Bacillus sublilis (17), Diplococcus pneumoniae (16) and Haemophilus influenzae (18). In 1962 Catlin & Schloer (3) described a defined medium which satisfied minimal requirements for use in quantitative studies of transformation in Neisseria meningilidis with a streptomycin-resistance marker. Nutritional markers, however, do not seem to be in use among those who study transformation in Neisseria meningilidis. Actually, no reports can be found describing the introduction of nutritional marl< ers in this species of bacteria. This laboratory has been engaged for some time in studies on the metabolism of meningococci. With a view to the importance of genetic methods as a tool in metabolic research, investigations were also stal'led concerning meromixis in meningococci. In these studies nutritional markers have been extensively employed. The present communication describes the media used in these studies, the introduction of some nutritional markers into Neisseria meningitidis, and the behaviour of auxotrophs in mixed cultures.
