All specimens were cultured inMitis Salivarius agar medium and the isolated bacterial pure colonies werethenidentified by using VITEK2. Three samples were diagnosed and identified asStaphylococcus lentus. One of the three isolates which showed a distinctive heavygrowth on the media was selected for further analysis in this study. Paper diskdiffusion method was used to detect the antibacterial activityof three of mouthwashsolutions (Zak, Colgate and Listerine).
