Authors studied the disappearance of mothers measles antibodies among 286 babies from Ivory Coast 250 of which were living in Adzopé, a town with 30,000 inhabitants at 100 km up North from Abidjan and the 36 other babies in Abidjan. The study of antibodies by IHA showed a higher serum incidence rate of mother antibodies among 4 months aged babies in Abidjan. The more sensitive study of antibodies by the Mann serum neutralisation, shows that when 6 months aged, 60% babies from Adzope still have antibodies and when 10 months aged, none of the babies is positive. Serum negativation is late compared to Brazzaville when antibodies level is lower.
作者研究了来自科特迪瓦的286名婴儿体内母亲麻疹抗体的消失情况,其中250名婴儿生活在阿佐佩,阿佐佩是一个距阿比让以北100公里、有3万居民的城镇,另外36名婴儿在阿比让。通过间接血凝试验(IHA)对抗体进行研究表明,在阿比让4个月大的婴儿中,母亲抗体的血清发生率更高。通过曼氏血清中和试验对抗体进行的更敏感研究表明,6个月大时,来自阿佐佩的60%的婴儿仍有抗体,10个月大时,没有婴儿呈阳性。与布拉柴维尔相比,当抗体水平较低时,血清转阴较晚。
