肠道微生物群的组成与各种疾病状态有关,最明显的是炎症性肠病,肥胖和营养不良。这强调了肠道微生物群的分析可能是临床诊断的一个有趣目标。目前,最常用的样本类型是粪便和粘膜活检标本。由于采样方法、样品的储存和处理会影响微生物群分析,因此每种样品类型都有其自身的局限性。用于常规诊断的理想样品类型应该易于以标准化方式获得,而不会干扰微生物群。直肠拭子可能满足这些标准,但对这些样本类型的微生物群分析知之甚少。在这项研究中,我们研究了直肠拭子在临床常规环境中用于各种胃肠疾病患者肠道微生物群分析的特征和适用性。我们发现,直肠拭子似乎是一种方便的人类肠道微生物群采样手段。拭子可以按需进行,只要患者出现;拭子衍生的微生物群谱是可再现的,无论它们是由患者在家中还是由门诊环境中的医疗专业人员收集的,并且可能非常适合临床诊断和大规模研究。
The composition of the gut microbiota is associated with various disease states, most notably inflammatory bowel disease, obesity and malnutrition. This underlines that analysis of intestinal microbiota is potentially an interesting target for clinical diagnostics. Currently, the most commonly used sample types are feces and mucosal biopsy specimens. Because sampling method, storage and processing of samples impact microbiota analysis, each sample type has its own limitations. An ideal sample type for use in routine diagnostics should be easy to obtain in a standardized fashion without perturbation of the microbiota. Rectal swabs may satisfy these criteria, but little is known about microbiota analysis on these sample types. In this study we investigated the characteristics and applicability of rectal swabs for gut microbiota profiling in a clinical routine setting in patients presenting with various gastro-intestinal disorders. We found that rectal swabs appeared to be a convenient means of sampling the human gut microbiota. Swabs can be performed on demand, whenever a patient presents; swab-derived microbiota profiles are reproducible, whether they are gathered at home by patients or by medical professionals in an outpatient setting and may be ideally suited for clinical diagnostics and large-scale studies.
