The DNA homology and cell wall sugar constituents of eight Streptococcus sanguis (‐like) strains, three isolated from the patients with Behçet's disease (BD114‐23, BD113‐20, BD118‐1), two from patients with Kawasaki disease (MCLS‐1, MCLS‐2), and three type and reference strains of ATCC (ATCC10556 T : S. sanguis , ATCC10557: S. oralis , and ATCC10558 T : S. gordonii ) were analyzed. Strains BD114‐23 and BD118‐1 showed high DNA homology to ATCC10556 T , and their cell wall constituents were identical. Conversely, BD113‐20, MCLS‐1, MCLS‐2, and ATCC10557 showed little DNA homology to ATCC10556 T and ATCC10558 T , but showed approximately 50 to 60% homology to each other. The cell wall constituents of BD113‐20, MCLS‐1, MCLS‐2, and ATCC10557, however, were somewhat different, indicating that some of the clinical isolates have different characters from those of the three ATCC strains.
