Abstract

Simultaneous oral administration of broth cultures of three strains of Escherichia coli isolated from sewage and an abattoir strongly inhibited the colonization of a subsequently administered strain of Salmonella typhimurium. The three strains were protective against the S. typhimurium strain under a variety of conditions: in different breeds and in chickens fed different diets. The strains were not equally effective against other salmonella strains. Oral administration of the strains produced a statistically significant reduction in the excretion of the S. typhimurium strain over a period of 7 weeks.

摘要

同时口服从污水和屠宰场分离出的三株大肠杆菌的肉汤培养物,能强烈抑制随后接种的鼠伤寒沙门氏菌菌株的定植。在多种条件下,这三株大肠杆菌对鼠伤寒沙门氏菌菌株具有保护作用:在不同品种以及食用不同日粮的鸡中均如此。这些菌株对其他沙门氏菌菌株的效果并不相同。口服这些菌株后,在7周的时间里,鼠伤寒沙门氏菌菌株的排泄量出现了具有统计学意义的下降。
