[Effect of chemotherapy on certain species of the Cohn Bacillus]

This study covers investigations on 15 strains of 7 species included in the genus Bacillus Cohn; by using discs which had absorbed the chemotherapeutic agents. In all, effects of 12 chemotherapeutic substances were followed. The results show that in addition to the normal determination methods it is possible to separate some of the varieties of these species with the help of this technique.
