The effect of oral inoculation with anaerobic cultures of cecal microflora from adult broiler chickens and dietary lactose on Salmonella typhimurium cecal colonization was evaluated in bobwhite quail chicks. One-day-old chicks were divided into four groups and provided 1) no anaerobic cultures, no lactose (control); 2) anaerobic cultures; 3) 2.5% lactose (wt/vol) in drinking water; or 4) anaerobic cultures and lactose. All groups were challenged orally with 10(4) S. typhimurium at 2 days of age. Salmonella growth in the cecal contents was significantly decreased (P < .05) at 15 days of age in each of the three treatment groups as compared with controls. Protection against Salmonella colonization was highest in the treatment group provided anaerobic cultures only. The results indicated that cecal flora from adult chickens enhances Salmonella colonization resistance in quail chicks.
在雏鹑中评估了用成年肉鸡盲肠微生物群的厌氧培养物经口接种以及日粮乳糖对鼠伤寒沙门氏菌在盲肠定殖的影响。1日龄雏鸡被分为四组，分别给予：1）不接种厌氧培养物，不添加乳糖（对照组）；2）厌氧培养物；3）饮用水中添加2.5%乳糖（重量/体积）；或4）厌氧培养物和乳糖。所有组在2日龄时经口接种10⁴ 鼠伤寒沙门氏菌。与对照组相比，在15日龄时，三个处理组中每个组盲肠内容物中的沙门氏菌生长均显著降低（P < .05）。仅给予厌氧培养物的处理组对沙门氏菌定殖的保护作用最高。结果表明，成年鸡的盲肠菌群增强了雏鹑对沙门氏菌定殖的抵抗力。
