CN110468069A 一种干酪乳杆菌YFI-5及其在抗鲤疱疹病毒II型中的应用 有权

一种干酪乳杆菌YFI-5及其在抗鲤疱疹病毒II型中的应用
摘要：
本发明涉及水产抗病毒微生态制剂技术领域，具体涉及一种干酪乳杆菌YFI-5及其在抗鲤疱疹病毒2型中的应用。本发明所述干酪乳杆菌的保藏编号为CCTCC NO：M2019654本发明中的干酪乳杆菌YFI-5发酵上清液，能在降低鲤疱疹病毒II型（CyHV-2）对宿主细胞的感染活性，抑制CyHV-2病毒入侵对细胞的感染。对细胞无毒副作用。饲料添加干酪乳杆菌YFI-5菌体可有效降低鲫鱼感染CyHV-2的死亡率，可以用于预防和治疗鲫造血器官坏死症。
摘要（英）：

The invention relates to the technical field of aquatic antiviral microecological preparation, and in particular, relates to lactobacillus casei YFI-5 and an application thereof in resistance of cyprinid herpesvirus 2 (CyHV-2). The lactobacillus casei has the preservation number of CCTCC NO:M2019654. A fermentation supernatant of the lactobacillus casei YFI-5 can reduce the infection activity of CyHV-2 on host cells and inhibit the infection of CyHV-2 virus invasion on the cells, and has no side effects on cells. The feed with addition of the lactobacillus casei YFI-5 can effectively reduce the mortality rate of crucian carp infected by CyHV-2, and can be used for preventing and treating crucian carp hematopoietic necrosis.
