Abstract

Using a lactoferrin latex agglutination assay, we have compared the inflammatory responses to a cholera vaccine candidate, CVD 110, in which all known toxin genes have been deleted or mutated yet still produced significant diarrhea, with a less reactive vaccine strain and wild-type El Tor and 0139 Vibrio cholerae strains. Data suggest that diarrhea due to attenuated and wild-type El Tor V. cholerae, and to a lesser extent 0139 V. cholerae, involves an inflammatory response. Further study is required to further elucidate the mechanism of the process(es) involved.

摘要

我们使用乳铁蛋白乳胶凝集试验,比较了一种霍乱疫苗候选株CVD 110、反应较弱的疫苗株、野生型埃尔托霍乱弧菌和0139霍乱弧菌菌株的炎症反应。CVD 110中所有已知的毒素基因均已缺失或突变,但仍会引起明显腹泻。数据表明,减毒和野生型埃尔托霍乱弧菌引起的腹泻,以及程度较轻的0139霍乱弧菌引起的腹泻,都涉及炎症反应。需要进一步研究以进一步阐明其中涉及的过程机制。
