Present state of lactic acid bacteria phage taxonomy.
Recent developments in molecular taxonomy of bacteriophages of lactobacilli and lactic streptococci are presented. DNA homology appears to be the most valid criterion in studying phage taxonomy. For each bacterial species, phages can be classified in a few families according to this criterion. A fair correspondence is observed between the groups differentiated by DNA-DNA hybridization and those differenciated by protein composition. In 2 bacterial species, a close relatedness between some virulent and temperate phages has been demonstrated. The presence of homologous sequences in the genome of various phages may play an important role in their evolution. For future taxonomic studies, some phages representative of DNA homology groups are proposed as reference phages.
