Infectious disease constitutes a major obstacle to the sustainability of shrimp aquaculture worldwide and a significant threat to natural populations of shrimp and other crustacea. The study of the shrimp immune system, including the response to viral infection, has been hampered by a relative lack of molecular genetic information and of tools suitable for high-throughput assessment of gene exp...
In this research, White spot syndrome virus (WSSV) with 105.4LD50.mL-1 inactivated with gamma irradiation at a dose rate of 14-15 kGy.sec-1 was used as a vaccine. Three hundred and sixty shrimp of Litopenaeus vannamei, medium body weight (MBW) 1.0±0.17g), were prepared and experimentally exposed. They were distributed among four groups, inclusing vaccinated-virus exposed (T1), vaccinated-nonvir...
This is the first report of natural white spot syndrome virus (WSSV) infection in wild and large-scale farmed crawfish. In the spring of 2007, 3 crawfish farms experienced heavy mortality in ponds populated by Procambarus clarkii and P. zonangulus. Histological examination revealed findings consistent with severe viral infection characterized by numerous intranuclear inclusions in ectodermal an...
The Vembanad Lake located on the south-west coast of India, an ecological hotspot is the nursing ground of many economically important crustaceans. The prevalence of white spot syndrome virus (WSSV) among crustaceans from farmed, estuarine and marine environments surrounding the Vembanad Lake, India was detected using PCR. A total of 308 samples from aquaculture ponds consisting of six species ...
