检查了不明原因的死胎，Ｂ超检查发现水肿和／或胸、腹水的胎儿，畸形儿及死亡的新生儿共１１例，采取母血、羊水和脐血标本，应用ＰＣＲ技术进行检测。结果：母血标本８例，４例Ｂ１９阳性，羊水和脐血标本１１例，４例阳性，胎儿感染率为３６３６％。１１例中有４例胎儿水肿，３例Ｂ１９阳性，Ｂ１９阴性的１例经检查证实为母儿Ｒｈ血型不合，抗人球蛋白实验阳性，系免疫性水肿。Ｂ１９检查的病例中有２例是双胎妊娠，其４个胎儿均受感染。此外，Ｂ１９阳性的病例中有２例胎儿伴短肢畸形，是巧合还是感染所致，尚不能作出定论
Check unexplained stillbirth, B-ultrasound found edema and / or chest, ascites fetuses, deformed children and neonatal deaths in 11 cases, using maternal blood, amniotic fluid and cord blood samples, the application of PCR detection. Results: There were 8 maternal blood samples, 4 positive samples of B19, amniotic fluid and umbilical cord blood samples, 4 were positive and the fetus infection rate was 3636%. 4 cases of fetal edema in 11 cases, 3 cases of B19-positive, B19-negative in 1 case confirmed by examination of the Rh-maternal incompatibility, anti-human globulin test was positive, Department of immune edema. Two of the B19 examined cases were twin pregnancies and all four fetuses were infected. In addition, 2 cases of B19 positive cases of fetal short-limb deformity, coincidence or infection caused, yet to be conclusive
