Abstract
Electron microscope studies have been made of a number of phages of lactic streptococci, seven of which were phages of Streptococcus lactis C10. Two of the phages are thought to be identical; five have been classified by the method of Tikhonenko as belonging to group IV (phages with noncontractile tails) with type III tail plates; one belongs to group V (phages with tails possessing a contractile sheath). Both prolate polyhedral heads and isometric polyhedral heads are represented among the group IV phages. The phage drc3 of S. diacetilactis DRC3 has been shown to have similar structure to the group IV phages of S. lactis C10 with prolate polyhedral heads. The phages ml1, hp, c11, and z8 of the S. cremoris strains ML1, HP, C11, and Z8, respectively, were shown to belong to the group IV phages with type III tail plates by the method of Tikhonenko. All had octahedral heads and tended to be larger than most of the other phages studied.
