    • Methods are described herein for detecting and identifying distinct species of nucleic acids, in a single container, for example, from a certain genus of infectious agents or otherwise causative agents comprising, for example, providing a forward PCR primer common to a homologous gene region between the distinct species, and providing a reverse PCR primer common to a homologous gene region between the distinct species, to thereby define a PCR target region amongst the species, and providing a first oligonucleotide probe specific to a nucleic acid sequence within the target region that is characteristic of a first species, providing a second oligonucleotide probe specific to a nucleic acid sequence within the target region that is characteristic of a second species, wherein the first and second oligonucleotide probes are each detectably labeled with distinctly different detectable labels, conducting a PCR reaction in the container by means of the primers to amplify the target region amongst the species, and detecting the distinct labels, thereby identifying distinct species of nucleic acids corresponding to distinct species of infectious agents. Methods are preferred, for example, wherein the infectious agent is a member of the Herpesviridae family.
    • 在本文中描述了用于在单个容器中,例如来自某一感染因子或其他致病因子的单个容器中检测和鉴定不同种类的核酸的方法,所述诱导剂包括例如提供在同源基因区域之间共同的正向PCR引物 并且提供与不同物种之间的同源基因区域共有的反向PCR引物,从而在物种间限定PCR靶区域,并提供对靶区域内的核酸序列特异的第一寡核苷酸探针, 提供对目标区域内具有特征的第二种类的核酸序列特异性的第二寡核苷酸探针,其中第一和第二寡核苷酸探针各自可检测地用明显不同的可检测标记物标记,进行PCR反应 在容器中通过引物扩增目标区域amo 并检测不同的标签,从而识别与不同种类的感染因子相对应的不同种类的核酸。 方法是优选的,例如,其中感染剂是疱疹病毒科家族的成员。
