Abstract
Summary
It was shown that differences in oxidative metabolism of L-glutamic acid observed with V and W variants of S. typhi are related to enzymatic activities of each strain as reported by Baron. Results obtained with one strain varied greatly and the differences were only detectable when experiments were carried out with pure V and W forms of each strain. Variants V and W of S. typhi when cultured at 18–20°C showed higher oxidative activity toward L-glutamic acid than with V and W forms even when no Vi antigen could be detected.
