[Some properties of bacteriophages isolated in brynza manufacture].

According to the spectrum of lytic action towards 253 strains of Streptococcus lactis, 75 bacteriophages were subdivided into eight groups. According to their antigenic properties and morphology of their particles, the phages can be divided into three groups. Only two types of negative colony were found in the phages.
