作者利用PCR技术动态地观察 5 0名孕妇早、中、晚各孕期外周静脉血、晨尿、羊水及其子女新生儿脐带血中RCMV、HSV、TOX的感染频率 ,发现 5 0名孕妇的总感染频率为 93% ;4种标本中三种病原体各自感染频率为HCMV :血 16 .3%、尿 16 .3%、羊水 3 .3 %、新生儿脐带血 4.35 % ;HSV :血 10 .9%、尿 13.0 4%、羊水 1.0 9%、新生儿脐带血 1.0 9% ;TOX :血13 .0 4%、尿 14.6 7%、羊水 3 .8%、新生儿脐带血 2 .17% ;不同阶段三种病原体感染频率情况分别为 :孕早期 :HCMV(18% ) >TOX(14% ) >HSV (4 % ) ;孕中期HCMV (5 2 % ) >TOX(4 8% ) >HSV (36 % ) ;孕晚期 :HCMV (5 0 % ) >TOX (4 8% ) >HSV(36 % ) ;羊水 :TOX(14% ) >HCMV(12 % ) >HSV(4 % ) ;新生儿脐带血 :HCMV(16 % ) >TOX(8% ) >HSV(4 % )。 3种病原体在各标本中的感染频率为 :孕早期 :HCMV(血 3.2 6 % ;尿 1.6 3% ) >TOX(血 2 .17% ;尿 1 6 3% ) >HSV(血 1.0 9;尿 0 ) ;孕中期 :HCMV(血 7.0 7% ;尿 7.0 7% ) >HSV(血 5 .43 % ;尿 7.6 1% ) >TOX(血 4 35 % ;尿 5 .43 % ) ;孕晚期 :TOX(血 6 .5 2 % ;尿 7.6 1% ) >HCMV(血 5 .98% ;尿 7.6 1% ) >HSV(血 4 35 %、尿 5 .43 % ) ;羊水 :TOX(38% ) >HCMV(3 .2 6 % ) >HSV(1.0 9% ) ;新生儿脐带血 :HCMV(4 35
The authors used PCR technology to dynamically observe the frequency of infection of RCMV, HSV and TOX in peripheral blood, morning urine, amniotic fluid and neonatal umbilical cord blood of 50 pregnant women in early, middle and late pregnancy, and found that 50 The frequency of infection was 93%. The infection frequency of each of the three pathogens in each of the four specimens was HCMV: 16.3% of blood, 16.3% of urine, 3.3% of amniotic fluid, 4.35% of cord blood of neonates; HSV: 10.9 of blood %, Urinary 13.0 4%, amniotic fluid 1.0 9%, neonatal umbilical cord blood 1.0 9%; TOX: blood 13.04%, urine 14.6 7%, amniotic fluid 3.8%, newborn cord blood 2.17%; different The frequency of infection of the three pathogens in the stage were as follows: first trimester of pregnancy: HCMV (18%)> TOX (14%)> HSV (4%); second trimester HCMV (52%) TOX ; Third trimester of pregnancy: HCMV (50%)> TOX (48%)> HSV (36%); amniotic fluid: TOX : HCMV (16%)> TOX (8%)> HSV (4%). The frequency of infection of the three pathogens in each sample was as follows: first trimester pregnancy: HCMV (blood 3.2 6%; urine 1.6 3%)> TOX (blood 2.17%; urine 136%)> HSV 0); second trimester: HCMV (blood 7.07%; urine 7.07%)> HSV (blood 5.43%; urine 7.61%)> TOX HSV (blood 35.3%; urinary 5.43%); amniotic fluid: TOX (38%); > HCMV (3.26%)> HSV (1.09%); neonatal cord blood: HCMV (4 35
