Detection and Genetic Characterization of <i>Enterocytozoon hepatopenaei</i> in Giant Freshwater Prawn (<i>Macrobrachium rosenbergii</i>) Imported into South Korea.

ABSTRACT: This study investigated Macrobrachium rosenbergii imported from India (15 batches, N = 180) and Vietnam (7 batches, N = 84) between 2023 and 2024, for Enterocytozoon hepatopenaei (EHP) monitoring and genetic analysis. Polymerase chain reaction assays detected EHP in 13.3% (2/15) and 71.4% (5/7) samples from India and Vietnam, respectively. The sequence of the small subunit ribosomal ribonucleic acid region of the EHPs isolated from M. rosenbergii showed no significant differences from those available in GenBank. Interestingly, spore wall protein (SWP) 1 region analysis revealed that M. rosenbergii EHPs could be divided into three groups, some of which were closely related to Penaeus vannamei EHPs. Similarly, the internal transcribed spacer-1
