Efficacy of Natural Herbal Formulation against Acute Hepatopancreatic Necrosis Disease (AHPND) causing Vibrio parahaemolyticus in Penaeus vannamei
Journal Title: Veterinary Medicine – Open Journal - Year 2017, Vol 2, Issue 1
Abstract
A formulation was developed using combination of blended natural essential oils as an anti-Vibrio parahemolyticus causing acute hepatopancreatic necrosis disease (AHPND) candidate. Lavandula latifolia, Pinus sylvestris, Jasminum officinale, Citrus limon, Prunus avium, Viola odorata, Gardenia jasminoides, Cocos nucifera, Rosa damascene and Eucalyptus globulus, mixed together to develop as anti-V. parahemolyticus product. The treatment group was fed on essential oil mixed feed whereas control group were fed on the regular feed throughout the experiment. The shrimp of both treatment and control were challenged by immersion method at day 8. The cumulative AHPND-gross sign appearance in positive control reached up to 95% at dpi 10 whereas no gross sign appeared in treatment and in negative control. The cumulative mortality reached up to 46.7% at dpi 10 in positive controls whereas no mortality recorded in treatment and in negative control. The V. parahaemolyticus isolated from the hepatopancreas of infected shrimp matched 100% with the existing AHPND strain. The trial results show that the developed natural herbal formulation has significant effect against AHPND in a controlled condition.
