猪链球菌-副猪嗜血杆菌二联亚单位疫苗在小鼠的免疫效力分析
Analysis of Immune Effect on Streptococcus suis-Haemophilus parasuis Bivalent Subunit Vaccine in Mice
摘要
Abstract
This study aims to develop a new kind of bivalent genetic engineering vaccine used to control Streptococcus suis (SS) disease and Haemophilus parasuis (HPS) disease, and to evaluate the vaccine's immune effect. Four proteins, Streptococcus suis serotype 2 proteins SLY, HP0197, and Haemophilus parasuis outer membrane proteins D15 and HPS06257 are selected, recombinant expressed, purified and added adjuvant of certain proportion to be made with different components of subunit vaccines. In the present study, the Streptococcus suis serotype 2-Hae-mophilus parasuis (SS2-HPS) bivalent subunit vaccine and their single vaccines could elicit a significant humoral antibody response and confer significant protection against challenge with lethal dose of SS2 or HPS in mice, respectively. In addition, the hyperimmune sera against these vaccines could efficiently kill the bacteria in the opsonized phagocytosis test and confer significant protection against SS2 infection in the experiment of passive immunization. The study shows this SS-HPS bivalent subunit vaccine has good immune protection in mice.关键词
