DNA analyses and DNA-based diagnoses are going forwardly in the commercial deals with shrimp (Penaeus monodon) as well basic research. In this regard extraction of is obvious. However, numerous protocols available from animal tissue. Therefore, which technique suitable one for tissue indispensable to justify. current study, a protocol was optimized collected Batiaghata, Khulna. Muscle Tissue (M...

Synechocystis MCCB 114 and 115 were segregated as putative probionts for shrimp larvae from a collection of 54 cyanobacterial cultures enriched from seawater. On feeding Penaeus monodon post-larvae with the cyanobacteria, the generic diversity of the intestinal bacterial flora could be enhanced with substantial reduction or total absence of Vibrio spp. A significant difference (p < 0.001) in th...

Among the important challenges to shrimp aquaculture worldwide are the diseases caused by viruses, in particular by white spot syndrome virus (WSSV), which has a genome estimated to contain 305 kb. By analysis and comparison of the WSSV genomic DNA and cDNA libraries, an ORF (vp28 gene) was identified. The gene, encoding a novel 204-amino-acid protein, was expressed in Escherichia coli and puri...

Shellfish allergy is a major cause of food-induced anaphylaxis, but the allergens are not well characterized. This study examined the effects of heating on blue swimmer crab (Portunus pelagicus) allergens in comparison with those of black tiger prawn (Penaeus monodon) by testing reactivity with shellfish-allergic subjects' serum IgE. Cooked extracts of both species showed markedly increased IgE...

The Outer Membrane Protein (OMP) of Vibrio alginolyticus cell wall was administered intramuscularly (IM) to the tiger shrimp (Penaeus monodon Fab.) at 10, 20, 30 μg/kg bw. After 14 days infection, the tiger shrimps were challenged with 10(7) bacterial density of Vibrio harveyi for 24 hours. The total haemocyte count (THC), differential haemocyte count (DHC) and amount of total protein plasma (T...

This study is aimed to assess the heavy metals contamination and health risk in Shrimp (Macrobrachium rosenbergii and Penaeus monodon) collected from Khulna-Satkhira region in Bangladesh. The results showed that the Pb concentrations (0.52-1.16 mg/kg) in all shrimp samples of farms were higher than the recommended limit. The Cd levels (0.05-0.13 mg/kg) in all samples and Cr levels in all farms ...

A portion of the VP28 gene (VP28F118) of white spot syndrome virus was cloned into an expression vector and transformed into E. coli. The objective was to produce a truncated VP28 envelope protein lacking the N-terminal transmembrane region. After induction, the recombinant VP28F118 protein (rVP28F118) was produced, purified by SDS-PAGE and used to immunize Swiss mice for monoclonal antibody pr...

Primary cell cultures from the lymphoid organ of Penaeus monodon were used to investigate in vitro propagation and morphogenesis of white spot syndrome virus (WSSV). Double-strength Leibovitz's L15 supplemented with 20% fetal bovine serum, pH 7.5, with a final osmolarity of 530 +/- 5 mOsm kg-1 was identified as the most suitable culture medium. In this medium, the lymphoid cells remained viable...
