“…The mechanism of tolerance to WSSV is not known. It has been reported not only in Macrobrachium rosenbergii but also in crabs (Supamattaya et al 1998), Penaeus japonicus (Venegas et al 2000) and even P. monodon under some circumstances (Tsai et al 1999, Withyachumnarnkul 1999. The response of P. japonicus has been called 'quasi-immune' (Venegas et al 2000).…”

“…Other strategies with potential to combat WSSV infections include the induction of antiviral genes present in shrimp (Luo et al 2003), the application of synthetic antiviral peptides (Yi et al 2003), and the induction of a 'WSSV neutralizing factor' in shrimp using sublethal concentrations of WSSV (Venegas et al 2000, Wu et al 2002.…”

In the past, strategies to control white spot syndrome virus (WSSV) were mostly tested by infectivity trials in vivo using immersion or per os inoculation of undefined WSSV infectious doses, which complicated comparisons between experiments. In this study, the reproducibility of 3 defined doses (10, 30 and 90 shrimp infectious doses 50% endpoint [SID 50 ]) of WSSV was determined in 3 experiments using intramuscular (i.m.) or oral inoculation in specific pathogen-free (SPF) Litopenaeus vannamei. Reproducibility was determined by the time of onset of disease, cumulative mortality, and median lethal time (LT 50 ). By i.m. route, the 3 doses induced disease between 24 and 36 h post inoculation (hpi). Cumulative mortality was 100% at 84 hpi with doses of 30 and 90 SID 50 and 108 hpi with a dose of 10 SID 50 . The LT 50 of the doses 10, 30 and 90 SID 50 were 52, 51 and 49 hpi and were not significantly different (p > 0.05). Shrimp orally inoculated with 10, 30 or 90 SID 50 developed disease between 24 and 36 hpi. Cumulative mortality was 100% at 108 hpi with doses of 30 and 90 SID 50 and 120 hpi with a dose of 10 SID 50 . The LT 50 of 10, 30 and 90 SID 50 were 65, 57 and 50 hpi; these were significantly different from each other (p < 0.05). A dose of 30 SID 50 was selected as the standard for further WSSV challenges by i.m. or oral routes. These standardized inoculation procedures may be applied to other crustacea and WSSV strains in order to achieve comparable results among experiments.

“…Protection against WSSV infection appeared 3 wk after the primary infection and lasted 2 mo (Wu et al 2002). Moreover, this protection toward WSSV showed a degree of specificity (Venegas et al 2000). It is also possible to induce protection against WSSV by intramuscular (IM) injection with formalin-inactivated WSSV or with recombinant structural proteins of WSSV, rVP26 and rVP28 (Namikoshi et al 2004).…”

White spot syndrome virus (WSSV) is the causative agent of white spot disease (WSD), one of the most serious diseases affecting global shrimp farming. We compared WSSV infection induction in kuruma shrimp Marsupenaeus japonicus by oral, immersion, and intramuscular injection (IM) exposure methods and evaluated the oral vaccine prepared from the recombinant WSSV proteins rVP26 and rVP28. The 50% lethal doses (LD 50 , respectively, indicating that WSSV infection efficiency by oral challenge was significantly less than the other 2 challenge routes. However, in shrimp farms it is believed that WSSV infection is easily and commonly established by the oral route as a result of cannibalization of WSSV-infected shrimp. Kuruma shrimp vaccinated orally with WSSV rVP26 or rVP28 were challenged with WSSV by oral, immersion, and IM routes to compare protection efficacy. The relative percent survival values were 100% for oral challenge, 70 to 71% for immersion, and 34 to 61% for IM. Thus, the protection against WSSV-infection that was induced in kuruma shrimp by oral vaccination with rVP26 or rVP28 seemed equivalent to that obtained through IM vaccination.)

WSSV is pathogenic to kuruma shrimp beginning at the postlarval 10 stage (PL10) (Venegas et al. 1999). The major route of WSSV infection appeared to be through vertical transmission in kuruma shrimp hatcheries, because the occurrence of WSD in postlarvae notably decreased following selection of WSSV-free broodstock . However, horizontal transmission of WSSV, both by cannibalism and through waterborne exposure, is an infection route of concern in kuruma shrimp farms (Wu et al. 2001, Momoyama & Muroga 2005. Stable seed production of specificpathogen-free (SPF) kuruma shrimp was accomplished using countermeasures for the prevention of WSSV, such as selection of WSSV-free broodstock by PCR, disinfection of eggs with iodine, and sterilization of rearing water , Satoh et al. 2001. At shrimp farms, however, it is still difficult to prevent WSSV infection due to horizontal transmission from other crustaceans present in the farm environment and cannibalism among reared shrimp , Momoyama 2003.Recently, Venegas et al. (2000) described a 'quasiimmune response' in kuruma shrimp wherein those that naturally survived WSD were protected against subsequent WSSV challenge.
