Taura Syndrome Virus

Also known as: TSV

Taura Syndrome Virus (TSV) is a highly infectious virus that affects penaeid shrimp, particularly the Pacific white shrimp (Litopenaeus vannamei). It is a member of the Dicistroviridae family. The disease is characterized by high mortality in juvenile shrimp and is often associated with poor pond management or stressful environmental conditions. Clinical signs include reddish discoloration, expanded chromatophores, soft shells, and high mortalities shortly after molting. Survivors may become carriers.

Distribution: Widespread in shrimp farming regions including the Americas and Southeast Asia
Hosts: Penaeid shrimp, primarily Litopenaeus vannamei
Detection Methods: PCR – unspecified; histological analysis
Target Tissue: Cuticular epithelium and connective tissue
