dengan memberikan jaringan udang yang telah terinfeksi IMNV. Udang kontrol positif dilakukan dengan memberi pakan komersial tanpa penambahan meniran yang kemudian diuji tantang dengan memberi makan jaringan udang yang terinfeksi IMNV, sedangkan udang kontrol negatif tidak diuji tantang dengan jaringan yang terinfeksi IMNV. Hasil menunjukkan bahwa kelompok udang yang diberi pakan mengandung meniran mempunyai kelangsungan hidup (86,67%) lebih tinggi dibandingkan dengan udang yang tidak diberi pakan mengandung meniran (66,67%) ketika diuji tantang dengan IMNV. Kontrol negatif yang tidak diberi pakan mengandung meniran dan tidak diuji tantang dengan IMNV memberikan kelangsungan hidup 93,33%. Gejala klinis yang ditunjukkan adanya infeksi IMNV terlihat dengan adanya otot putih pada ruas tubuh udang. Pengamatan histopatologi menunjukkan adanya nekrosis pada sel-sel di jaringan otot udang. Sebagai kesimpulan dapat dinyatakan bahwa penambahan meniran pada pakan komersial dapat meningkatkan kelangsungan hidup udang ketika terjadi infeksi IMNV.Kata kunci: IMNV, Phyllanthus niruri, Litopenaeus vannamei

Abstract

ABSTRACTThis study was carried out to obtain bacteria isolates from coral reef using co-culture method which potentially inhibit Vibrio harveyi growth. A total of 110 isolates were isolated from Acropora sp., Merulina sp., Hystrix sp., Poecillophora sp., Porites sp., and Haliophora sp., and were screened for their antagonistic activity against V. harveyi in in vitro and in vivo test. Five candidate probiotics (5H1 candidate probiotics isolated from Acropora sp., 11I and 11G isolates isolated from Hystrix sp. and 13B and 13G1 isolates isolated from Poecillophora sp., was able to inhibit growth of V. harveyi MR5339 RFR up to 101?102 cfu/mL. Two isolates (13B and 13G1) were not pathogenic at concentration 106 cfu/mL bacteria and could increase of survival rate of tiger shrimp (Penaeus monodon) larvae in in vivo test. Survival rate of tiger shrimp larvae that treatment with 13B and 13G1 were 86,67% and 88,33%, and have a significant different with positive control (61,67%). Partial sequencing of 16S-rRNA showed that 13G1 isolate was similar to V. alginolyticus.Keywords: vibriosis, Vibrio harveyi, tiger shrimp, probiotic, coral reefABSTRAKPenelitian ini bertujuan untuk mendapatkan bakteri probiotik asal terumbu karang dengan metode kultur bersama untuk pengendalian penyakit vibriosis pada larva udang windu (Penaeus monodon). Sebanyak 110 isolat berhasil diisolasi dari Acropora sp., Merulina sp., Hystrix sp., Poecillophora sp., Porites sp., dan Heliophora sp. dan dilakukan penapisan untuk melihat aktivitas kemampuannya melawan Vibrio harveyi MR 5339 RfR dalam uji in vitro dan in vivo. Sebanyak 56 isolat menghasilkan daya hambat terhadap V. harveyi MR5339 RfR pada metode kultur bersama. Lima isolat kandidat probiotik (isolate 5H1 diisolasi dari Acropora sp., isolat 11I dan 11G diisolasi dari Hystrix sp., serta isolat 13B dan 13G1 yang diisolasi dari Poecillophora sp.), mampu menekan pertumbuhan V. harveyi MR5339 RfR hingga 101?102 cfu/mL. Kedua isolat (13B dan 13G1) terbukti tidak bersifat patogen pada konsentrasi 106 cfu/mL dan mampu meningkatkan sintasan larva udang windu pada uji in vivo. Nilai sintasan larva pada perlakuan yang diberi kandidat probiotik 13B dan 13G1 berturut-turut adalah 86,67% dan 88,33%, namun berbeda nyata dengan kontrol positif (61,67%). Hasil analisis sekuen sebagian gen 16S-rRNA menunjukkan bahwa isolat 13G1 termasuk spesies V. algynoliticus.Kata kunci: vibriosis, Vibrio harveyi, udang windu, probiotik, terumbu karang
