ISOLATION OF CLOSTRIDIUM TETANI FROM SOIL.

Sanada, Ichiro (Kanazawa University, Kanazawa, Japan), and Shoki Nishida. Isolation of Clostridium tetani from soil. J. Bacteriol. 89:626-629. 1965.-The higher the temperatures applied to soil specimens, the weaker the toxigenicity of Clostridium tetani strains isolated from them. The glucose- and maltose-fermenting ability of these isolates was inversely proportional to their toxigenicity. The biological properties of atoxic strains were indistinguishable from those of C. tetanomorphum. Since a considerable number of toxic strains fermented glucose and maltose, these criteria are of doubtful value for differentiating C. tetani from C. tetanomorphum.
