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

The aquaculture industry in Indonesia has been growing rapidly and plays an important role in rural development and export earning. Penaeid shrimp culture in Indonesia has become a leading export earning in fisheries sector. The main constraint encountered with shrimp culture has always been associated with disease outbreaks, especially, caused by viral agents. The Pacific white shrimp (Litopenaeus vannamei) was unofficially introduced to Indonesia in 1999, and officially approved by Indonesian government in 2001. By the end of 2007, the Pacific white shrimp has been cultured in more than 17 provinces. The Taura Syndrome (TS) disease was detected in Indonesia in 2002, and the disease is currently found in at least 10 provinces. The Infectious Myonecrosis (IMN) is an emerging disease for L. vannamei in Indonesia, first detected in May-June 2006, causing significant mortalities in grow-out ponds. The IMN is characterized by an acute onset of gross signs: focal to extensive whitish necrotic areas in the striated muscle, especially on the distal abdominal segments and tail fan. White necrotic areas become reddened similar to the color of cooked shrimp. The outbreak resulted in elevated mortalities was initially associated with a chronic course of persistent low level mortalities. Up to date, IMN was detected in East Java, Bali, and West Nusa Tenggara provinces. This paper is a brief review of the epidemiological study of IMN disease of Pacific white shrimp in Indonesia: the status of outbreaks, surveillance, and disease diagnosis, and control measures.

Abstract

Pathogen identification based on biochemical properties can barely differentiate Streptococcus iniae and S. agalactiae. Beside that, this technique is also limited by the length of time required to complete the assays. Therefore, rapid diagnosis is necessary to initiate prompt therapeutic and prophylactic measures in order to limit any potential economic losses caused by such pathogens. The aim of the present study was to identify Streptococcosis species using amplification of S. agalactiae DNA sequence with species-specific primer Sdi 61 AGGAAACCTGCCATTTGCG and Sdi 252 CAATCTATTTCTAGATCGTGG and perform phylogenetic analysis based on DNA nucleotide sequence data. The sequencing of PCR products was performed at BPPT Puspiptek Serpong by using the respective PCR primers, Big Dye Terminator Chemistry and AmpliTaq-FS DNA polymerase. The sequencing reactions were run on the ABI Prism version 3103 – Avant Genetic Analyzer (USA) and the result was read by Sequence Navigator program (Applied Biosystem). Alignment multiple analysis was done based on the data from Genebank with BLASTN (http://blast.ncbi.nlm.nih.gov/blast.cgi) on the nucleotide level. Neighbor-joining phylogenetic trees were generated with Genetyx programme version 7 with UPGMA and MEGA software version 4.0. The result revealed that the isolates from brain, eye, and kidney of diseased Tilapia were infected by S. agalactiae and it has 99% similarity with Genebank. It has close relationship with S. agalactiae at genebank with UPGMA method. These isolates showed high variation in the first sequence which is similar to S. iniae. The information of S. agalactiae genomes suggests that gene acquisition, duplication, and reassortment have played an important role in genetic diversity and evolution of S. agalactiae. Screening of breeder fish stocks with the developed PCR methodology, followed by elimination of infected stocks, would provide an efficient strategy to control fish infected by streptococcosis.

Abstract

Penaeid shrimp culture is a major contributor to foreign exchange earning in Indonesia. It has significant impact on economic development of fisheries sector, and leads to be one of prime mover to improve social prosperity. However, shrimp industry particularly black tiger shrimp (Penaeus monodon) has been facing unpredictable situation due to disease problem. The main constrain in correlation to the development of shrimp industry is disease outbreak, especially caused by viral agents. White Spot Syndrome Virus (WSSV) occurred in 1994, causing mass mortality of black tiger shrimp almost in all of the middle and western part of Indonesia. Due to the disease problem, it is estimated that in year 2000, more than 50% of shrimp pond were idle. Pacific white shrimp (Litopenaeus vannamei) or “udang vanamei” was introduced to Indonesia at the end of 1999, and released officially in July, 2001. Response of shrimp farmers to the shrimp rapidly accepted and distributed to many provinces in the country. At the end of 2006, distribution of white shrimp culture was encountered in more than 15 provinces. The seeds are mainly produced from hatcheries located in East Java and Lampung. The information of TSV in Indonesia was reported firstly from East Java at the end of 2002, without a clear history. Since then, survey of TSV distribution was conducted intensively in white shrimp production areas. Beside TSV, population of white shrimp coming to Indonesia also susceptible to White Spot Syndrome Virus (WSSV) and Infectious Hypodermal and Hematopoietic Necrosis Virus (IHHNV) infection. A survey with the aim to know significant viral diseases of white shrimp is needed to set up an alternative strategy to control them. The survey was conducted, firstly in the main production centers of white shrimp; and planned to be continued throughout the country. Samples collection, diagnostic method and data compiled in this study were collected from both active and passive surveillance. Diagnosis of viral diseases infecting white shrimp in this study was focused on TSV, WSSV, and IHHNV agents. Polymerase Chain Reaction (PCR) test has been used as a major diagnostic technique in this study. Progress report of the study showed that TSV spreading limited in controlled areas. The study proved that WSSV and IHHNV have been found in cultured white shrimp. All of the diseases mentioned above tend to be a significant constrain of future white shrimp industry in Indonesia, and special attention should be given in order to protect wide-spread of particular disease from infected to uninfected ones. Also, briefly current status of white shrimp culture development in the country will be discussed in this paper.

Abstract

Epizootic Ulcerative Syndrome (EUS) adalah penyakit pada ikan yang disebabkan oleh infeksi jamur parasitik Aphanomyces invadans. Penelitian ini bertujuan untuk mendiagnosa patogen penyebab penyakit EUS melalui perpaduan 3 (tiga) basis pendekatan, yaitu: (1) gejala klinis, (2), isolasi patogen, dan (3) histopatologis. Sebanyak 30 ekor ikan uji diinfeksi spora jamur A. invadans secara buatan sebanyak 100 spora/ekor ikan melalui penyuntikan secara intra muskular (IM), dan 30 ekor lainnya diinjeksi dengan phosphate buffered saline (PBS) sebagai kontrol. Hasil penelitian menunjukkan bahwa gejala klinis yang muncul adalah timbulnya bercak-bercak merah pada tubuh ikan, selanjutnya berkembang menjadi ulser (ulcer) karena invasi hifa cendawan ke dalam otot/daging ikan. Hasil isolasi jamur dari ulser ditemukan adanya hifa aseptat dengan diameter 7,5-10,0 μm; memproduksi zoospora primer berbentuk cluster achloyd dan zoospora sekunder berbentuk biflagellata. Secara histopatologis ditemukan adanya invasi hifa dan sel granuloma (mycotic dermatitis granulomatosis).
