Streptococcal adhesion to immobilized WS and ductal glandular secretions (SMSL, PAR), naturally occurring glycoproteins and related neoglycoproteins. Suspensions of fluorochrome-labeled S. gordonii DL1, capsule-free S. pneumoniae TIGR4 mutant strain HR1001.1, and the respective isogenic SRR adhesin-deficient mutants were overlaid on dot blots of immobilized naturally occurring glycoproteins (Table S1) and related neoglycoproteins (Table S2). Fluorescent signals of bound bacteria were detected by use of a fluorescence scanner.
