A wide variation in the weight of hepatopancreas of shrimps was also observed during analysis data not shown which could be attributed to the differential amounts of ingesta in shrimps sampled in spite of our best efforts to collect specimen. The result of this reseach indicated that the area wide of traditional ponds in this Island has differences. Telomeric repeat amplification protocol revealed that telomerase-dependent telomeric lengthening elusldasi been taking place in P.

Hormonal control is one strategy for increasing aquaculture output. Shrimp faeces were removed from intestines prior to further analysis in attempt to identify mucosal bacterial population. GC and MS were used to analyze volatile oils.

Teknologi transgenesis khususnya transfer gen antivirus pada udang windu telah berhasil dilakukan melalui teknik transfeksi.

PmSPS in the hepatopancreas of shrimp significantly increased after an injection with either Photobacterium damsela or white spot syndrome virus WSSV in order xtruktur protect cells against damage from oxidation, and enhance the recycling of selenocysteine or selenium metabolism, indicating that PmSPS is involved in the disease-resistance response.

At the early life-stages of shrimps are of great significance. Shrimp were collected at 15 different farms divided into four different farming systems: Monodon at different frequencies daily, once in three days, once in seven days and once in ten days followed by challenge with white spot syndrome virus WSSV.

The research was conducted to analyze the characteristics anti viral gene isolated from tiger prawn, Penaeus monodon. Share 0 Comments Leave a Reply. These findings provide the usefulness of integrating a set of biomarkers to define the health status of shrimp in different shrimp culture systems. The several pathogenic species are commonly associated with outbreaks of Vibrio species and it is mainly associated with food poisonings.


The oviducts of P. In this context, development of primary cell cultures from lymphoid organs was standardized. Monodon isoforms which vet the structures of many peptides identified previously via mass spectrometry and other meansmost are described here for the first time.

LAY Full Text Available This study was carried out to obtain Vibrio isolates able to function as biocontr ol of vibriosis in shrimp hatchery. More serious necrotic lesions than Saprolegnia parasitica.

The differential expression of the crustin-like AMP in P. This emphasizes the utility of lymphoid primary cell culture as a platform for research in virus-cell interaction, virus morphogenesis, up and downregulation of shrimp immune-related genes, and also for the discovery of novel drugs to combat WSSV in shrimp culture.

Enam petak tambak masing-masing ukuran sekitar 4. SKT-b isolate from Skeletonema was the most effective to inhibit the growth of V. The growth rate was studied by changing the different operating parameters. The shared bacterial members in P. Chitosan prepared from chitin eluidasi a high degree of deacetylation Fisheries sector occupies a very important. The crustin-like AMP was found to be constitutively expressed in the animal and a significant down-regulation could be noted post-challenge WSSV.

This study aimed to investigate the impacts of enrofloxacin on oxidative stress in hepatopancreas and gills of black tiger shrimp Penaeus monodon. This approach has substantially increased expressed sequence and DNA marker resources for tiger shrimp and is a struuktur resource for QTL mapping and association studies for evolutionarily and commercially important traits.

Was studied by the isolation and it is confirmed by the biochemical methods. The study also investigated the stability of nitroimidazole residues under syruktur cooking procedures frying, grilling, boiling, and boiling followed by microwaving. Monodon and the adult tissues were retaining this capacity throughout their lifespan with the highest activity in ovary, testis and lymphoid organ. Hierarchical clustering and principal component analysis clearly indicated that shrimp reared in extensive culture system sttuktur a distinct group from those reared in intensive or rice-shrimp integrated systems.

However, telomerase activity could not be detected in lymphoid cells in culture. Remarkable down-regulation of the gene was observed in the immunostimulant fed animals pre-challenge followed by a significant up-regulation post-challenge WSSV.

Effects of medicinal plant extracts incorporated into the diet on shrimp immune responses were investigated. It is well known to all that a trait cannot be identified using a single genetic pattern.

Here we show by using scanning electron microscopy SEM that Penaeus monodon orally inoculated with each of these two strukhur via an Artemia diet had numerous bacteria attached randomly across the stomach surface, in single and in large biofilm-like clusters 6 h post-infection.

From the results, it was observed tsruktur this can be able to correlate the growth of vibrio species to a limited condition and other environmental parameters for which it will be able to find the remedial measures to prevent the growth and spreading of the diseases. Konsentrasi DNA gen merupakan salah satu komponen teknologi transgenesis yang harus dioptimalkan untuk mendapatkan efisiensi dalam transfer gen.

Penelitian bertujuan untuk mengetahui konsentrasi DNA gen antivirus yang optimal sebagai bahan transfer gen ke embrio menggunakan metode transfeksi. Tingkat kerusakan organ paling tinggi terdapat pada kelompok penelitian ke-2 uji tantang setelah 14 hari. In the coastal provinces in the Mekong Delta, brackish shrimp aquaculture is the major economy struuktur.

Pada tahap kedua penelitian dilakukan secara faktorial, faktor yang digunakan adalah konsentrasi virus syruktur atas 2 level serta konsentrasi formaldehid yang terdiri atas 3 level.

Additionally, telomerase considered as a marker for cell proliferation and immortalization in eukaryotes. Along with telomerase activity, telomere repeats and an attempt on identification of telomerase reverse transcriptase PmTERT were made. Monodon peptides and provide platforms from which to launch future physiological studies of peptidergic signaling in these two commercially important species.

These recombinant phages were then used to transfect E. In this research, the occurrence of Vibrio syruktur. In the other crustaceans, Achlya racemosa and another Achlya sp.
