Design and Evaluation of a PCR Method for Detecting White Spot Syndrome Virus in Shrimp
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...
متن کاملImmunization of Litopenaeus vannamei shrimp against white spot syndrome virus (WSSV) by gamma-irradiated WSSV plus Vibrio paraheomolyticus
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 ...
متن کاملGenotyping of white spot syndrome virus prevalent in shrimp farms of India.
DNA extracts from white spot syndrome virus (WSSV) that had infected post-larvae and juveniles of cultured shrimp, wild shrimp and crabs, which had been collected from different hatcheries and farms located along both the east and west coasts of India, revealed considerable variation in several previously identified WSSV DNA repeat regions. These include the 54 bp repeat in ORF 94, the 69 bp re...
متن کاملEffects of dietary astaxanthin on the immune response, resistance to white spot syndrome virus and transcription of antioxidant enzyme genes in Pacific white shrimp Litopenaeus vannamei
Three different experiments were conducted to study the effect of dietary astaxanthin on the immune response, resistance to white spot syndrome virus (WSSV) and transcription of antioxidant enzyme genes in Pacific white shrimp Litopenaeus vannamei. Each experiment included one triplicate treatment group (fed with 80 mg/kg astaxanthin supplemented diet) and one triplicate control group (fed with...
