Randomly amplified polymorphic DNA (RAPD)-PCR patterns obtained with PER1 primer for 17 bifidobacterial strains. Analysis of the discriminatory power of the procedure applied was performed at a species level (a) - 1, DNA molecular marker; 2, B. adolescentis DSM 20087; 3, B. animalis NRRL B-41406; 4, B. bifidum DSM 204564; 5, B. breve DSM 20091; 6, B. catenulatum DSM 20224; 7, B. longum NRRL B-41409; 8, B. pseudocatenulatum DSM 20439; 9, B. pseudolongum DSM 20099; at a subspecies level (b) - 1, DNA molecular marker; 2, B. animalis subsp. animalis NRRL B-41406; 3, B. animalis subsp. lactis NRRL B-41405; 4, B. longum subsp. infantis ATCC 15697; 5, B. longum subsp. longum NRRL B-41409; 5, B. longum subsp. suis NRRL B-41407; 6, B. pseudolongum subsp. pseudolongum DSM 20099; 7, B. pseudolongum subsp. globosum DSM 20092; and at a strain level (c) - 1, DNA molecular marker; 2, B. adolescentis DSM 20087; 3, B. adolescentis DSM 20083; 4, B. adolescentis 20086; 5, B. breve DSM 20091; 6, B. breve NRRL B-41408; 7, B. pseudolongum DSM 20099; 8, B. pseudolongum 20094; 9, B. pseudolongum DSM 20095
