SEM also revealed the induced production of peritrichous pili-like structures by the Vp attaching to the stomach lining, whilst only a single polar fibre was seen forming an apparent physical bridge between Vh and the host’s epithelium.

Meskipun demikian optimalisasi komponen teknologi tersebut masih perlu dilakukan. Sampling pertumbuhan, kualitas air, dan bakteri dilakukan setiap dua minggu sekali. This work provides the first comprehensive report on bacterial populations in the intestine of adult black tiger shrimp and reveals some similar bacterial members between the intestine of wild-caught and domesticated shrimp.

Hierarchical clustering and principal component analysis clearly indicated that shrimp reared in extensive culture system formed a distinct group from those reared in intensive or rice-shrimp integrated systems. It is necessary to know if tiger shrimps grow well in such salinity, since the optimum salinity range for the growth of tiger shrimp is 15—25 ppt.

This ismainly because of the addition of lecithin which is a relatively expensive dietary ingredient. The shared bacterial members in P. This approach has substantially increased expressed sequence and DNA marker resources for tiger shrimp and is a useful resource for QTL mapping and association studies for evolutionarily and commercially important traits. The relative crystalline structure of the chitin and chitosan were Experimental infection showed that smaller and thin-shelled crustaceans were more.

Parahaemolyticus Vp have long been considered as shrimp pathogens in freshwater, brackish and marine environments. Sake S were noted during the study. An Illumina iSelect genotyping array containing 6, SNPs was developed and used to genotype offspring belonging to seven full-sibling families. Intestinal bacterial profiles were compared using denaturing gradient gel electrophoresis DGGE. Via an established bioinformatics workflow, 41 L.


Additionally, telomerase considered as a marker for cell proliferation and immortalization in eukaryotes. The experiments were carried out in shrimp muscle tissue containing both high and low concentrations of these residues. However, telomerase activity could not be detected in lymphoid cells in culture. It is well known to all that a trait cannot be identified using a single genetic pattern.

As diet cost representsthe largest variable cost in a commercial aquaculture operation, increased knowledge of specific dietaryrequirements is essential for formulating a cost-effective commercial P.

LAY Full Text Available This study was carried out to obtain Vibrio isolates able to function as biocontr ol of vibriosis in shrimp hatchery. HMMNI residues were only detectable up to d1 0.

Incorporating the medicinal extracts at higher levels resulted in reduction in diet palatability which consequently had an effect on a decrease in growth, immune responses and resistance to bacterial and WSSV infection. There are andrographolide,deoxydidehydroandrographolide and neoandrographolide.

Theshrimp weight varied from 3. In global trade, fish and fishery products are among the most sought after of various agricultural commodities. This calls for strengthened pollution control measures in order to conserve this commercially important species.

Elusidasi Struktur Molekul Uk-3, Uk-4 Dan Uk-5, Senyawa Bioaktif Dari Streptomyces SP. 517-02.

Fish and fishery products represent one of the most valuable and nutritious food item for humans having most of stguktur essential nutrients for human health. The linkage groups consisted of elusidaai and markers, of length between To study the water qualityparameters and to study the growth and survival of animals feed containing different percentage oflecithin.

The identified peptides included isoforms of allatostatin A, B and C, as well as members the bursicon, CAPA, CCHamide, crustacean cardioactive peptide, crustacean hyperglycemic hormone, diuretic hormone 31, eclosion hormone, FLRFamide, GSEFLamide, intocin, leucokinin, molt-inhibiting hormone, myosuppressin, neuroparsin, neuropeptide F, rlusidasi, orcomyotropin, pigment dispersing hormone, proctolin, red pigment concentrating hormone, RYamide, SIFamide, short neuropeptide F and tachykinin-related peptide families.

The bacteria density in haemolymph, haemolymph of the hepatopancreas and gills decreased with time. After injected with either Photobacterium damsela or white spot syndrome virus WSSVthe respiratory bursts of shrimp significantly increased in elusidxsi to kill the strkutur, and induced increases in the activities of superoxide dismutase and GPx, and regulation in the expression of cloned GPx mRNA to protect cells against damage from oxidation.


To examine the structure of the oviduct of the shrimp Penaeus monodon. PmSPS in the hepatopancreas of shrimp significantly increased after an injection with either Photobacterium damsela or white spot syndrome virus WSSV in order to 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.

Isolasi gen anti virus menggunakan metode Polymerase Chain Reaction PCR dan selanjutnya dipurifikasi untuk sekuensing. Survey, interview and observation.

The library is 7. GC and MS were used to analyze etruktur oils.

In this study, we employed a barcode pyrosequencing analysis of V regions of 16S rRNA genes to examine intestinal bacteria communities in wild-caught and domesticated P. An understanding therefore, of molecular responses and defense mechanism s in shrimps against bacterial pathogens is essential.

The study was divided into two phases, the first phase was to determine the VID50 Virus Infective Doze using Completely Randomize Design, the second phase was to determine of effectiveness of inactive WSSV antigen on the immune response of Penaeus monodon, behavior and pathological respond of Penaeus monodon larvae.

Transfeksi dilakukan dengan menggunakan media larutan transfeksi jetPEI dengan konsentrasi DNA gen antivirus sebagai perlakuan, yakni: Bakteri ini dapat tumbuh pada suhu 40oC, salinitas ppt, dan sensitif terhadap beberapa jenis antibiotik seperti rifanpisin, eritromisin, elusieasi klorampenikol akan tetapi resiten terhadap ampisilin, oksitetrasiklin, gentamisin, dan furazolidon. In this research, the occurrence of Vibrio sp. These recombinant phages were then used to transfect E.
