White Spot Virus Detection Kit


Viral Diseases in Shrimp Production

Viral diseases in shrimp farming cause mortality and economic losses estimated in millions of dollars. These viral diseases are particularly difficult to control and prophylaxis (preventive measures) remains the most reliable way to control losses. Another alternative is the early harvesting of the production when a disease is detected in a pond. This solution allows to market smaller shrimps, but to limit the diffusion of the disease in the farm.

White Spot Virus Syndrom (WSSV) and Infectious Hypodermal and Hematopoietic Necrosis Virus (IHHNV) are important viral diseases because of their significant impact on shrimp production. White Spot Virus is observed in many species of shrimp and crabs from various geographical areas and can cause up to 100 % mortality with devastating economic impact. IHHNV is one of the most serious viral diseases of farmed shrimp. This virus is widespread in many countries and has a wide host range, which has contributed to its dissemination in many species of cultured shrimp.

For these reasons, it is necessary to have a good knowledge of the health status of shrimp farms in order to optimize production

The White Spot Virus Kit : Multiple Detection and Ease of Use

The White Spot Virus Detection Kit allows a simultaneous, easy and fast detection of both viruses using PCR.

The PCR uses a set of primers that amplify DNA fragments specific to the viruses sought. Visualization of the amplified products is achieved by specific hybridization with homologous probes deposited at predefined positions on ready-to-use membranes (mini-array).

The White Spot Virus kit has many advantages :

  • The interpretation of the results on the membrane (mini-array) can be done with the naked eye thanks to a colorimetric revelation on the nylon membrane
  • Only one step is necessary for a multiple detection
  • The result is fast (4 to 5 hours) and easy to use
  • The test has a high sensitivity and specificity.


Diag4zoo thus proposes an ideal method to detect low level or early infections, in order to limit the risks of horizontal and vertical transmissions.
