A discussion is conducted on the results of the application of the technique for hybridizing nucleic acids to the detection of cytomegalovirus (CMV) in urine samples. For this purpose, 2 probes from 2 different regions of the genome of the AD169 strain of CMV were used. The results were compared with those obtained by the technique for the detection of early fluorescent antigens (DEFA) in 2 groups of patients at risk of suffering from CMV infections. After assessing the usefulness of the two probes in detecting CMV in urine samples, it was shown that probe B from the region which codes the synthesis of early viral proteins had a coincidence and specificity levels regarding the reference test (DEFA) significantly superior to that of probe A. The results of hybridization may be ready within 48 and 72 hours. The qualification of the technique fo its application to virological diagnosis is discussed.
对核酸杂交技术在尿液样本中检测巨细胞病毒(CMV)的应用结果进行了讨论。为此,使用了来自CMV AD169株基因组2个不同区域的2种探针。将结果与通过检测早期荧光抗原(DEFA)技术在两组有CMV感染风险患者中获得的结果进行了比较。在评估这两种探针在检测尿液样本中CMV的有用性后,结果表明,来自编码早期病毒蛋白合成区域的探针B与参考测试(DEFA)相比,其一致性和特异性水平明显优于探针A。杂交结果可在48至72小时内得出。讨论了该技术应用于病毒学诊断的适用性鉴定。
