An Analysis of 510 Strains ofCorynebacterium Diphtheriae

Abstract

Since Anderson, Happold, McLeod and Thomson (1931) described their division of the varieties ofCorynebacterium diphtheriaeinto three groups—gravis, intermediate andmitis—and submitted correlations with clinical types of diphtheria, several workers have published results of investigations which, for the most part, are against such a hard and fast classification.
