Routine typing of Clostridium welchii

Proteolytic Enzymes of Clostridium welchii

1. Two optically isomeric open-chain pentapeptide esters have been synthesized. These peptides have the same sequence of amino-acid residues as gramicidin S. 2. A crystalline acylpentapeptide amide has been synthesized. Thiscompound is structurally analogous to the natural antibiotic in that its constituent amino-acids are arranged in the same sequence and are of the same optical configuration ...

Significance of the isolation of Clostridium welchii from routine blood cultures.

Clostridium welchii has been demonstrated in approximately 20% of contact plates taken from the antecubital fossa of 185 inpatients and outpatients and healthy staff. The highest incidence was in a group of 40 very ill patients. The isolation of the organism from blood cultures is not always of clinical significance. Skin preparation as at present practised is often inadequate to remove the spo...

Physiologic Action of Clostridium Welchii (type

Recent work reported from this laboratory (1 to 7) has shown that clostridia grow and produce toxins readily in anoxic muscle in zivo, and that they are readily introduced into dog muscles during the course of traumatizing procedures. Moreover, our previous experiments have suggested that these and perhaps other bacteria may be responsible for a toxic factor contributing to shock in traumatizin...

Clostridium welchii septicaemia complicating partial gastrectomy.

Case Report J.W., aged 38, a male office worker, was admitted on November 28, 1954, with a i6-year history of indigestion. A diagnosis of chronic duodenal ulcer with gross pyloric obstruction was confirmed radiologically. On January 6, 1955, partial gastrectomy was performed. There was a grossly scarred ulcer in the first part of the duodenum, causing marked stenosis; considerable induration of...
