Background: White spot syndrome virus (wssv) is the causing agent for white spot disease in shrimp and many crustaceans. This disease is highly contagious and can cause death within 3–10 days under normal culture conditions. Therefore, early diagnosis of the virus is a necessity. Materials and Methods: Primers were designed for three regions of the virus genome and one region of the shrimp geno...
introduction: white spot syndrome virus (wssv) is one of the most deadly infectious pathogens of the shrimp culture industry. neither effective vaccines nor efficient treatments are currently available for this disease. vibrio species are well known dominant bacterial pathogens in the shrimp ponds. as facultative pathogenic bacteria, it is possible that vibrio spp. along with wssv to co-infect ...
The present resaerch was designed to evaluate the effects of Inactivated Spot White Virus with radiation (gamma irradiant WSSV) on survival rate and immunity factors(THC, TPP, PO, SOD, POD) of white leg shrimp. The experiment was done in Bandar Imam Khomeini hatcheries from November 2013 until February 2014. In this study, the survival rate and immunological parameters of shrimp that exposed ...
An in-situ experiment was conducted to investigate the effect of tropical storm on the white spot syndrome virus (WSSV) loads in Litopenaeus vannamei rearing ponds. White spot syndrome virus loads, heterotrophic bacteria, Vibrio and water quality (including temperature, dissolved oxygen (DO), salinity, pH, NH4-N, and NO2-N) were continually monitored through one tropical storm. The WSSV loads d...
White spot syndrome virus (WSSV), the causative virus of disease, is found in most shrimp farming areas in Iran, and it cause large economic losses to the shrimp farming industry. Shrimp aquaculture is an important industry in Iran and plays an important role in aquaculture production. The shrimp production in 2012 was more than 12000 metric tonnes and it is estimated it will reach 20000 tonnes...

The first genome sequence of a Mexican white spot syndrome virus is presented here. White spot syndrome is a shrimp pandemic virus that has devastated production in Mexico for more than 10 years. The availability of this genome will greatly aid epidemiological studies worldwide, contributing to the molecular diagnostic and disease prevention in shrimp farming.
White spot syndrome virus (WSSV) is one of the major and most serious pathogen in the shrimp industry. As one of the most abundant envelope protein, VP24 acts as a core protein interacting with other structure proteins and plays an important role in virus assembly and infection. Here, we have presented the crystal structure of VP24 from WSSV. In the structure, VP24 consists of a nine-stranded β...
Many shrimp farmers were suffering from White Spot Disease (WSD) onset in last decades. Oscillation of environmental factors could lead mortality in susceptible hosts. Our study was aimed to investigate the effect of different temperatures on juvenile Fenneropenaeus vannamei experimentally exposed to White Spot Virus (WSV). Five hundred and forty juveniles were distributed among 3 treatments in...
