title: [Studies on the relationship of temperent phages and bacteriocines of streptococcus faecium (author's transl)].
abstract: Two bacteriocins (enterocin E1A and E1B) as well as a complete bacteriophage (PE1) were produced by Streptococcus faecium strain E1. Although the phage could be demonstrated by electron microscopy it was not possible to observe phages or phage-like particles in the purified preparation of the large enterocin E1B. Phage PE1 had a much smaller activity spectrum than that of enterocin E1A and E1B, inhibiting only one strain of Streptococcus faecium and one strain of Streptococcus salivarius. The enterocins were not neutralized by antiphage sera, thereby suggesting that the enterocins and the phage are chemically unrelated.
