概括

这项研究研究了正常眼睛的眼内微生物殖民,使用下一代测序. 结果表明,没有明显的眼内微生物组,与眼表面微生物组不同.

科学领域:

微生物学微生物学
眼科医生眼科眼科
基因组学就是基因组学.

背景情况:

目表面微生物群的特征是,但正常眼睛的眼内微生物殖民仍然在很大程度上是未知的.
了解眼睛内的微生物环境对于眼睛健康和疾病研究至关重要.

研究的目的:

在正常人眼中调查潜在的眼内微生物群的存在和特征.
要区分眼睛表面微生物群和任何潜在的眼内微生物群.

主要方法:

16S rDNA基因的下一代测序 (NGS) 在白内障手术患者的水性幽默样本上进行.
对照样本包括来自患者和健康捐赠者的空气拭子和结膜拭子.
用于细菌鉴定,采用了DNA提取,基因放大 (V3-V4区域),测序,消毒和数据库匹配.

主要成果:

低DNA含量 (0-1.49 ng/μL) 足以在所有样本中进行分析.
确定的主要细菌系是Acinetobacteria (48%),Proteobacteria (26%),Firmicutes (14%),Acidobacteria (8%) 和Bacteroidetes (2%).这些细菌是主要的细菌.
水性幽默和结膜样本显示出类似的细菌概况,包括水borne物种,而空气抹布呈现出不同的频谱.

结论:

这项研究证实了眼睛表面微生物组的存在.
在正常的眼睛中没有识别出明显的眼内微生物群,这表明它不在眼睛的内部环境中.
这些发现暗示,在水性幽默中观察到的微生物特征可能起源于眼睛表面或外部污染.

关键词:

前腔室的流体是前腔室的流体.眼睛眼睛眼睛眼睛眼睛微生物组是一个微生物组.这是下一代测序.

Next-generation Sequencing

Next-generation Sequencing

The first human genome sequencing project cost $2.7 billion and was declared complete in 2003, after 15 years of international cooperation and collaboration between several research teams and funding agencies. Today, with the advent of next-generation sequencing technologies, the cost and time of sequencing a human genome have dropped over 100 fold.

RNA-seq

RNA-seq

RNA sequencing, or RNA-Seq, is a high-throughput sequencing technology used to study the transcriptome of a cell. Transcriptomics helps to interpret the functional elements of a genome and identify the molecular constituents of an organism. Additionally, it also helps in understanding the development of an organism and the occurrence of diseases.
Before the discovery of RNA-seq, microarray-based methods and Sanger sequencing were used for transcriptome analysis. However, while...
