Evidence for frequent lysogeny in lactobacilli: temperate bacteriophages within the subgenus Streptobacterium.
A total of 17 of 21 Lactobacillus strains of the subgenus Streptobacterium were lysogenic. Two different temperate phages isolated from such lysogens are very similar to Lactobacillus casei phage PL-1. The narrow host range of bacteriophage PL-1 appears to be caused by homoimmunity.
