This study addresses a mechanism for inducing systemic immunity to Shiga-like toxins by oral administration of a Shiga-like toxin I B-subunit-expressing Vibrio cholerae vaccine strain [CVD 103-HgR(pDA60)]. Two sets of three rabbits were given either CVD 103-HgR or CVD 103-HgR(pDA60) orally. All rabbits immunized with CVD 103-HgR(pDA60) developed neutralizing serum antibodies to Shiga-like toxin I. None of the controls developed such antibodies.
本研究探讨了通过口服表达志贺样毒素I B亚基的霍乱弧菌疫苗株[CVD 103-HgR(pDA60)]诱导针对志贺样毒素的全身免疫的机制。将两组各三只兔子分别口服给予CVD 103-HgR或CVD 103-HgR(pDA60)。所有用CVD 103-HgR(pDA60)免疫的兔子都产生了针对志贺样毒素I的中和血清抗体。对照组兔子均未产生此类抗体。
