摘要
旨在筛选适宜于猪丹毒丝菌灭活疫苗的佐剂。以分离鉴定出的猪丹毒丝菌1a型HG-1株灭活菌体为抗原分别配制矿物油佐剂疫苗(简称矿物油疫苗)、氢氧化铝胶佐剂疫苗(简称铝胶疫苗)、ISA201双相油乳佐剂疫苗(简称ISA201疫苗)、GEL02水溶性聚合物佐剂疫苗(简称GEL疫苗)、IMS1313水溶性纳米佐剂疫苗(简称IMS1313疫苗)共5种佐剂的灭活疫苗。小鼠免疫保护试验结果表明,二免14 d后使用约为4 LD50的HG-1株对小鼠进行腹腔攻毒,矿物油疫苗和GEL疫苗的保护率分别为100%(7/7)和71%(5/7),其他三种佐剂疫苗的保护率均为14%(1/7)。本研究进一步选择铝胶疫苗和GEL疫苗进行猪体对比试验;仔猪安全性试验结果表明,两种佐剂疫苗的副反应均较小;免疫保护试验结果表明,两次免疫后使用约为16 LD100的HG-1株对免疫仔猪进行耳缘静脉攻毒,两种佐剂疫苗的保护率分别为60%(3/5)和100%(5/5)。本研究最终选择GEL佐剂作为开发猪丹毒灭活疫苗的最适佐剂。
The objective of this study was to screen the adjuvant suitable for an inactivated vaccine against Erysipelothrix rhusiopathiae.The five inactivated vaccines of mineral oil adjuvant(referred as oil vaccine),aluminum hydroxide adjuvant(referred as alh vaccine),ISA201 dual phase oil emulsion adjuvant(referred as ISA201vaccine),GEL02 water-soluble polymer adjuvant(referred as GEL vaccine),and IMS1313 water-soluble nano-sized adjuvant(referred as IMS1313 vaccine)were prepared,which the antigens of that were all inactivated bacteria of E.rhusiopathiae strain HG-1,isolated and identified as serovar 1a.The immunoprotection test results of the mouse showed that after 14 days of second immunization,mice were intraperitoneally challenged with 4LD50 HG-1 solution,giving the protection rates of the five vaccines 100%(7/7),14%(1/7),14%(1/7),71%(5/7)and 14%(1/7),respectively.According to the above test results,the safety test of piglets was carried out by using alh vaccine and GEL vaccine,and the results showed that the side effects of the two adjuvant vaccines were small.Fourteen days after the second immunization,groups of pigs vaccinated with alh vaccine and GEL vaccine were challenged intravenously with 16 LD100 of HG-1 solution,and the results showed that alh vaccine and GEL vaccine provide 60%(3/5)and 100%(5/5)protective efficacy,respectively.This study identified GEL adjuvant as the optimal adjuvant for the development of an inactivated vaccine against swine erysipelas.
