The authors report the results of blood group determinations in a 9-year-old girl in whom two populations of erythrocytes were discovered. The larger population accounting for nearly 80% of erythrocytes contained the antigen A2, the smaller population had the B antigen. Besides that differences were observed in the antigens of Duffy and Lewis systems. In the saliva A and H antigens were revealed. Familial investigations indicated the participation of two gametes of maternal origin (mother--AB, father--O) although no evidence of twin pregnancy was available. The cause of this chimaerism has not been explained.
作者报告了一名9岁女孩血型测定的结果，该女孩体内发现了两种红细胞群体。占红细胞近80%的较大群体含有A2抗原，较小群体含有B抗原。此外，还观察到达菲和刘易斯系统抗原存在差异。在唾液中发现了A和H抗原。家族调查表明有两个母系来源的配子参与其中（母亲为AB型，父亲为O型），尽管没有双胎妊娠的证据。这种嵌合体的病因尚未得到解释。
