Inhibitory effect of azithromycin on production of bacterial virulence factor and bacterial growth. Experiments were performed in duplicate. Bacterial cells were grown in broth medium with increasing doses of azithromycin for 16 h. Rate of bacterial number density and hemolytic activity to control groups are shown. The data represent the mean and standard error (n = 3). The significance of differences compared with the control group is designated as *p < 0.05 (Williams test, one-sided)
