Infectious myonecrosis virus (IMNV) is one of the most pathogenic viruses causing severe mortality in Penaeus vannamei in many countries. Several strategies have been implemented to inhibit the presence of IMNV disease. The present study was carried out to examine the antiviral activity of Cynodon dactylon ethanolic extract on IMNV disease in shrimp by in vivo testing. The C. dactylon plant extract was incorporated with artificial pellet feed at a concentration of 10, 15%, 20%, and 25%. For the experimental challenge shrimp were fed with IMNV-infected shrimp meat. The antiviral activity was determined by observing survival rates, and IMNV infection was confirmed at the end of the experiment through polymerase chain reaction (PCR) identification. This study showed that the plant extract of C. dactylon was found to be highly effective in preventing IMNV infection with up to 98% survival rate in Penaeus vannamei .

犬齿龙对南美白对虾传染性肌坏死病毒（IMNV）功效的研究

传染性肌坏死病毒（IMNV）是在许多国家引起南美白对虾严重死亡的最具致病性的病毒之一。已经实施了几种抑制IMNV疾病的策略。本研究旨在通过体内测试来检查犬牙实齿乙醇提取物对虾IMNV疾病的抗病毒活性。仙人掌果植物提取物与人造颗粒饲料的浓度分别为10％，15％，20％和25％。对于实验性挑战，将受IMNV感染的虾肉喂给虾。通过观察存活率确定抗病毒活性，并在实验结束时通过聚合酶链反应（PCR）鉴定确认IMNV感染。这项研究表明，C。的植物提取物。
