IQ2000™ IMNV Detection and Prevention System
Introduction
Infectious Myonecrosis Virus (IMNV) had its first appearance in the State of Piaui, Brazil, in September, 2002. And it is not until February, 2004, that Dr. Donald V. Lightner, from the University of Arizona, US, officially confirmed the discovery of the new virus. The late discovery and the lack of information about the pathology caused severe damages to the Brazilian shrimp farming industry. In 2003, loss in production was estimated about $20 million USD in crops of L. vannamei, an unexpected impact for the sector.
The “Zombie Virus”, a nickname given by farmers, is still of an unknown origin. The virus presents RNA genome and belongs to the Totiviridae family. The typical symptoms are necrosis of abdomen and cephalothorax, loss volume of hepatopancreas, loss of transparency and coloration around the tail, an appearance of cooked shrimp, etc. Mortality can occur throughout all cycles of shrimp’s life, and its rate increases when the shrimp is over 6 g, which matches the phase of high consumption of food ration, causing great loss in resources and feed.
GeneReach has launched a highly accurate detection system for IMNV, a new product in IQ2000™ viral detection series. It has inherited all the same features from IQ2000™ series, such as internal control and semi-quantitative design. The first design eliminates false negative possibilities, and the second one measures the degree of infection.
