“…Studies that address the use of chemotherapy as control for WSSV are few. However, studies with STEL water, a disinfectant, show that when used continuously for the disinfection of seawater, it may be effective for preventing WSSV infection in shrimp (Park, Seok, Cho, Baek, Lee, Kim, Kim, Chang & Park 2004).…”

White Spot Syndrome Virus in cultured shrimp: A review

Shrimp is one of the main aquaculture species in the world. Different viruses affect them, which causes serious mortality to economically important species, such as Penaeus monodon, Litopenaeus vannamei and L. stylirostris, among others. White spot syndrome virus or WSSV is a highly lethal, stress‐dependent virus, which belongs to the family Nimaviridae, genus Whispovirus. Three WSSV virus isolates were first detected in 1992 in Thailand, Taiwan and China. Later, a fourth isolate of the virus was detected in the Americas in 1999. This virus has a large circular double‐stranded DNA genome with different sizes (292.9–307.2 kb), where the diverse isolates show differences in virulence. This virus infects a wide range of aquatic crustaceans by vertical and horizontal transmission, with different mortality results. The spread of infection between regions may be due to infected shrimp and carriers such as other crustaceans, seabirds, aquatic arthropods or other vectors. The aim of this work is to describe the current knowledge on the status, transmission, pathology, isolation, control and genomic characteristics of WSSV.

“…WSSV exclusion methods include pond drying, disinfection (Chang et al, 1998;Park et al, 2004), water filtering (Lightner, 2005;Schuur, 2003), stocking specific pathogen-free [SPF] postlarvae (Lightner, 2003;Lightner and Redman, 1998) and removing vectors and/or carriers (Corsin et al, 2005;Lotz, 1997). Nonetheless the search for novel, effective products to reduce/control disease and mortality caused by WSSV is much needed.…”

“…Although the viral nucleic acid almost not be decreased, the survival rate of juveniles increased significantly into 37.03% ± 6.41% and 92.59% ± 6.41% at the concentration of 50 and 100 mg/L, respectively ( p < .05). Chlorine‐containing disinfectant could damage viral nucleic acid (Park et al., 2004; Yang et al., 2001). WSSV lost infectivity after treated with hypochlorous acid and 50 mg/L chlorine dioxide for 1 h, and no crayfish dead after immersion with disinfectant (Li et al., 2014; Xie et al., 2000).…”

Micropterus salmoides rhabdovirus (MSRV) is a significant pathogen that causes high morbidity and mortality in largemouth bass, leading to enormous economic losses for largemouth bass aquaculture in China. The aim of this study was to investigate the efficacy of four disinfectants (potassium permanganate, glutaraldehyde, trichloroisocyanuric acid and povidone iodine) on MSRV, to control the infection and transmission of MSRV in largemouth bass aquaculture. The disinfectants were tested at different concentrations (5, 25, 50, 100 and 500 mg/L) prepared with distilled water for 30 min contact time, and the viral nucleic acid was quantified using qPCR and the infectivity was tested by challenge experiment. Potassium permanganate at 5–500 mg/L, glutaraldehyde at 500 mg/L, trichloroisocyanuric acid at 50–500 mg/L and povidone iodine at 500 mg/L concentration could effectively decrease the virus nucleic acid, and the survival rate of largemouth bass juveniles after challenge experiment increased significantly from 3.7% ± 6.41% to 33.33 ± 11.11% – 100%. Moreover, the minimum effective time of 5 mg/L potassium permanganate was further studied at 2, 5, 10 and 20 min contact time. The viral nucleic acid decreased significantly at 5–20 min exposure time, and the survival rate increased significantly from 7.41% ± 6.41% to 77.78 ± 11.11% – 100%. The median lethal concentration (LC50) values of potassium permanganate were 10.64, 6.92 and 3.7 mg/L at 24, 48 and 96 h, respectively. Potassium permanganate could be used for the control of MSRV in the cultivation process; the recommended concentration is 5 mg/L and application time should be less than 24 h. The results could be applied to provide a method to control the infection and transmission of MSRV in water, and improve the health status of largemouth bass.
