[Phage conversion of the antigens in Escherichiae and Shigellae. 2. Conversion of the somatic antigen in Shigella flexneri with the moderate E. coli 0129 phage].
The authors studied the converting activity of the moderate EF5 phage isolated from the lysogenic E. coli 0129 strain. It was shown that this phage converted the O-antigen with the detection of the type antigen V in the strains of Sh. flexneri of the serological type la and y-variant. The converted cultures contained the type antigen V and were identical by the antigenic properties to one another and the Sh. flexneri of the serological type 5 and E. coli 0129. A conclusion was drawn that phages converting the antigens of Sh. flexneri could be encountered in escherichia and could modify the antigens in Sh. flexneri and escherichia possessing the antigenic factor 3,4.
