Innate Immune Response of NNV Infection in Fish and Its Disease Prevention

The innate immune response which is seen as the initial defense mechanism induced upon foreign invasion has been well documented in higher vertebrates. This has also been observed in fish infected with NNV. However, the fish immune system based on fully established genome project has not been fully elucidated. Therefore, in this review, we hope to correlate NNV infection in fish that has devastated the aquaculture industry, to its host immune system. Further, we discuss the potential preventive measures in overcoming the widespread of this neurodisease.
