Sediment and water can act as reservoirs for White spot syndrome virus in shrimp farming
Abstract
Natural viral reservoirs such as water and sediment, in addition to other aquatic organisms may represent an extra route of transmission of the white spot syndrome virus (WSSV). The aim of the present work was to verify the presence of WSSV DNA in the sediment and water in ponds of the white shrimp Litopenaeus vannamei. DNA from sediment and water samples were obtained from four ponds in the same shrimp farm. The presence of viral DNA was tested by nested PCR with WSSV-specific primers. The data revealed the presence of WSSV DNA in the sediment and water samples from two different ponds. The results demonstrate that WSSV can be present in the sediment and water of shrimp farms, acting as important reservoirs for the dissemination of this pathogen. Sanitary measures and prophylaxis should be efficiently employed to avoid future cases of the disease. Monitoring the presence of WSSV in the water and soil of breeding sites can represent an important tool for assessing the potential of viral infection.
