From Abstract (Click on the link in the Source below for a free, full copy of the paper.)


After AHPND was characterized, a major focus of the AHPND control strategy was to monitor broodstock shrimp and post larvae for freedom from AHPND by nucleic acid amplification methods, most of which required use of expensive and sophisticated equipment not readily available in a shrimp farm setting.  In this study, researchers describe a simpler but equally sensitive approach for detection of AHPND based on loop-mediated isothermal amplification (LAMP) combined with unaided visual reading of positive amplification products using a DNA-functionalized, ssDNA-labled nanogold probe (AuNP).
