Resistance of young chicks and poults to salmonella exposure was substantially increased by early oral administration of intestinal contents or feces from selected adult chickens. Protection was secured also by administering anaerobic broth cultures of intestinal microflora from selected donor birds. Protection, was substantial for 63 days, the longest period tested, although it could be overcome by severe exposure. The protective mechanism appears to be a consequence of competitive exclusion of salmonella by "normal" microflora of the gastrointestinal tract.
通过早期口服选定成年鸡的肠道内容物或粪便，幼雏和小火鸡对沙门氏菌感染的抵抗力显著增强。给予选定供体鸡肠道微生物群的厌氧肉汤培养物也能提供保护。在长达63天的最长测试期内，保护作用显著，尽管严重感染可克服这种保护作用。保护机制似乎是胃肠道“正常”微生物群对沙门氏菌进行竞争性排斥的结果。
