A total of 17 Bifidobacterium pseudocatenulatum strains isolated from infant faeces and 1 Bifidobacterium pseudocatenulatum type strain were compared for their clonal relatedness. Clonal relatedness was compared by randomly amplified polymorphic DNA analysis (RAPD) using three selected primers (GEN 1-60-03, GEN 1-60-06 and GEN 1-60-07). RAPD patterns with DNA fragments ranging from approximately 0.3 to 10.0 kb in size were observed. Examination of the DNA fingerprints using cluster analysis showed a significant genetic diversity among the strains tested.
