    • Disclosed are methods and compositions for conducting assays of samples utilizing polymerase chain reactions (“PCRs”) in the detection of serotypes of Chlamydia trachomatis capable of causing lymphogranuloma venereum (“LGV”). These serotypes are in the L group of Chlamydia trachomatis, and include the L I, L II, and L III serotypes. These assays take advantage of a deletion occurring in the cytotoxin gene locus specific to the L I, L II, and L III serotypes. The genome of each of these three serotypes contains the nucleotide sequence of SEQ ID NO:1 and the nucleotide sequence of SEQ ID NO:2, wherein the nucleotide at the 3′ end of SEQ ID NO:1 and the nucleotide at the 5′ end of SEQ ID NO:2 are contiguous, and wherein the deletion point of the cytotoxin gene locus is located between these two nucleotides. Each of these assays employs a first primer having a nucleotide sequence flanking one side of the deletion point and a second primer having a nucleotide sequence flanking the other side of the deletion point, wherein the first primer and the second primer are capable of hybridizing respectively to the plus strand and the minus strand of the genome of Chlamydia trachomatis during the PCR. Synthesis during the PCR of a sequence-specific amplicon containing this deletion point indicates that the sample contains nucleic acid specific to an LGV-causing serotype of Chlamydia trachomatis. The amplicon can be detected during real-time PCR using a labeled oligonucleotide as a probe, or after end-point PCR by gel electrophoresis.
    • 公开了用于在检测能引起淋巴肉芽肿(“LGV”)的沙眼衣原体血清型中使用聚合酶链反应(“PCR”)进行测定的方法和组合物。 这些血清型是L组沙眼衣原体,包括L I,L II和L III血清型。 这些测定利用在L I,L II和L III血清型特异性的细胞毒素基因位点中发生的缺失。 这三种血清型中的每一种的基因组含有SEQ ID NO:1的核苷酸序列和SEQ ID NO:2的核苷酸序列,其中SEQ ID NO:1的3'末端的核苷酸和5' SEQ ID NO:2的末端是连续的,并且其中细胞毒素基因位点的缺失点位于这两个核苷酸之间。 这些测定中的每一个采用具有位于缺失点的一侧侧翼的核苷酸序列的第一引物和具有位于缺失点另一侧侧翼的核苷酸序列的第二引物,其中第一引物和第二引物能够分别与 PCR期间沙眼衣原体基因组的正链和负链。 在含有该缺失点的序列特异性扩增子的PCR期间的合成表明样品含有对造成衣原体沙眼衣原体的导致LGV的血清型特异的核酸。 使用标记的寡核苷酸作为探针,或通过凝胶电泳进行终点PCR后,可以在实时PCR中检测扩增子。

    • Methods and compositions useful in the detection and identification of species of Candida are disclosed. The compositions are combinations of oligonucleotides, where the forward primers of the primer pairs have identical sequences, while each reverse primer of the primer pairs has a unique sequence relative to all of the other reverse primers; or the reverse primers of the primer pairs have identical sequences, while each forward primer of the primer pairs has a unique sequence relative to all of the other forward primers. The oligonucleotides also include probes capable of detecting these amplicons, and sequencing primers for determining, in primer extension reactions, the nucleotide sequences contained within the amplicons. The detection of an amplicon indicates that the sample contains at least one isolate of Candida albicans, Candida glabrata, Candida parapsilosis, or Candida tropicalis, and the nucleotide sequence data is used to determine which of these four Candida species is present.
    • 公开了用于检测和鉴定假丝酵母菌种的方法和组合物。 组合物是寡核苷酸的组合,其中引物对的正向引物具有相同的序列,而引物对的每个反向引物相对于所有其它反向引物具有唯一的序列; 或引物对的反向引物具有相同的序列,而引物对的每个正向引物相对于所有其它正向引物具有唯一的序列。 寡核苷酸还包括能够检测这些扩增子的探针和测序引物,用于在引物延伸反应中测定扩增子中包含的核苷酸序列。 扩增子的检测表明该样品含有至少一种白色念珠菌,光滑假丝酵母(Candida glabrata),假丝酵母​​(Candida parapsilosis)或热带假丝酵母(Candida tropicalis))的分离物,并且使用核苷酸序列数据来确定这四种假丝酵母属中存在哪一种。

    • Disclosed are oligonucleotides useful in methods for determining whether a sample contains Atopobium vaginae or has an increased likelihood of containing Atopobium vaginae, an organism which is seen in conjunction with bacterial vaginosis or is a causative agent of bacterial vaginosis. These oligonucleotides, which have nucleotide sequences derived from a segment of the genome of Atopobium vaginae, are useful as forward and reverse primers for a polymerase chain reaction using nucleic acids from a biological sample as a template, and as probes for detecting any resultant amplicon. Detection of an amplicon indicates the sample contains Atopobium vaginae or has an increased likelihood of containing Atopobium vaginae.
