Pseudomonas fragi strain WY and its homologous bacteriophage were added in varying concentrations to sterile skim milk which was stored at 7 C for 72 hr. When the initial concentration of the bacterial host was 100,000/ml, addition of as few as 10 plaque-forming units per ml of bacteriophage resulted in significantly lower counts in treated skim milk than in the controls which contained no phage. There was no significant effect, however, when the phage input was 1 in 10 ml and the bacterial count was 1,000 or 100,00/ml. No differences in bacterial counts occurred even when the phage concentration was 1,000/ml if the initial bacterial concentration was only 1,000/ml.
将不同浓度的草莓假单胞菌菌株WY及其同源噬菌体添加到无菌脱脂乳中，并在7℃下储存72小时。当初始细菌宿主浓度为100,000/ml时，每毫升添加低至10个噬菌斑形成单位的噬菌体，处理后的脱脂乳中的细菌计数显著低于不含噬菌体的对照。然而，当噬菌体输入量为每10毫升1个且细菌计数为1,000或100,00/ml时，没有显著影响。如果初始细菌浓度仅为1,000/ml，即使噬菌体浓度为1,000/ml，细菌计数也没有差异。
