“…Supplementing diets with five herbs at 0.02%, 0.04%, and 0.08 % resulted in better survival rate and reduction on viral load, in black tiger prawns (Citarasu et al, 2006), and helped to decrease Vibrio load in black tiger prawn post-larvae (PL) after bath challenging Vibrio harveyi (Velmurugana et al, 2010). Among equal proportions of five plant extracts mixed with the diet at concentrations of 0.01%, 0.02%, 0.04%, and 0.08%, the 0.04% diet was the most effective in the survival, growth, and immune responses of Epinephalus tauvina (Punitha et al, 2008).…”

“…Herbal extracts enhanced the immune responses of grouper Epinephalus tauvina against the pathogen V. harveyi (Punitha et al, 2008). Diets with five herbal extracts decreased the Vibrio load in black tiger prawn PL after bath challenging V. harveyi (Velmurugana et al, 2010). The dietary supplementation of Lactuca indica extract increased disease resistance in kelp grouper against Streptococcus iniae infection (Harikrishnan et al, 2011c).…”

“…There has been a number of studies reported antibacterial effects of medicinal plants on V. parahaemolyticus and V. harveyi [7,[23][24][25][26][27][28][29], but our study represents the second attempt to investigate plant effects on AHPND pathogenic bacteria, followed one report in 2014 [30]. In addition, it is the first time that plants were tested against the AHPND pathogenic bacterium that was different from V. parahaemolyticus and was closet to V. harveyi and the V. harveyi KC13.17.5 strain.…”

Objectives: The objectives are aimed to investigate the antibacterial properties of five Vietnamese medicinal plants against acute hepatopancreatic necrosis disease (AHPND)-caused bacterial pathogens, to verify their potentials to apply as a new treatment therapy. Methods:Extracts from plants, such as Psidium guajava leaf, Piper betle L. leaf, Phyllanthus amarus leaf, Rhodomyrtus tomentosa seed, and Allium sativum bulb, were tested against three AHPND-caused bacteria. Agar infusion and broth dilution methods were employed to evaluate extract in vitro antibacterial effects, while experiments with cultured whiteleg shrimps were applied to access their safety when applied in vivo. High-performance liquid chromatography (HPLC) analysis was applied to identify components in the extracts.Results: P. amanus and R. tomentosa extracts exerted the strongest inhibition on tested bacteria. Other extracts, including P. betel and P. guajava, were less effective, while A. sativum showed no effects against bacteria. In safety assessment experiments, we observed that only crude extracts of R. tomentosa and A. satium were safe, while others significantly reduced their survival rates. HPLC showed that extracts of high antibacterial properties had rich phenol constituents. In addition, the phenolic profile of R. tomentosa showed the presence of piceatannol. Conclusion:Considering both of antibacterial effects and safety properties altogether, we concluded that among the five examined plant materials of this study, R. tomentosa had the highest potential to apply in AHPND treatment, as only this plant showed the high effects on pathogenic bacteria while were still safe for host aquatic shrimps.

“…The e cacy of U. fasciata incorporated diet was also proved in controlling shrimp bacterial pathogens such as V. scheri, V. alginolyticus, and V. harveyi during the infection on P.monodon postlarvae (Selvin et al 2011). Several herbal plant diets were fed to P. monodon postlarvae and tested against V. harveyi, the results showed 75% improvement in survival (Velmurugan et al 2010). Also, the reduced mortalities on P. monodon postlarvae tested against V. harveyi was observed during the oral administration of fucoidan compound isolated from brown algae Undaria pinnati da through feed (Traifalgar et al 2009).…”

Molecular docking study of bio-inhibitors extracted from marine macro-alga Ulva fasciata against hemolysin protein of luminescence disease-causing Vibrio harveyi

Shrimp grow-out and hatchery systems are being affected by bacterial disease particularly Vibrios. The use of chemotherapeutic agents in aquaculture practices has to lead to the development of resistance among aquatic bacteria. Thus, health management becomes of major importance in aquaculture. Under this situation, progressing bio-inhibitors from marine resources are most appropriate to be considered against pathogenic bacteria. Molecular docking is an appropriate tool in structural biology and computer-assisted drug design to predict and neutralize a target protein of known diseases. In this study, marine macroalga Ulva fasciata was aimed at developing inhibitors against luminescence disease-causing pathogenic bacteria Vibrio harveyi. U. fasciata was collected from the intertidal zone of Thoothukudi, Tamil Nadu, India. Extract of U. fasciata was tested against growth and virulence factors of V. harveyi during Penaeus monodon larviculture. For molecular docking, the homology modeling of virulence of hemolysin protein of V. harveyi was designed and used for docking studies against the compounds of U. fasciata as identi ed by GC-MS analysis. Extract of U. fasciata@200 mg mL -1 had exhibited reductions on Cumulative Percentage of Mortality (32.40%) in postlarvae against the challenge of V. harveyi infection. In docking analysis, the bio-inhibitor Methyl dehydroabietate showed the highest binding a nity among compounds docked. Statistical analysis had revealed signi cant differences (p<0.05) in trials.Therefore, it was proved that the bio-inhibitors from U. fasciata will be a better option for controlling luminescence disease-causing V. harveyi in shrimp growout practices.
