Figure Lengend Snippet: Similarities of the 20-bp motif in PCR-amplified reads of 16S rRNA genes among various S. epidermidis isolates. A feature 20-bp motif (orange line) including last 15 bp (blue line) in nucleotides at positions 367–386 was identified from 2,507 S. epidermidis isolates in a rRNA database ( www.arb-silva.de ) (Fig. b). Thirty-one PCR-amplified16S rRNA gene sequences were obtained from various S. epidermidis bacteria, which were not in the rRNA database, were isolated from human scalp (S1-S3), acne lesions (Ac1-Ac5), fingertips (A1-A11), vagina (V1-V6), breast milk (B1-B4) and yogurt (Y1 and Y2). Two 20-bp domains in PCR-amplified reads at nucleotide positions 1–400 and 401–800, respectively, for each S. epidermidis bacterium were identified by Levenshtein distance algorithm (Table ). The similarities (%) between the feature motif and the first 20-bp (including last 15 bp) domains at nucleotide positions 1–400 in 31 S. epidermidis isolates were calculated. The 16S rRNA gene sequence of S. epidermidis (ATCC 12228) was included for comparison. In contrast to S1 and Ac1 (green arrows), S3, Ac3 and Ac4 (red arrows) carried the first 20-bp domains with sequences which were highly similar to those in the 20-bp motif in a reference sequence
