CHEMICAL INVESTIGATIONS ON THE ACTIVE PRINCIPLES OF THE PHENOMENON OF LOCAL SKIN REACTIVITY TO BACTERIAL FILTRATES : II. PHYSICOCHEMICAL PROPERTIES

Autor: G, Shwartzman, S A, Morell

Publikováno v: The Journal of Experimental Medicine

Several physicochemical properties of the active principles of the phenomenon of local skin reactivity to bacterial filtrates have been investigated. Ultrafiltration through Zsigmondy filters of graded porosities has shown that the active substances

STUDIES ON STREPTOCOCCUS BACTERIOPHAGE : II. THE INFLUENCE OF LYTIC PRINCIPLES UPON THE AGGLUTINATION OF HEMOLYTIC STREPTOCOCCI

Autor: G, Shwartzman

Publikováno v: The Journal of Experimental Medicine

A series of experiments was carried out on various strains of streptococci in order to ascertain the changes which bacteriophage produces in the phenomena of agglutination of these organisms. The results can be placed in the following categories. 1.

STUDIES ON REGENERATION OF BACTERIOPHAGE : I. THE INFLUENCE OF PARTIAL ANAEROBIOSIS UPON REGENERATION OF A HIGHLY DILUTED LYTIC PRINCIPLE

Autor: G, Shwartzman

Publikováno v: The Journal of Experimental Medicine

The regeneration of an extreme dilution of bacteriophage in a large volume of broth, as described by Gratia and De Kruif, is due to the influence of partial anaerobiosis upon the regeneration of the principle. The influence of partial anaerobiosis up

CHEMICAL INVESTIGATIONS ON THE ACTIVE PRINCIPLES OF THE PHENOMENON OF LOCAL SKIN REACTIVITY TO BACTERIAL FILTRATES : I. PURIFICATION BY DIALYSIS, AND ATTEMPTS AT FRACTIONAL PRECIPITATION

Autor: G, Shwartzman, S, Morell, H, Sobotka

Publikováno v: The Journal of Experimental Medicine

A quantitative biological assay of the products obtained from the dialysis of B. typhosus, meningococcus, and B. coli culture filtrates has been undertaken. It was found that the active principles of the phenomenon of local skin reactivity to bacteri

CHEMICAL INVESTIGATIONS ON THE ACTIVE PRINCIPLES OF THE PHENOMENON OF LOCAL SKIN REACTIVITY TO BACTERIAL FILTRATES : III. APPLICATION OF DIALYSIS TO THE PRODUCTION OF THE ACTIVE PRINCIPLES IN FLUID MEDIA

Autor: S A, Morell, G, Shwartzman

Publikováno v: The Journal of Experimental Medicine

B. coli, meningococcus, and B. typhosus have been cultivated in a diffused broth medium, prepared by immersing cellophane bags containing saline into nutrient broth. An abundant growth occurred inside the bags, while the outside broth remained steril

STUDIES ON STREPTOCOCCUS BACTERIOPHAGE : I. A POWERFUL LYTIC PRINCIPLE AGAINST HEMOLYTIC STREPTOCOCCI OF ERYSIPELAS ORIGIN

Autor: G, Shwartzman

Publikováno v: The Journal of Experimental Medicine

1. The "sludge" phage obtained by Clark and Clark answers all requirements for pronouncing it identical with the classical bacteriophage. 2. The "sludge" phage failed to produce lysis in any of the 102 human pathogenic streptococci tested. 3. Numerou
