White Spot Syndrome Virus (WSSV) is an infectious pathogen of shrimp and other crustaceans, and neither effective vaccines nor adequate treatments are currently available. WSSV is an enveloped dsDNA virus, and one of its major envelope proteins, VP28, plays a pivotal role in WSSV infection. In an attempt to develop a vaccine against WSSV, we inserted the VP28 gene into a baculovirus vector tail...

Several oral vaccination studies have been undertaken to evoke a better protection against white spot syndrome virus (WSSV), a major shrimp pathogen. Formalin-inactivated virus and WSSV envelope protein VP28 were suggested as candidate vaccine components, but their uptake mechanism upon oral delivery was not elucidated. In this study the fate of these components and of live WSSV, orally intubat...

White spot syndrome (WSS) is a viral disease which affects most of the commercially cultivated marine shrimp species all over the world causing significant losses. Deaths occur within days of symptoms and affect a diverse range of commercial crustacean species. A heavy mortality is usually observed in the entire infected population. Survival rates can be anywhere from 30% to zero. Consequently,...

White spot disease (WSD) is caused by the white spot syndrome virus (WSSV), which results in devastating losses to the shrimp farming industry around the world. However, the mechanism of virus entry and spread into the shrimp cells is unknown. A binding assay in vitro demonstrated VP28-EGFP (envelope protein VP28 fused with enhanced green fluorescence protein) binding to shrimp cells. This prov...

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...

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...

White spot syndrome (WSS) is one of the most common and most disastrous diseases of shrimp worldwide. It causes up to 100% mortality within 3 to 4 days in commercial shrimp farms, resulting in large economic losses to the shrimp farming industry. VP28 envelope protein of WSSV is reported to play a key role in the systemic infection in shrimps. Considering the most sombre issue of viral disease ...

چکیده یکی از مهمترین مشکلات صنعت آبزی پروری به ویژه تولید میگو، خسارت بالای ناشی از بیماری های ویروسی است. بیماری لکه سفید میگو یکی از شایع ترین بیماری های ویروسی می باشد. ژن vp28 مهمترین ژن عامل بیماری در پوشش سلولی ویروس است که خاصیت ایمینولوژی آن در تولید واکسن به اثبات رسیده است. در این تحقیق امکان تولید واکسن خوراکی برای میگو با انتقال ژن vp28 به میکروجلبک مورد بررسی قرار گرفته است. ژن vp...

White spot syndrome virus (WSSV) is a highly pathogenic and prevalent virus affecting shrimp culture worldwide including Iran. In the present study, a pair of primers was designed according to the sequence of VP 28 gene of WSSV in the GenBank. VP28 gene from an Iranian WSSV isolate (IrVP28) was cloned, sequenced and expressed in Escherichia coli BL21(DE3) strain in order to produce VP28 protein...

Cell surface display using the yeasts Saccharomyces cerevisiae and Pichia pastoris has been extensively developed for application in bioindustrial processes. Due to the rigid structure of their cell walls, a number of proteins have been successfully displayed on their cell surfaces. It was previously reported that the viral binding protein Rab7 from the giant tiger shrimp Penaeus monodon (PmRab...
