Hypoxia increases susceptibility of Pacific white shrimp to whitespot syndrome virus (WSSV)

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 ...

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

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...

Identification of icp11, the most highly expressed gene of shrimp white spot syndrome virus (WSSV).

This study investigates white spot syndrome virus (WSSV) gene expression levels in the cells of 2 hosts (Penaeus monodon and Litopenaeus vannamei). Microarray and expressed sequence tag (EST) analysis of the mRNA profiles in WSSV-infected P. monodon cells were used to identify WSSV genes that were very highly expressed. Results showed that the mRNA of the WSSV icp11 gene consistently had the hi...
