Binding of bacterial cells to immobilized Plg. Glu-Plg (20 μg/ml) and BSA (25 μg/ml) were immobilized onto diagnostic glass slides. Enterococcus faecium ATCC 19434, Lactobacillus crispatus ST1 and Staphylococcus aureus NCTC 8325-4 (5 × 10⁸ cells/ml) were allowed to adhere to the immobilized proteins. Adhered bacteria were visualized by staining with Loeffler’s methylene blue. The number of adhered bacteria was quantified microscopically. The mean and the ± SD of adhered bacteria in 19 or 20 randomly chosen microscopic fields in a representative experiment are shown
