3 PROBIOTICS “ Live microorganisms which when administered in adequate amounts confer a health benefit on the host” Probiotic microorganisms can be found in both supplement form and as components of foods and beverages.

Private & Confidential 4 TYPES OF PROBIOTIC Lactobacillus - Most available are species are, - L.acidophilus - L.casei - L.reuterii - L.rhamnosus - L.bulgaricus - L.plantarum Bifidobacteria - Most available are species are, - B.infantis - B.longum - B.bifidum - B.lactis Saccharomyces boulardii – Widely studied probiotic yeast Saccharomyces cerevisiae- Most used probiotic strain for varied applications

S. boulardii Is Effective in Patients with Recurrent C. difficile Disease CDD=Clostridium difficile-associated disease McFarland L, et al. JAMA. 1994;271: Initial CDD CDD recurrence, % S. boulardii (n=31) Placebo (n=33 ) P=NS Recurrent CDD Control (n=34) P=0.04 Patients received standard antibiotics (vancomycin or metronidazole) and S. boulardii 1 g/day or placebo for 4 weeks. CDD recurrence, % S. boulardii (n=26)

Mixtures included: Lactinex = L. acidophilus and L. bulgaricus; Lactobacillus acidophilus and Bifidobacterium lactis; Lactobacillus acidophilus and Bifidobacterium infantis. McFarland, Am J Gastroenterol 2006; 101(4): PROBIOTICS FOR PREVENTION OF ANTIBIOTIC ASSOCIATED DIARRHEA

 Probiotics are live active cultures  More is not better  Dose (1 billion vs 10 billion vs 450 billion)  Number of strains  The effect of probiotics is genus specific MISCONCEPTIONS ABOUT PROBIOTICS

DOSAGE & STRAINS OF PROBIOTICS 10 The dose of probiotics is usually expressed as the number of colony forming units (CFUs) The required dose of probiotics may vary greatly for different strains and the specific health effect under investigation Probiotic effects should be considered dose-specific Dose listed on the label must be based on studies that show a health effect in humans Different strains of the same species can be different Clinical support to substantiate claims must be for each probiotic strain
