Gene expression in primary hemocyte culture of the Pacific white shrimp Penaeus vannamei infected with different white spot syndrome virus (WSSV) strains

Antisense RNA mediated protection from white spot syndrome virus (WSSV) infection in Pacific white shrimp Litopenaeus vannamei

Immunization 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 ...

Effects 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...

Per os infectivity of white spot syndrome virus (WSSV) in white-legged shrimp (Litopenaeus vannamei) and role of peritrophic membrane

As earlier observations on peroral infectivity of WSSV in white-legged shrimp are conflicting, here, a standardized peroral intubation technique was used to examine (i) the role of the physical composition of the viral inoculum and (ii) the barrier function of the PM. In a first experiment, the infectivity of a WSSV stock was compared by determining the SID50 by intramuscular injection, peroral...
