Individual Western blot strips of S. mitis biovar 1, S. oralis, S. mutans, and E. faecalis envelope antigens were incubated with saliva collected from 10 infants (babies 1, 4, 7, 8, 10, 12, 23, 33, 36, and 37) at 1, 6, 12, and 24 months (visits 1, 6, 9, and 12) and probed to detect total SIgA, SIgA1, and SIgA2 antibodies. For each IgA subclass, the percent similarities of the bands recognized by the salivary antibodies both within and among the infants were examined by cluster analysis with Ward’s method (37). Only data for total SIgA antibodies are shown. The data are displayed as dendrograms. (A) Anti-S. mitis biovar 1 total SIgA antibodies; (B) anti-S. oralis total SIgA antibodies; (C) anti-S. mutans total SIgA antibodies; (D) anti-E. faecalis total SIgA antibodies.
