    • The present invention is directed to a method for identification of a pathogenic organism from a predetermined group of pathogens, comprising (i) isolating a clinical sample containing at least partially purified nucleic acid, (ii) subjecting at least a first aliquot of said clinical specimen to at least one amplification and detection reaction in one reaction vessel comprising (iia) an amplification step using at least a first set of amplification primers capable of amplifying a preselected nucleic acid sequence region from several or all members of said predetermined group of pathogens, (iib) a detection step using at least 2, 3 or multiple hybridization reagents, said reagents together being capable of specifically detecting a pre-selected nucleic acid sequence region from all members of said group of pathogens, said detection step (iib) comprising steps monitoring hybridization of each of said hybridization reagents at a pre-selected temperature, said hybridization being indicative for at least the genus of said pathogen present in the sample, and monitoring temperature dependence of hybridization, said temperature dependence being indicative for at least the species of said pathogen, and (iii) determining whether said amplification and detection reaction is indicative for the presence of a specific member of said pre-selected group of pathogens.
    • 本发明涉及从预定病原体组中鉴定病原生物的方法,其包括(i)分离含有至少部分纯化的核酸的临床样品,(ii)对所述临床标本的至少第一等分试样 至少在一个反应​​容器中进行扩增和检测反应,其包括(i)扩增步骤,使用至少第一组扩增引物,所述第一组扩增引物能够扩增来自所述预定病原体组的数个或全部成员的预选核酸序列区( iib)使用至少2,3或多个杂交试剂的检测步骤,所述试剂一起能够特异性检测来自所述病原体组的所有成员的预先选择的核酸序列区,所述检测步骤(iib)包括监测步骤 每个所述杂交试剂在预选温度下进行杂交,所述杂交是指示性的 至少存在于样品中的所述病原体的属和监测杂交的温度依赖性,所述温度依赖性指示至少所述病原体的种类,和(iii)确定所述扩增和检测反应是否表明存在 的所述预先选择的病原体组的特定成员。
