The polymerase chain reaction (PCR) was used to detect Toxoplasma gondii DNA in cerebrospinal fluid (CSF) from 14 patients with AIDS by amplification of the repetitive B1 gene. Positive PCRs were obtained in CSF from four of nine patients with toxoplasmic encephalitis. CSF samples from five control patients were negative for T. gondii DNA by PCR.
采用聚合酶链反应(PCR),通过扩增重复的B1基因来检测14例艾滋病患者脑脊液(CSF)中的弓形虫DNA。9例弓形虫脑炎患者中有4例脑脊液PCR检测呈阳性。5例对照患者的脑脊液样本经PCR检测,弓形虫DNA呈阴性。
