To determine the effect of a certain diet on the intestinal flora of rats, the cecal flora of rats fed a low protein or low lysine diet was examined. Total counts of bacteria in the cecal contents of rats given the four kinds of diet (a normal protein diet, a low protein diet, a normal lysine diet and a low lysine diet) were not significantly different. The counts of Streptococcus, Enterobacteriaceae, and Clostridium perfringens in the cecal contents from rats fed the low protein diet were significantly lower than those from rats fed the normal protein diet. The count of Lactobacillus in the cecal contents of the low protein group were significantly lower than those of the control. But no significant difference was found between the levels of most of the free amino acids in the cecal contents of the low lysine group and those of the control group.
为确定某种饮食对大鼠肠道菌群的影响，对喂食低蛋白或低赖氨酸饮食的大鼠盲肠菌群进行了检查。给予四种饮食（正常蛋白饮食、低蛋白饮食、正常赖氨酸饮食和低赖氨酸饮食）的大鼠盲肠内容物中的细菌总数没有显著差异。喂食低蛋白饮食的大鼠盲肠内容物中链球菌、肠杆菌科和产气荚膜梭菌的数量显著低于喂食正常蛋白饮食的大鼠。低蛋白组盲肠内容物中乳酸杆菌的数量显著低于对照组。但低赖氨酸组盲肠内容物中大多数游离氨基酸的水平与对照组之间未发现显著差异。
