Abstract

Shigella dysenteriae 7 (D7) strain was extracted by using the Westphal water/phenol method and the extract obtained (Aq/Ph 68‡C) was found to have the receptor activity against both T2 and T4 phages.

It was shown by the receptor neutralization test that the examined substance had receptor sites distinctive for T2 and T4 phages. The receptor sites for phage T2 had common antigen specificity with receptor sites of this phage localized inE. coli B in the lipoprotein fraction; the receptor sites of phage T4 had common antigen specificity with receptor sites to phage T4, localized inE. coli B in Aq/Ph 68‡ C extract. It is suggested that in spite of the different localization, the receptors for the same phage in the different bacterial species examined have common serological specificity.
