We developed a qPCR assay based on the β-tubulin gene sequence for the shrimp microsporidian parasite Enterocytozoon hepatopenaei (EHP). This assay reacted with the hepatopancreas (HP) of EHP-infected shrimps, and the highest copy numbers were found in HP and feces samples from Southeast Asian countries (106–108 copies mg−1), while HP samples from Latin America, Artemia, and EHP-contaminated water showed lower amounts (101–103 copies mg−1 or mL−1 of water). No false positive was found with the normal shrimp genome, live feeds, or other parasitic diseases. This tool will facilitate the management of EHP infection in shrimp farms.
