The bacteriophage sensitivity of the Streptococcus bovis population resident in the rumens of two fistulated sheep was monitored for 112 days. During this time, three changes in the bacteriophage sensitivity of S. bovis occurred in the absence of detectable bacteriophages. Identical changes in bacteriophage sensitivity occurred simultaneously in both animals and, except for the relatively short periods of changeover in phage sensitivity, the S. bovis population in the rumens of the two sheep was homogeneous with respect to phage sensitivity.
对两只装有瘤胃瘘管的绵羊瘤胃内定居的牛链球菌群体的噬菌体敏感性进行了112天的监测。在此期间，在未检测到噬菌体的情况下，牛链球菌的噬菌体敏感性发生了三次变化。两只动物的噬菌体敏感性同时发生了相同的变化，并且除了噬菌体敏感性转换的相对较短时期外，两只绵羊瘤胃内的牛链球菌群体在噬菌体敏感性方面是同质的。
