A few days ago, Zhou Yong, Yangtze River Fisheries Research Institute, Chinese Academy of Fishery Sciences, etc. applied for”a lactic acid bacteria compound inoculum and its anti-carp herpes virus type II”Application” is authorized by the national invention patent, the patent number is:ZL201910763700.9.
This invention discloses a lactic acid bacteria compound inoculum and its application in anti-carp herpes virus type II. The compound bacterial agent involved in the invention is formed by mixing or fermenting Lactobacillus casei, Lactobacillus plantarum, and Lactobacillus casei with the preservation number of CCTCC NO:M2019654. The fermentation supernatant of the compound bacterial agent in the invention can reduce the infection activity of CyHV-2 (CyHV-2) to host cells, inhibit the infection of cells caused by CyHV-2 virus invasion, and has no toxic side effects on cells, and compound bacteria The inhibitory effect of the agent is better than that of using Lactobacillus casei YFI-5 alone. The addition of compound bacteria in feed can effectively reduce the mortality of crucian carp infected with CyHV-2, and can be used to prevent and treat crucian carp hematopoietic organ necrosis.
