Growth curves and generation times of four strains of Myc. lepraemurium were compared with the inoculation method of foot-pad of mouse CF #1 strain.
The results obtained indicate that the generation time of the Kurume No.42 and the Kumamoto strains had two steps of growth curve; in the case of the Kurume No. 42 strain, the generation time in the first log phase was 2.2 days and that of second one was 2.5 days. In the case of Kumamoto strain, the first was 3.0 and second was 4.5 days, respectively. On the other hand, the Hawaiian and Fukuoka No.1 strains grew smoothly with one log phase; these generation times were 6.6 and 13.6 days, respectively.
