What is Which of the following range shows the generation time for leprosy bacillus? and explain in detail?
M. leprae cell division is by transverse fission. In mice, and presumably in man, it divides every 12-13 days (growth rate, mean generation or doubling time). This is a uniquely slow rate of multiplication even for slow-growing mycobacteria (M. tuberculosis, which also belongs to the slow-growing group, divides in about 20 hours), and is consistent with the long incubation period of the disease and its chronicity.
