Growth of Rocky Mountain spotted fever (RMSF) rickettsiae in duck embryo cell (DEC) cultures and chicken embryo cell (CEC) cultures was evaluated. Experimental lots of duck embryo cell- and chicken embryo cell-grown Rocky Mountain spotted fever vaccines and a commercial lot of yolk sac-grown vaccine were compared for protective efficacy in rhesus monkeys. Incidence and magnitude of antibody response, febrile response, and rickettsemia, as well as incidence of fatalities, suggested that both cell culture-derived vaccines were more immunogenic than the yolk sac-grown vaccine.
对落基山斑疹热立克次体在鸭胚细胞(DEC)培养物和鸡胚细胞(CEC)培养物中的生长情况进行了评估。比较了实验批次的鸭胚细胞培养和鸡胚细胞培养的落基山斑疹热疫苗以及一批商业卵黄囊培养疫苗在恒河猴中的保护效力。抗体反应的发生率和强度、发热反应、立克次体血症以及死亡率表明,两种细胞培养衍生疫苗比卵黄囊培养疫苗更具免疫原性。
