1. A simple technique is described for studying the oxidase action of bacteria by means of the oxidation of p-aminoleucomalachite green. 2. It is shown that pneumococci under aerobic conditions produced an oxidase when grown on suitable medium. The s

Summary and Conclusions In view of the observations that, following a dose of pneumococcus polysaccharide sufficient to produce “immunological paralysis” and a hypersusceptible state, mice retained in their tissues polysaccharide substances which

Summary and Conclusions The inferences which may be drawn from this study are: White mice may be immunized with a fraction of pneumococcus which is soluble in copper acetate in the presence of saturated sodium chloride and may be extracted with alcoh

Summary Pneumococci, both type I and type II, dried by application of acetone followed by vacuum desiccation, retain their antigenicity. The cell may be divided into acid soluble and acid insoluble constituents. The acid soluble fraction possesses mo

Summary and Conclusions Studies of the solubility of the pneumococcus antibody in alcohol reveal the following: Practically all the protective substance present in the original serum is insoluble in 15 to 20 per cent alcohol at 0°C. The precipitated

Bacteria vary in their ability to oxidize p-amino-leuco-malachite green.1 The conditions under which this chemical reaction is brought about by certain species of micro-organisms are quite definite and consist mainly of a proper substrate and a suita

In the course of our study on the antibody of antipneumococcus serum, it was repeatedly observed in protection tests that mice that had received injections with large doses of serum or with concentrated antibody solutions died while those receiving i
