China

Research—Covert Mortality Disease

 

From Abstract: A disease known as covert mortality disease has become an increasing problem in the shrimp farming industry in recent years in China and several countries of Southeast Asia, leading to serious losses in production. Penaeus vannamei (Pacific white shrimp) is affected by this disease that leads to a range of clinical symptoms including hepatopancreas atrophy and necrosis, soft shell, slow growth, and abdominal muscle whitening and necrosis in the acute stage of disease.  A new nodavirus, termed covert mortality nodavirus (CMNV), has been shown to be the etiological agent.

 

In this study, researchers report a sensitive and specific real-time reverse transcription loop-mediated isothermal amplification (RT-LAMP) assay for the rapid and quantitative detection of CMNV, a new tool for the field detection and quantification of CMNV in the diagnosis and surveillance of covert mortality disease.
