SWINE ERYSIPELAS KILLED VACCINE PREPARED WITH INACTIVATED BACTERIAL CULTURE AND PROTECTIVE PROTEIN ANTIGEN OF E. RHUSIOPATHIAE

摘要

A swine erysipelas inactivated vaccine is provided to significantly improve the immune capacity by adding a protein antigen obtained from a culture supernatant to a swine erysipelas inactivated antigen. The swine erysipelas inactivated vaccine is prepared by the method comprising the steps of: (a) after inoculating swine erysipelas seed into a swine erysipelas producing culture medium, culturing it at a temperature of 37 deg.C for 18-20 hours and adding formaline thereto to inactivate it, centrifuging it with the speed of 6,000 rpm for 30 minutes and collecting supernatant after removing settled down bacteria therefrom; (b) gradually adding ammonium sulfate to the supernatant until the solution being saturated to separate protein therefrom; (c) after putting the protein obtained from the step (b) in a dialysis membrane to remove impurities therefrom and obtain purified protein; (d) floating the purified protein in PBS(pH of 7.2) to prepare a swine erysipelas specific antigen; and (e) adding the swine erysipelas specific antigen to a swine erysipelas inactivated antigen to have 10-50% of the swine erysipelas specific antigen therein and mixing it. The swine erysipelas inactivated vaccine further comprises an immunostimulant.
