消化道菌群对维持消化道机能有重要的调节作用。消化道菌群研究方法可分为两种，即微生物方法（分离培养）和分子生物学方法（基因分析），这两种方法各有利弊，分离培养仍然是基本和广泛使用的方法，但只能够检测生长在培养基上的细菌。对于整个消化道的微生物准确的定量和定性分析还有赖于基因分析方法。因此，这两种方法结合将成为了解消化道细菌的生态系统的关键。论文综述了消化道菌群的种类、分布、作用和研究方法，为消化道菌群研究提供参考。

Microflora in the digestive tract is an important regulatory role in maintaining the function of di-gestive system.These methods of detection are generally divided into two method-microbiological method (traditional culture method)and molecular biology technique(genetic analysis).Both techniques have ad-vantages and disadvantages.The microbiological technique is only able to detect identifiable bacteria that can be grown on available substrates.Nevertheless,the culture is still a fundamental and widely used method for detection of digestive tract microorganisms.However,for an accurate quantitative and qualita-tive investigation of the microbiology of the entire gastrointestinal tract,genetic method is required.The combination of both methods may become a critical element for understanding the ecosystem of digestive tract bacteria.This paper reviewed the functions,kinds,distribution and methods of detection in digestive tract microorganism to establish the basis for gastrointestinal tract microflora.
