FIG. 4.

Effect of actin binding compounds on BMK cells. BMK cells were pretreated with media alone or media containing either lat A (black bars), cyto B (white bars), or jas (dotted bars). Cells were infected with Py (at an MOI of 10) for 1 h in media alone or media containing the above compounds. The compounds were washed out, and neutralizing antibody was added at the indicated time points. Cells were examined for Py LTAg staining at 24 h. Approximately 500 nuclei were counted per sample, and the data are presented as described in the legend to Fig. 1.
