title: [Comparison of genomes in Streptococcus thermophilus strains of different origins].
abstract: According to DNA hybridization data, thermophilic streptococci used in Russia as starters in the dairy industry are divided into 6 different genomovars, with a degree of DNA homology not exceeding 20-50%. The analysis of genomes from these genomovars using SmaI restriction endonuclease and pulsed-field gel electrophoresis revealed a wide variability of the genome size. In some strains, the genome size considerably exceeded 2000 kbp. Most of the strains studied contained plasmids about 120 kbp in size.
