PREPARATION OF COLLODION SACS FOR USE IN BACTERIOLOGY

Preparation of Collodion Sacs for Use in Bacteriology

A standardized method is described in detail by which collodion sacs suitable for intraperitoneal incubation and for other bacteriological experiments may be produced in large numbers, sterilized, and handled with convenience and the minimum danger of contamination. Various factors influencing permeability have been subjected to experiment. Like Brown, we found that immersion in alcohol is the ...

Effect of Sulfanilamide Injected Subcutaneously into Rabbits upon Hemolytic Streptococci Contained in Collodion Sacs Implanted Intraperitoneally.

Experiments were undertaken to determine the effect of sulfanilamide upon hemolytic streptococci growing within the animal body, yet protected by collodion membranes from phagocytosis. The method of manufacturing the collodion sacs used in the experiments has previously been described (Harris, 1939). Theories regarding the r6le of phagocytosis in the drug's action have been amply discussed by L...
