FIG. 6

Adhesion of A. pyogenes strains to epithelial cell lines. A. pyogenes strains were added to cell monolayers and allowed to adhere for 1 h at 37°C prior to washing and recovery of cell-associated bacteria. (A) Adhesion of A. pyogenes BBR1 to CHO, HeLa, and MDBK cells. (B) Adhesion of BBR1 and NANH-1 to HeLa cells. Adhesion is shown as a percentage of the number of bacteria originally added to the cells. Error bars indicate 1 standard deviation from the mean calculated from the averages of at least three independent experiments.
