Abstract ▼ AI-Helper

This study investigated the disinfection effect of monopersulfate (MPS) compound against white spot syndrome virus (WSSV) by bioassay using kuruma shrimp (Marsupenaeus japonicas). A WSSV stock was prepared with muscle homogenate from WSSV-infected whiteleg shrimp (Penaeus vannamei) and its lethal dose 50% endpoint (LD50) and infectious dose 50% endpoint (SID50) were respectively determined as 10-5.63 and 10-6.79 in bioassay using kuruma shrimp, followed by PCR assays. The disinfective effect of MPS compound (1.2 ppm, 2.4 ppm, 4.8 ppm) was performed by bioassay using about 10-fold higher dilution (10-4) of WSSV homogenate. The compound resulted in WSSV inactivation by a concentration-dependent manner. In addition, 4.8 ppm of MPS completely prohibited WSSV infection. To our knowledge, this study is the first report about the usefulness of MPS as a disinfectant to WSSV.

문제 정의

However, there is no information about the disinfection effect of MPS to WSSV. In this study, we examined the disinfective effect of MPS-based product to WSSV by bioassay using kuruma shrimp (Marsupenaeus japonicas).
