目的分析羊口蹄疫灭活疫苗(inactivated food and mouth disease vaccine,IFMDV)分别与小反刍兽疫活疫苗(live attenuated peste des petits ruminants vaccine,LPPRV)及布氏菌活疫苗(live Brucella vaccine,LBV)联合使用的免疫效果。...目的分析羊口蹄疫灭活疫苗(inactivated food and mouth disease vaccine,IFMDV)分别与小反刍兽疫活疫苗(live attenuated peste des petits ruminants vaccine,LPPRV)及布氏菌活疫苗(live Brucella vaccine,LBV)联合使用的免疫效果。方法应用口蹄疫O型、亚洲1型二价灭活疫苗与LPPRV联合免疫山羊,观察山羊不良反应,采用病毒中和试验法和液相阻断ELISA法分别测定山羊血清中小反刍兽疫抗体及口蹄疫抗体水平。应用口蹄疫O型、A型、亚洲1型三价灭活疫苗与LBV(M5株)联合免疫绵羊,观察绵羊的不良反应,采用试管凝集试验及液相阻断ELISA法检测绵羊血清中布氏菌抗体及口蹄疫抗体水平。结果 IFMDV分别与LPPRV及LBV联合免疫山羊及绵羊,均未见明显的不良反应,仅出现一过性体温升高现象;IFMDV(肌肉)和LPPRV(皮下)同时联合免疫,山羊血清中小反刍兽疫抗体水平明显高于单独免疫LPPRV组(P<0.05);IFMDV与LBV联合免疫,绵羊血清中布氏菌抗体水平高于单独免疫LBV组(P<0.05),且联合免疫组抗体阳性率达100%,比单独免疫LBV组提高了13%。结论 IFMDV分别与LPPRV、LBV联合使用具有良好的安全性,且可提高LPPRV及LBV的免疫效果。展开更多

Among the different Brucella species, Brucella melitensis is considered the most virulent and is the predominant species associated with outbreaks in China. To date, no safe human vaccine is available against Brucella infection. The currently used live vaccines against Brucella in livestock induce antibodies that interfere with the diagnosis of field infection in vaccinated ani- mals, which is harmful to eradication programs. However, there is as yet no complete profile of immunogenic proteins of B. melitensis. Towards the development of a safer, equally efficacious, and field infection-distinguishable vaccine, we used immunoproteomics to identify novel candidate immunogenic proteins from B. melitensis M5. Eighty-eight immunoreactive protein spots from B. melitensis M5 were identified by Western blotting and were assigned to sixty-one proteins by mass spectrometry, including many new immunoreactive proteins such as elongation factor G, FOFI ATP synthase subunit beta, and OMPI. These provide many candidate immunoreactive proteins for vaccine development.展开更多
