Isolation from Shigellae of receptor substances for bacteriophages. Receptor substances for the phages of the lysogenic strain B. Lisbonne were prepared from Shigellae strains. Ex traction in the cold with 5 p. 100 trichlor acetic acid was found convenient for isolating the receptors from the S strains. Those from the R strains could be extracted by treating the bacteria suspended in water with an equume of 90 p. 100 phenol at 68 C. The receptor substances contain sugars and fatty acids and might be lipo-polysaccharids. Purification and chemical analysis of these receptors are in progress.
