DNA derived from Mycobacterium leprae (grown in armadillos) was isolated, purified, and analyzed spectrophotometrically. The genome size and guanine-plus-cytosine content of M. leprae were 1.3 X 10(9) and 55.8%, respectively. Among selected strains of mycobacterial, nocardial and corynebacterial species, Corynebacterium sp. 2628 LB, isolated from a human leprosy patient, showed the highest DNA homology with M. leprae. Of the DNAs derived from mycobacteria, those of M. tuberculosis and M. scrofulaceum showed a comparatively high reassociation with the DNA of M. leprae.
从犰狳体内培养的麻风分枝杆菌中提取的DNA，经过分离、纯化后，用分光光度法进行了分析。麻风分枝杆菌的基因组大小和鸟嘌呤加胞嘧啶含量分别为1.3×10⁹和55.8%。在选定的分枝杆菌、诺卡氏菌和棒状杆菌菌株中，从一名人类麻风病患者身上分离出的棒状杆菌2628 LB菌株与麻风分枝杆菌的DNA同源性最高。在分枝杆菌的DNA中，结核分枝杆菌和瘰疬分枝杆菌的DNA与麻风分枝杆菌的DNA显示出相对较高的重缔合。
