[Action of desoxyfructo-serotonin on Mycobacterium leprae. Results of inoculation of human biopsy specimens in the mouse after a year of treatment].

M. leprae, extracted from cutaneous biopsies of 4 out of 7 patients treated with DFS during one year at doses of 1000 to 1500 mg/day were injected in mouse foot pads. Bacterial multiplication was observed in each case. The purely bacteriostatic activity of DFS for M. leprae, previously observed in mice, is thus confirmed. The eventual place of DFS in the therapy of leprosy is discussed.
