摘　　要：本文研究了季节因素对肠道重要菌群双歧杆菌和大肠杆菌的影响。在春、夏、秋、冬四季分别定量检测Ｔ２０名健康青年粪便中的上述两种菌，结果表明：两种细菌数值均有明显的季节变动规律，双歧杆菌秋季显著高于春、夏冬三季；大肠杆菌夏季显著高于冬、春季，而与秋季的差异无显著意义。ｚＬ歧杆菌与大肠杆菌在一年四季中的比值也有明显的季节特征，即秋季明显高于其它三季。he number of Bifidobecteria and E. Coli in stools of 20 young heaLthy students were measured in different seasons.The resuLtsshowed that:(1) Thenumber of Bifidobacteria was higher in aufumn than that in other seasons;(2)The number of E. Coli was higher in sun1mer than that in spring and winter, but similar to that in autumn;(3) The prop-ortion rate of Bifidobacteria to E. Coli(B/E) was nigher in autumn than that in other seasons Which showed a significant characteristlc of season.
