multiplex detection of bacteria in complex clinical and environmental samples using oligonucleotide-coupled fluorescent microspheres

细菌性阴道病（BV）是一个经常性的多种微生物综合征的特点是在“正常” 菌群改变乳酸菌占主导地位， 其中包括阴道加德纳菌，Atopobium阴道的细菌种类占主导地位的菌群， 及其他1-3。这种情况是关联与对健康的负面结果，包括艾滋病毒收购4范围内，它可能难以管理临床 5 。此外，BV的诊断依赖于使用的各6,7数值标准取得的阴道拭子涂片革兰氏污渍。虽然这个诊断是简单，价格低廉，适合资源有限的环境，它可以受到相关的主观解释，并没有给出一个详细的个人资料的阴道菌群8的组成问题。最近的深度测序工作已经透露了​​一个丰富，形式多样的阴道菌群明确诊断相比，那些被认为正常9,10个人，这导致在11,12 BV的分子诊断的潜在目标识别与BV的个人采取的样本之间的差异。这些研究提供了丰富的有用信息，但深度测序尚未实际在临床上的诊断方法。最近，我们描述的方法，迅速 ​​分析多重格式的阴道菌群，使用寡核苷酸耦合的荧光珠检测在 Luminex公司平台13。像目前的革兰氏染色的方法，这种方法是快速和简单，但增加了额外的优势，利用分子测序探针设计研究产生的知识。因此，这种方法提供了一种方法来配置文件的阴道拭子，可用于诊断BV具有较高的特异性和灵敏度比赛中的主要微生物ared革兰氏染色同时提供更多的信息物种的存在和丰富的半定量和快速的方式。这种复用的方法是，远远超出了目前定量PCR分析，特别是生物，目前仅限于5或6个不同的检测单个样品14范围扩展。更重要的是，该方法不仅限于细菌在阴道拭子检测，可以很容易地适应快速分析几乎所有的微生物群落的兴趣。例如，我们最近开始申请污水处理厂使用这种方法的诊断工具的发展。
