Infectious hypodermal and hematopoietic necrosis virus (IHHNV) causes mortality or runt deformity syndrome in penaeid shrimps and is responsible for significant economic losses in the shrimp aquaculture industry. Here, we describe a novel real-time isothermal recombinase polymerase amplification (RPA) assay developed for IHHNV detection. Using IHHNV plasmid standards and DNA samples from a variety of organisms, we evaluated the ability of the IHHNV-RPA assay to detect IHHNV based on analysis of its sensitivity, specificity, rapidity, and reproducibility. Probit analysis of eight independent experimental replicates indicated satisfactory performance of the RPA assay, which is sufficiently sensitive to detect as few as 4 copies of the IHHNV genome within 7 min at 39 °C with 95 % reliability. Therefore, this rapid RPA method has great potential for applications, either in field use or as a point of care diagnostic technique.
