[Testing of mucosa disinfection methods in the mouth and throat. 1. Effect of chlorhexidine gluconate and PVP-iodine on alpha-hemolytic streptococci].

A method for testing a throat antiseptic procedure is described. As indicator bacteria alpha-hemolytic streptococci were chosen. Povidone-Iodine and Chlorhexidindigluconate (0.5% and 0.1%) and aqua dest. as control substance were tested by a mouthwash technique. The best reduction of alpha-hemolytic streptococci could be detected after mouthwashing by 0.5% Chlorhexidindigluconate (1.4 log reduction), whereas by Povidone-Iodine a reduction of 0.85 log steps was achieved.
