New Research on the Yeast culture effective use has been put to the test, learn more on the subject at http://www.yeast-infection-2.com/ The two-tier defense Protecflor (TM) was demonstrated in an animal model of Traveler's diarrhea (E. coli infection in rats entérotoxigénique). This study showed that after two weeks of administration of probiotic Protecflor (TM) provides better protection in the event of experimental infection with E. coli and S. boulardii alone or the mixture of probiotic bacteria separately. Protecflor reduced weight loss due to infection, stabilize the body temperature of rats and reduces the duration and severity of diarrhea more effectively than bacteria or S. Boulardii.
