In this-the second of a series of studies on the prevalence of non-tuberculosis mycobacteria in Africa-the susceptibility of 228 cultures of non-tuberculosis mycobacteria isolated at tuberculosis laboratories in Nairobi, Kenya, and Lagos, Nigeria, to 7 laboratory strains of mycobacteriophages was examined. Of the 51 cultures found to be phage-sensitive, just over half (29) were saprophytic. In the cultures from East Africa, phage-sensitive strains were observed only among the saprophytes, whereas in those from West Africa such strains occurred also among unpigmented mycobacteria (Runyon's Group III). All but one strain of non-tuberculosis mycobacteria isolated from domestic animals in East Africa were found to be resistant to all 7 phages used. Unfortunately, the patterns of phage sensitivity showed such variety that it was concluded that phage-typing alone was unsuitable for the classification of non-tuberculosis mycobacteria.
这是关于非洲非结核分枝杆菌流行情况系列研究中的第二篇。研究检测了在肯尼亚内罗毕和尼日利亚拉各斯的结核病实验室分离出的228株非结核分枝杆菌培养物对7株实验室分枝杆菌噬菌体菌株的敏感性。在51株被发现对噬菌体敏感的培养物中，略超过半数（29株）是腐生菌。在东非的培养物中，仅在腐生菌中观察到对噬菌体敏感的菌株，而在西非的培养物中，此类菌株也出现在非色素沉着分枝杆菌（鲁尼恩分类法中的第三组）中。从东非家畜中分离出的非结核分枝杆菌，除一株外，其余所有菌株对所使用的7种噬菌体均有抗性。遗憾的是，噬菌体敏感性模式呈现出如此多样的情况，以至于得出结论：仅靠噬菌体分型不适用于非结核分枝杆菌的分类。
