抄録

A biological significance was suggested to be shown by an acid-fastness map devised from investigation of the effect of ultraviolet irradiation on the acid-fastness of mycobacteria. Then, attempts were made to cultivate Mycobacterium lepraemurium Hawaii from nodules of infected mice in a cell-free, semi-synthetic soft agar medium. The basic composition of this medium was modified to some extent from that used for the successul cultivatioh of M. paratuberculosis Johnei.<br>Experiments were carried out repeatedly five times. Those organisms which had multiplied even to a limited extent were observed to form microcolony-like masses, which were composed of elongated, strongly acid-fast rods. It was interesting to note that when a medium contained both glycerol and glucose as carbon sources in addition to ferricion, it seemed to support the growth of M. lepraemurium to some extent.
