Adherence of gut microflora from Salmonella -free adult birds to the ceca of newly hatched chicks, and their role in protection against Salmonella was examined. The protective microflora remained attached to the cecal wall after four successive washings. Cultures of washed ceca taken from chicks 30 min to 1 h after treatment with fecal culture gave partial protection. Full protection was obtained with cultures from ceca taken 6 to 8 h after treatment.
研究了无沙门氏菌成年鸡的肠道微生物群对新孵化雏鸡盲肠的黏附情况及其在预防沙门氏菌方面的作用。经过连续四次冲洗后，保护性微生物群仍附着在盲肠壁上。用粪便培养物处理雏鸡30分钟至1小时后采集的冲洗后盲肠培养物提供了部分保护作用。用处理后6至8小时采集的盲肠培养物可获得完全保护作用。
