在两周的时间里,豚鼠组接受了四次来自铜绿假单胞菌的脂多糖疫苗、来自大肠杆菌O 111的J-5突变体的交叉保护核心糖脂疫苗或盐水的肌内注射。血清中疫苗抗原的被动血凝抗体滴度通常增加四倍或更多。然后诱导实验性出血性假单胞菌肺炎,其中接受生理盐水的动物的存活率为15%,接受假单胞菌疫苗的动物的存活率为81%(P< 0.001),而接受J-5疫苗的动物的存活率为42%。因此,在J-5疫苗的接受者中仅检测到针对假单胞菌肺炎的弱交叉保护。进一步的研究表明,E对肺炎没有保护作用。大肠杆菌或克雷伯氏菌动物接受J-5疫苗。从这些数据来看,种特异性疫苗接种似乎上级于交叉保护性抗原疫苗接种以对抗实验性假单胞菌肺炎。
Groups of guinea pigs received four injections intramuscularly of lipopolysaccharide vaccine derived fromPseudomonas aeruginosa, cross-protective core glycolipid vaccine derived from the J-5 mutant ofEscherichia coliO111, or salineduring a two-week period. Titers of passive hemagglutinating antibody to vaccine antigens in serum routinely increased fourfold or more. Experimental hemorrhagic pseudomonas pneumonia was then induced, from which the rates of survival were 15% among animals receiving saline, 81% among animals receiving pseudomonas vaccine(P< 0.001), and 42% among animals receiving J-5 vaccine. Thus, only weak cross-protection against pseudomonas pneumonia was detected in the recipients of J-5 vaccine. Further studies revealed no protection against pneumonia due to eitherE. coliorKlebsiellain animals receiving J-5 vaccine. From these data, species-specific vaccination appears to be superior to vaccination with cross-protective antigen against experimental pseudomonas pneumonia.
