Title:
DIGITAL ANALYSIS OF MICROBIAL FLORA
Document Type and Number:
WIPO Patent Application WO/2020/218553
Kind Code:
A1
Abstract:
The present disclosure provides a method for evaluating an absolute number of a microbial flora composition inexpensively, simply, and/or highly accurately. The method for analyzing a microbial flora composition comprises a step for evaluating the microbial flora composition from a specimen including amplified nucleic acids derived from respective cells in the microbial flora. According to this method, in an execution before whole-genome sequencing, the absolute number of the microbial flora can be evaluated inexpensively and simply, and after whole-genome sequencing, it becomes possible to compare with a long gene sequence by narrowing, from digital sequence information, information to be analyzed, thereby increasing the degree of accuracy.
