Following its spread in the USA, West Nile Virus (WNV) has reemerged in the Mediterranean basin with a renewed pathogenicity. The introduction of WNV lineage 2 in Europe and its co-circulation with lineage 1 has resulted in a continuously changing epidemiological scenario, highlighting the importance of differential detection of the two lineages. The paper describes a new real-time PCR method for the detection and genotyping of the two main lineages of WNV. The method requires a single pair of primers and probes and is based on the analysis of highly conserved consensus sequences detected in the 5' terminus of the viral genome.
西尼罗河病毒(WNV)在美国传播之后,又在地中海盆地重新出现,且致病性有所增强。WNV 2型在欧洲的传入及其与1型的共同传播导致了流行病学情况不断变化,凸显了对这两个病毒株进行鉴别检测的重要性。本文描述了一种用于检测WNV两个主要病毒株并进行基因分型的新型实时PCR方法。该方法只需一对引物和探针,基于对在病毒基因组5'端检测到的高度保守共有序列的分析。
