Recently, sequences from a putative member of the Flaviviridae, GB virus C (GBV-C), were isolated from the serum of patients with cryptogenic hepatitis. These sequences were 83-99% identical at the nucleotide level. Because of the divergence between these GBV-C isolates, it is likely that the PCR-based detection assay yields false negatives, underestimating dramatically the true prevalence of GBV-C in human hepatitis. We report the design of a GBV-C consensus oligonucleotide primer pair that is superior to those originally described. These primers identify GBV-C sequences in cases of cryptogenic hepatitis, allowing a better estimation of the prevalence of this virus in human populations.
最近，从隐源性肝炎患者血清中分离出黄病毒科假定成员GB病毒C（GBV-C）的序列。这些序列在核苷酸水平上有83%-99%的同一性。由于这些GBV-C分离株之间存在差异，基于PCR的检测方法很可能产生假阴性结果，从而极大地低估了GBV-C在人类肝炎中的真实流行率。我们报告了一种GBV-C一致性寡核苷酸引物对的设计，该引物对比最初描述的引物对更优。这些引物可识别隐源性肝炎病例中的GBV-C序列，从而能更好地估计该病毒在人群中的流行率。
