Approximately 8--10 days after gum guar was added to the diet of rats, the total bacterial counts in their feces, in particular Clostridium and Lactobacillus, were increased, whereas the number of coliforms was reduced. In contrast to the long, slender, rod-shaped cells in the Gram-stained fecal smears of the control animals, the feces of the gum guar-fed animals showed a predominance of short, broad, Gram-positive rods. When gum guar was omitted from the diet of these animals, their feces could not be distinguished from those of control animals.
在给大鼠的饮食中添加瓜尔胶大约8 - 10天后，它们粪便中的总细菌计数增加，尤其是梭菌属和乳杆菌属，而大肠菌群数量减少。与对照动物革兰氏染色粪便涂片上细长的杆状细胞不同，喂食瓜尔胶的动物粪便中短而宽的革兰氏阳性杆菌占主导。当从这些动物的饮食中去除瓜尔胶时，它们的粪便与对照动物的粪便无法区分。
