For this study, fve treatments were tested: uninfected shrimp fed with pelleted feed (T ), WSSV-infected shrimp fed with pelleted feed C (T ), infected shrimp fed with pelleted feed with 1% ethanol extract of U. tomentosa (EEUT) (T ), 1 2 infected shrimp fed with pelleted feed with 2% EEUT (T ), and infected shrimp fed pelleted feed 3 with 4% EEUT (T ). The chemical analysis of EEUT showed the presence of alkaloids, favonoids, 4 sterols, terpenes, coumarins, and tannins and also a high in vitro free radical-scavenging activity as well as high total phenolic content. Shrimp fed with 2 and 4% EEUT (T and T ) showed a survival 3 4 probability signifcantly higher than T and T treatments and no clinical symptoms ofWSSV infection. 1 2 Immunological assay also showed a positive phenoloxidase activity effect on shrimp fed with EEUT. aLitopenaeus vannamei aplant extracts aUncaria tomentosa awhite spot syndrome virus1 aKUHN, F.1 aPADILHA, P.
