Abstract

The invention discloses a vaccine for preventing golden pompano ulcer, relating to a vaccine. The invention provides an application of Enterococcus faecalis in preparing medicines for preventing golden pompano ulcer, and provides a vaccine. The vaccine is prepared by using Enterococcus faecalis and pharmaceutically acceptable auxiliary materials or carrier. The vaccine provided by the invention can stimulate golden pompano to generate immunity to resist ulcer, and can effectively prevent golden pompano ulcer.

Description

technical field [0001] The invention relates to a fish vaccine, in particular to a vaccine for preventing golden pomfret canker disease. Background technique [0002] The scientific name of golden pomfret is oval pomfret, and the local name is yellow wax pomfret and golden pomfret. Golden Pomfret has the characteristics of delicious meat and rich nutrition, and is very popular among consumers. Therefore, the cultivation of golden pomfret has developed rapidly nationwide, and its cultivation scale and cultivation output have all increased year by year. [0003] But in recent years, a kind of "ulcer disease" characterized by skin ulcers on the body surface, exophthalmos, and bleeding points in the eyes has occurred in the golden pomfret breeding area in Hainan in recent years. It has the characteristics of strong infectivity and high mortality, which has brought huge economic losses to farmers. At the same time, due to the abuse of drugs, the emergence of drug resistance ha...
