    • The present invention relates, e.g. , to a composition comprising OspC polypeptides from Lyme Disease-causing Borrelia species, wherein the composition comprises one or more isolated polypeptides from OspC families as follows: (a) at least one of each of K, B, and J; or (b) at least one of each of K and E; or (c) at least one of each of K and F. These polypeptides bind specifically to antibodies induced by a causative agent of Lyme disease (a pathogenic Borrelia ), e.g. in a sample from a subject having Lyme disease, and exhibit a high degree of cross-reactivity with OscC polypeptides from other families. Therefore, the noted combinations of polypeptides can be used to diagnose infection from broad cross-section of Borrelia . Also disclosed are diagnostic reagents and kits comprising compositions of the invention, methods for diagnosing infection by Borrelia , and vaccines against Borrelia infection.
    • 本发明涉及例如包含来自莱姆病引起的疏螺旋体物种的OspC多肽的组合物,其中所述组合物包含来自OspC家族的一种或多种分离的多肽,如下:(a)K,B和 焦耳; 或(b)K和E中的至少一个; 或(c)K和F中的至少一个。这些多肽特异性结合由莱姆病(致病性疏螺旋体)病原体引起的抗体。 在来自具有莱姆病的受试者的样品中,并且与来自其他家族的OscC多肽表现出高度的交叉反应性。 因此,所指出的多肽的组合可以用于诊断来自疏螺旋体的宽横截面的感染。 还公开了包含本发明组合物的诊断试剂和试剂盒,用于诊断Borrelia感染的方法和针对Borrelia感染的疫苗。

    • Nucleic acid probes and molecular method to identify the varieties and genotypic groups within C. neoformans species complex. The method employs a flow cytometer with a dual laser system that allows the simultaneous detection of different target sequences in a multiplex and high-throughput format. The assay uses a liquid suspension hybridization format with specific oligonucleotide probes that are covalently bound to the surface of fluorescent color-coded microspheres. Biotinylated target amplicons, which hybridized to their complementary probe sequences, are quantified by the addition of the conjugate, streptavidin-R-phycoerythrin. The assay is specific and sensitive, and allows discrimination of 1bp mismatch with no apparent cross-reactivity and is capable of detecting 101 to 103 genome copies. The assay can be used directly with yeast cells or isolated DNA, can be undertaken in less than one hour following PCR amplification and permits identification of species in a multiplex format. In addition, to multiplex capability, the assay allows simultaneous detection of target sequences in a single reaction.
    • 核酸探针和分子方法鉴定新型隐球菌物种复合物中的品种和基因型组。 该方法采用具有双激光系统的流式细胞仪,其允许以多路和高通量格式同时检测不同的靶序列。 该测定法使用液体悬浮杂交形式与特定的寡核苷酸探针共价结合荧光色编码微球体的表面。 通过加入缀合物链亲和素-R-藻红蛋白来定量与其互补探针序列杂交的生物素化靶扩增子。 该测定是特异性和灵敏的,并且允许区分1bp错配,没有明显的交叉反应性,并且能够检测101至103个基因组拷贝。 该测定可以直接用于酵母细胞或分离的DNA,可以在PCR扩增后不到一小时内进行,并允许以多重格式鉴定物种。 此外,为了复用能力,该测定允许在单次反应中同时检测靶序列。
