| 摘 要： | 目的快速全面检测感染细胞、疫苗等多种生物制品中的支原体.方法从多种支原体的16SrRNA核酸序列中选择了两段高度保守的核酸序列,作为支原体种属特异性引物,对标本进行检测.结果用这对种属特异性引物对已知阳性的50份标本进行检测,检测结果显示全部为阳性.应用于实践,检测了89份疫苗标本,阳性率为31.4%,而用常规培养法检测阳性率为12.3%.结论用该种属特异性引物检测支原体具有检测速度快、检测灵敏度高、特异性强等优点.

| Abstract: | Objective To detect mycoplasma species mainly infected in cell cultures and vaccinum.Methods PCR primers were designed according to the published sequences of 16 s rRNA of Mycoplasma in genbank.Mycoplasma species were detected by species-specific PCR.Results To detect 50 samples by using species-specific PCR,the results are all positive.In practice,we detected 89 vaccinum samples by using species-specific PCR method and culture method,31.4% and 12.3% respectively showed the positive.Conclusion The species-specific PCR for mycoplasma could identify mycoplasma with high speed,sensitivity and specification in cell culture. |
