Abstract

To isolate novel cellular factors that are activated or repressed upon WSV infection, the RNA fingerprints of healthy and WSV infected blue shrimp ( Penaeus stylirostris ) were compared using the mRNA differential display technique. Thirty-two unique differentially expressed, and one constitutively expressed, cDNA sequences were retrieved. Six of 32 cDNAs showed similarities with the database entries: cDNA 10G32-142 to a shrimp arginine kinase, 22C48-201 to shrimp mitochondrial ATPase gene; 22C47-197, 21G49-203 and 20A55-268 to shrimp ESTs and 20G50-206 to a WSV gene, ORF 116. The constitutively expressed gene showed significant similarity to a yeast elongation factor 1-alpha gene. The expression of a subset of differentially expressed genes (13 of 32) was further evaluated by real-time RT-PCR. Ten of 13 genes showed statistically significant changes in expression between healthy and WSV infected animals suggesting that these genes may play an important role in WSV pathogenesis.
