| Division: | Sciences de la vie | | Catégorie: | Intermédiaire | | Région: | Waterloo-Wellington | | Ville: | Waterloo, ON | | École: | Laurel Heights S.S. | | Sommaire: | The effects of antibacterial toothpaste, containing 0.3% triclosan, on the probiotic lactobacillus (HA-111) bacteria, found in the human gastrointestinal tract, were investigated. Zones of inhibition appeared around filter paper disks inoculated with Colgate Total antibacterial toothpaste that were plated on blood agar plates, swabbed with lactobacillus isolate. Inhibitory zones continued to grow for 24 hours, 12 hours longer than the toothpaste’s claimed effectiveness. |
