BstEII rRNA gene profiles of nontoxigenic Corynebacterium diphtheriae from isolates submitted to the Public Health Laboratory Service's Streptococcus and Diphtheria Reference Unit from U.K. residents,* 1995. Lanes 1, 4, 7, 10, 13, 16, 19, 22, 25, 28, 31, and 34 contain lambda HindIII digests as size standard (sizes indicated on left). The remaining tracks show ribotypes A to W: lane 2, 95/13 (A); lane 3, 95/281 (B); lane 5, 95/384 (C); lane 6, 95/358 (D); lane 8, 95/220 (E); lane 9, 95/258 (F);
