title: [Comparative study of moderate and virulent phages of mesophilous lactic acid streptococci].
abstract: A method has been developed to identify phage containing mesophilous lactic acid streptococci. The method is based on the chloroform treatment of young cultures. The isolated moderate phages P4St and P6St are morphologically identical and serologically related to one another and to virulent phages P1Sv, P2Sv, P3Sv, P12Sv, P13Sv that can be isolated in industrial phagolysis.
