  • Title: Pharmaceutical probiotics for the treatment of anaerobic and other infections.
    Author: McFarland LV, Elmer GW.
    Journal: Anaerobe; 1997; 3(2-3):73-8. PubMed ID: 16887565.
    Abstract:
    Pharmaceutical probiotics have been used as alternative treatments or preventative therapies for a variety of clinical diseases. The overuse of antibiotics and emergence of multiple-antibiotic resistant pathogens has refocused clinical attention on the field of probiotics. Anaerobic infections which seem to respond well to probiotics are infections which involve the disruption of normal microbial flora. Gastrointestinal infections (travelers' diarrhea, antibiotic-associated diarrhea,Clostridium difficile disease, rotavirus diarrhea) have been studied using the following pharmaceutical probiotics:Saccharomyces boulardii, Lactobacillus casei GG, Lactobacillus acidophilus, Lactobacillus bulgaricus, Bifidobacterium bifidum, Streptococcus thermophilus and Enterococcus faecium. Vaginitis has been experimentally studied using L. acidophilus and L. casei GG. The efficacy, safety and mechanisms of action of these various probiotics are reviewed. Requirements for drug approval are similar for biologic probiotics and new drug entities and these requirements involve preclinical tolerability studies, pharmacokinetic studies and large, well-controlled blinded clinical trials.
