Abstract
DNA-DNA hybridization is a reliable method for determining the phylogenetic relationship between bacterial strains The hybridization kinetics for DNA from different slowly-growing mycobacteria were measured optically in a spectrophotometer. The results indicate that M. tuberculosis and M. bovis belong to one species. M. avium and M. intracellulare are two species, but some serotypes, now designated M. intracellulare, actually belong to M. avium.
摘要
DNA-DNA杂交是确定细菌菌株之间系统发育关系的可靠方法。用分光光度计以光学方式测量了来自不同生长缓慢的分枝杆菌的DNA的杂交动力学。结果表明，结核分枝杆菌和牛分枝杆菌属于同一物种。鸟分枝杆菌和胞内分枝杆菌是两个物种，但一些现在被指定为胞内分枝杆菌的血清型实际上属于鸟分枝杆菌。
