通过比较7只冬眠6 × 6天和2 × 42天的十三排地松鼠（Citellus tridecemlineatus）的盲肠区系，探讨了冬眠对十三排地松鼠盲肠区系的影响。直接显微镜检查显示存在多种微生物，包括所有动物的原生动物。使用严格的厌氧技术，有可能分离出活跃松鼠总菌群的60 - 60%，但只有。30%是冬眠动物。几种不同类型的厌氧革兰氏阴性，非孢子杆状体在活动和冬眠动物中都占主导地位。在活动松鼠中存在革兰氏阳性，非孢子杆状体和球芽杆菌，但在42天冬眠松鼠中未分离到。非典型乳酸杆菌含量为106-108 /g，是活动松鼠需氧菌群的主要组成部分，但在冬眠期间至少减少了100倍。
The effect of hibernation on the caecal flora of the thirteen‐lined ground squirrel (Citellus tridecemlineatus) was determined by comparing the flora of 7 active squirrels with that of 6 × 6 days hibernators and 2 × 42 days hibernators. Direct microscopical examination showed the presence of a wide variety of micro‐organisms, including protozoa in all the animals. Using strict anaerobic techniques it was possible to isolate > 60% of the total flora of the active squirrels but onlyc.30% in the hibernators. Several distinct types of anaerobic Gram negative, nonsporing rods predominated in both the active and hibernating animals. Gram positive, nonsporing rods and coccobacilli were present in the active squirrels but were not isolated from the 42 days hibernators. Atypical lactobacilli present at 106–108/g formed the major part of the aerobic flora of the active squirrels but were reduced at least 100‐fold during hibernation.
