Abstract

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 – 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.

Abstract

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.

Abstract

Motile Aeromonas Septicemia (MAS) merupakan penyakit yang sering ditemui pada kegiatan budidaya, dan salah satu komoditas yang sering terserang oleh penyakit ini adalah ikan patin.  Penelitian ini bertujuan mendapatkan dosis terbaik dari simplisia tanaman kipahit untuk mencegah (MAS) pada ikan patin. Percobaan dilaksanakan tanggal 10 Januari 2014 sampai dengan 22 Maret 2014 bertempat di Balai Penelitian dan Pengembangan Budidaya Air Tawar, Sempur, Bogor. Ikan patin dipelihara selama 28 hari sebelum uji tantang dan 10 hari setelah uji tantang dengan perlakuan pakan menggunakan campuran simplisia kipahit dengan dosis 2,44%; 4,76%; 9,09%; dan 16,67%. Perlakuan kontrol adalah pakan komersil tanpa penambahan simplisia kipahit. Hasil penelitian menunjukkan bahwa pemberian pakan seluruh dosis perlakuan, baik sebelum maupun sesudah uji tantang tidak mempengaruhi nilai tingkat kelangsungan hidup, rasio konversi pakan, dan laju pertumbuhan spesifik ikan patin. Pemberian perlakuan setelah dilakukan uji tantang diduga memberikan pengaruh terhadap respon imun terhadap ikan patin, tetapi tidak memiliki aktivitas bakterisidal. Dosis simplisia kipahit terbaik untuk pencegahan MAS pada ikan patin adalah 16,67% karena pada dosis tersebut aktivitas imunostimulan bekerja lebih baik dibandingkan dosis yang lainnya, serta aman terhadap organ hati berdasarkan uji fungsi hati.Kata kunci : Ikan patin, kipahit, Motile Aeromonas Septicemia, pakan.

Abstract

This research aimed to know the toxicity of extracellular products (ECP) of Streptococcus agalactiae was tastedin cultured Nile tilapia (Oreochromis niloticus). Streptococcus agalactiae had two haemolytic types: β-haemolyticand non-haemolytic type. Toxicity test of ECP to know the virulancy factor of S. agalactiae was still limited. It wasfound that after tested on 15 fish weighing 15 g through intraperitoneal injection 0,1 ml/fish, both bacteria causedchanges in swimming pattern, palatability, external and internal anatomy macroscopically and microscopically.Extracellular products of S. agalactiae non-haemolytic type (BHIA and BHI 24 h) and β-haemolytic type (BHI 72 h)caused mortality 12 hours after injection and the mortality continued till day 7 th of culture. Whirling happened 96hours after injection with ECP S. agalactiae β-haemolytic type (BHIA 72 h incubation) whereas injection with ECP(BHI 24 h) on 72 h after injection and continued untill day 7 th. Behavior disease signs caused by S. agalactiaeoccured on eyes. There were opacity, purulens, eye shrink, lateral and bilateral exopthalmia and haemorrhage oninfected-fish. Silver staining of sodium dodecyl sulphate-polyacrylamide gels to S. agalactiae revealed thatpredominant 51.8-69.6 kDa bands were present in BHIA ECP fraction. The 69.6 kDa was absent from the BHI ECP.Total protein on non-haemolytic S. agalactiae ECP are 28.18 ppm on BHIA medium and 13.64 ppm on BHI medium.Whereas β-haemolytic S. agalactiae ECP are 2.73 ppm on BHIA medium and 8.18 ppm on BHI medium. Concentrationof protein in ECP was one of factor that caused non-haemolytic S. agalactiae more virulent than β-haemolytic type.The conclusion from the research that ECP was virulent factor on β-haemolytic and non-haemolytic S. agalactiaein fish which caused changes in behavior disease signs.

