“…Our results also showed a higher survival rate (83.3%) of the treatment group (fed with 4% galangal extract) than the control group (feeding with 0% extract). The results revealed the efficiency of the extract, which has ability to inhibit V. parahaemolyticus (EMS/AHPND), and it may stimulate the immune system in the tested shrimp (Chaweepack et al, 2015). Therefore, shrimp fed galangal extract diet are healthier than the control group, and shrimp fed a galangal extract diet could resist infection well.…”

White feces syndrome and acute hepatopancreatic necrosis disease (AHPND) are serious diseases that have recently been noted in Pacific white shrimp (Litopenaeus vannamei). Vibrio bacteria and 6 species of fungi (Aspergillus flavus, A. ochraceus, A. japonicus, Penicillium sp., Fusarium sp., and Cladosporium cladosporioides) were isolated from shrimp naturally infected with white feces syndrome. Antibiotics have been used to treatment the disease for many years, but these have been ineffective and have resulted in drug residue problems for the shrimp industry. In this study, an alternative method was tested for its efficacy in controlling these pathogens. The crude extract of galangal (Alpinia galanga Linn.), an herbal medicine, inhibited the growth of 8 vibrio species of the pathogen, V. parahaemolyticus (EMS/AHPND) in particular. The results also showed that 0.5 mg/ml of the galangal extract was a concentration that produced the strongest inhibition of the fungi A. ochraceus. Naturally infested shrimp L. vannamei were fed 2 and 4% (v/w) portions of the herb extract for 12 days and their progress was compared with that of a control group (no herb extract). At the end of the feeding trial, the numbers of total Vibrio spp. and the incidence of fungi infestation in the hepatopancreas and intestines of treated shrimp were significantly lower than that in the control group (P<0.05). Furthermore, the survival rates for the treatment groups, after injections with V. parahaemolyticus (EMS/AHPND), were significantly higher than that of the control group (P<0.05). Based on these results, we can report that the galangal extract has antimicrobial properties that are applicable as bio-medicinal agents against white feces syndrome and AHPND. Therefore, in the future this herb should be an alternative to chemotherapeutic agents that are being used in the shrimp industry.

Efficacy of Rose Myrtle Rhodomyrtus tomentosa Seed Extract against Acute Hepatopancreatic Necrosis Disease in Pacific Whiteleg Shrimp Penaeus vannamei

et al. 2019

View full text Add to dashboard Cite

Acute hepatopancreatic necrosis disease (AHPND) is a new emerging bacterial disease that has been recently reported to cause mass mortalities in Pacific whiteleg shrimp Penaeus vannamei. Antibiotics have been used to treat bacterial diseases in shrimp, but most of them have been ineffective and have resulted in drug residues in the harvested shrimp products. In this study, an alternative approach was tested for its efficacy in controlling AHPND. The extract of rose myrtle Rhodomyrtus tomentosa seed, a traditional Vietnamese medicine, was tested for antibacterial effect against three AHPND bacterial strains in vitro (Vibrio parahaemolyticus [VPAHPND] KC12.020, VPAHPND KC13.14.2, and V. harveyi KC13.17.5) and was further evaluated for its potential efficacy in prevention of AHPND in shrimp in vivo. The in vitro studies showed that the antibacterial activity of the R. tomentosa extract was dose dependent, with the strongest bacterial susceptibility (≥18.0 mm) at a concentration of around 3,500 μg/disc. The in vivo studies showed that after challenge with VPAHPND KC12.020, the survival rates for shrimp in the groups that received feed pellets supplemented with extract at 3.5% or 7.0% (survival ~48.9% and 52.2%, respectively) were significantly higher than the zero survival rate in the positive control group, which received feed without the extract. These results indicate that the use of the R. tomentosa extract as an alternative therapy for control of AHPND in shrimp could help to minimize disease outbreaks. As a result, the extract is further expected to reduce drug/chemical residues in shrimp products.