Abstract

Carp is a freshwater species that is easily cultivated. One of the constraints in cultivating carps (C. carpio) is diseases that ultimately caused mass mortality. The disease that generally affects carp is Motile Aeromonas Septicemia (MAS) caused by Aeromonas hydrophila. Soursop leaves is one of the herbs that can be used as an ingredient to control fish diseases because it contains chemicals that acts bacteriocide. The purpose of this research was to determine the influence and the best dose of soursop leaf extract in feed to the blood profile and survival of carp infected by A. hydrophila. The treatments of this research were addition of soursop leaf extract on feed with 4 different dosages and 3 replicates. The treatments were A (0 g/kg diet), B (5 g/kg diet), C (10 g/kg diet) and D (15 g/kg diet). The result showed that soursop leaf extract in feed of treatment B (5 g/kg diet) significantly different (P0.05) on total erythrocyte (0.83×106 cells/mm3), differential leukocyte include the percentage of monocytes (7.67%), neutrophils (8.67%), lymphocytes (83.67%), phagocytic activity (37%) and survival rate (50%). It can be conclude that soursop leaf extract at dosage 5g/kg was able to stimulate immune response of carp, it was characterized by an increased total leukocytes of carp infected by A. hydrophila.

Abstract

Lactococcus garvieae is a gram-positive ovoid cocci bacterium formerly classified as a member of the Lactococcus genus. This study aims to isolate L. garvieae from catfish rearing pond and characterize it as a potential probiotic candidate. L. garvieae was identified and characterized through phenotypic and genotypic observation, genomic % G~C content analysis, cell surface hydrophobicity assays, acidification test, in vitro antagonism, and a profile of antimicrobial activities. The MT597595.1 accession number corresponds to L. garvieae, as determined by a molecular identification test. Biochemical characterization was performed using API 50 CH kit. The genomics %G~C content of L. garvieae was 51.8. Findings from acidification ability tests, in vitro antagonism tests, and the ability of bacteria to grow in broth medium at pH 4 reveal that L. garvieae can inhibit the growth of Aeromonas hydrophila, Streptococcus agalactiae, Streptococcus iniae, and Edwardsiella ictaluri. However, it does not suppress the growth of L. garvieae  Edwardsiella tarda. Remarkably, L. garvieae has the ability to reduce the pH of neutral broth medium turning it acidic. Furthermore, L. garvieae’s hydrophobic cell surface exhibited an adhesive, hydrophobic, and protein surface cell content with a compact growth pattern consistent with postive SAT and MATH assay. Antimicrobial activity tests, encompassing 11 antibiotics, disclosed resistance to  Nalidixic acid while displaying intermediate sensitivity to Streptomycin and Trimethoprim. In conclusion, L. garvieae demonstrates an inhibitory effect on the growth of pathogenic bacteria, underlining its potential as a probiotic candidate.

Abstract

Gram-positive spore bacteria are widely used as probiotics in general sectors. However, there are still limited bacterial isolates as probiotic candidates available from indigenous isolates, especially in aquaculture. This study aimed to obtain potential spore-forming isolates as probiotic candidate for tilapia. Tilapia fish samples were collected from Sukabumi, Ciamis, Serang, and Papua. Bacterial isolates were isolated from the digestive tract of tilapia. Bacteria were identified based on their morphological, molecular characteristics, complete genome composition, and cell surface identification based on hydrophobic properties. In this study, six bacteria were isolated and identified by molecular characteristics using 16S rRNA sequences. Based on the phylogenetic analysis, the 9 PP isolate was Priestia megaterium basonym: Bacillus megaterium, CMS 16N isolate was Brevibacillus halotolerans, PPN 10 isolate was Bacillus sp., 3.1 SKBM isolate was Bacillus mycoides, CMS 22 N and SRG32 isolate were Bacillus subtilis. Six bacteria had different phenotypicals, ATGC sequence compositions, and a higher proportion of total G~C sequence composition above 50%. The coherent cell surface hydrophobicity test was positive on the SAT, SA, AA, and compact growth patterns in soft-agar media for 9 PP, CMS 22 N, and SRG32 isolates. From our study, the indigenous spore-forming bacteria isolated from tilapia stomachs are enzymatic bacteria, which have a strong attachment to host tissue and high potential as a probiotic candidate for fish. Various hydrophobicity test results from each isolate indicate that the protein composition in the cell surface is different.
