The capacity of probiotics to ease diarrhoea and other problems associated with antibiotic use in some patients has received fresh backing after a review of studies conducted by University of Toronto researchers. After scrutinising 16 studies involving with 3,403 patients, they found a significant reduction in antibiotic-associated diarrhoea and C.

Background: Probiotic microorganisms are potential treatments for Clostridium difficile diarrheal disease (CDD) but better methods are needed to determine the relative potency of probiotic microorganisms against pathogenic organisms in mixed cultures. Keywords: Probiotic organisms, Clostridium difficile, in vitro testing, qPCR, probotic potency, antibiotic-associated diarrhea, Lactobacillus sp. Increasing attention by both the scientific community and lay public is being directed at the use of probiotic organisms for various indications, some of which are supported by clinical research. Probiotics remain one option for medical treatment or prophylaxis, or possibly as an adjunct to other therapies that have a stronger evidence base [9]. In contrast to antibiotic susceptibility tests with pure cultures, in vitro evaluation of probiotic activity requires some form of co-culture of the probiotic organism (or mixture of probiotic organisms) with a target organisms (or mixture of organisms) that are intended to be controlled by the probiotic. To support this hypothesis, we report here the development of a specific real time PCR method for C. Potential probiotic organisms included two human strains of Lactobacillus which were provided by Dr. Challenge experiments: Lactobacillus overnight cultures were diluted 10, 100 or 1000- fold in fresh MRS broth and 900 Aµl placed in a sterile tube and combined with 100 Aµl of a fresh C.
DNA preparation: At the conclusion of the challenge experiment, a 100 Aµl aliquot from each co-culture was removed, and bacteria were recovered by centrifugation at 12,000 x g followed by a distilled water wash and centrifugation. Statistical evaluation: Most experiments were repeated at least twice and allowing Ct values to be averaged and standard deviations calculated.
The initial goal of this research was to establish the details of a molecular approach to quantitative detection of C. To be a valid method for co-culture experiments, it was necessary to prove that the presence of DNA from microorganisms other than C. The utility of the Toxin A primer set with organisms to be used in this study were adapted for real time quantitative PCR.A  When C. The final validation experiment involved demonstrating the linearity of quantitation of C. The relative probiotic potency of the various Lactobacillus strains available for co-culture experiments was undertaken with proportions of each organism suggested by the initial experiment. The literature portrays CDD as a persistent problem and physicians working primarily in hospitals and nursing facilities are well acquainted with the both the disease and its tendency for recrudescence. The present study was engendered by the recognition that probiotic preparations are variable in their composition and presumably in their relative potency. We hypothesized that molecular methods could be exploited in determining the effect of potential probiotic organisms and we successfully devised a real time quantitative PCR method that enumerated the relative number of C.
A potential limitation of this technique was focusing our measurement of bacteria in mixed culture to C. In terms of the apparent probiotic activity of the organisms tested, it was interesting that the organisms present in the kefir fermented milk product appeared most potent, with a Lactobacillus of human origin almost as potent. In vitro testing of potential probiotic organisms or mixtures of organisms could be helpful in selecting the most potent and most relevant organisms for clinical evaluation of probiotics.
A new molecular technique for measuring relative potency of over-the-counter probiotics was applied to inhibition of Clostridium difficle.

Two potential probiotic strains of Lactobacillus (unspeciated) were kindly provided by Lin Tao, DDS, PhD, College of Dentistry, University of Illinois, Chicago. This study was conducted entirely from internal funding and no extramural support was received.

Probiotics have been suggested as having benefit in decreasing vaginal infections [1, 2] and in regulating the gut flora to decrease the risk of diarrheal disease [3-5]. Over-the-counter products purporting to have probiotic activity enjoy brisk and unregulated sales.
Determining the population dynamics of individual organisms in co-culture is methodologically challenging. After removal of the supernatant fluid 20 Aµl of Lyse-and-GoA® reagent (Pierce, Chicago Ill) was added and the mixture heated according to manufacturers directions to release DNA. Quantitative PCR employed the BioRad Chromo4 instrument and proceeded with a 94 o C melt step for 4 minutes, and then 44 cycles of 94 o C for 20 seconds, 45 o C for 20 seconds, 72 o C for 30 seconds with green fluorescence read at the end of each cycle. 1Electrophoresis of conventional PCR amplification products using Toxin A primer set and genomic target DNA from C. 3Co-culture results of the full panel of probiotic organisms or mixtures of organisms (from kefir) indicated by different symbols, against the full panel of 9 strains of C. In addition, the spectrum of disease has expanded to more community acquired cases [12, 13]. Apparent probiotic potency may be related to the condition being treated, and even when a probiotic organism is identified by genus and species, different strains of the same organism may differ in potency from one to another and there is no a priori means of determining how a probiotic might perform. The kefir inoculum was a mixture of bacteria and yeast, whereas the Lactobacillus A was a single species. In addition, in vitro potency testing could be useful in evaluating products marketed directly to the public, some of which have on occasion proven to have low viability or contain species not listed on the labeling [14].
The technique is able to rank order putative probiotic organisms in terms of inhibitory efficacy against the C.

The mixture was centrifuged and 1 Aµl of the supernatant fluid was used as target DNA for PCR analysis.

Toxin-specific primer sequences were obtained from the literature [11] and are listed in Table 1. In contrast, the same test performed with Lactobacillus DNA showed no amplification product (data not shown). The scope of disease and potential for disastrous outcomes has kindled interest in therapies beyond antibiotic treatments. The significance of this finding resides in our ability to do probiotic experiments without having to perform quantitative culture with difficult to handle anaerobic microorganisms.
The result was an ability to rank the inhibitory potential of the organisms and at the same time to take into account the diversity not only of the probiotic organisms, but the diversity in the relative susceptibility of the C. In addition, it was demonstrated that different clinical isolates of the pathogen of interest displayed varying degrees of susceptibility to a panel of potential probiotics.
However, we did control the quantity of the Lactobacillus or other probiotic mixtures through dilution and this technique was sufficient to indicate the necessity of numerical dominance of the probiotic organism. The biological activity of probiotic candidate organisms or mixtures of organisms has required challenging laboratory techniques such as embedding pathogens in agar-based growth medium and placing potential probiotics on the medium to look for zones of inhibition.
Probiotics and functional foods have been used as one approach to prevention or treatment of symptoms but reviews have indicated a beneficial effect [6] or lack of significant beneficial effect of the probiotic approach [7]. Ct is the number of PCR cycles needed to obtain a detectable fluorescent signal above background. Among the alternative therapies that have received significant attention is use of probiotic microorganisms, functional foods containing probiotic organisms or prebiotics which support colonization by a favorable flora. This finding should emphasize that in clinical studies, efficacy of a probiotic should take into account the dose of the probiotic and whether it is viable or not, and whether it survives in the host.
Mixed cultures are attractive as they put probiotics and pathogens in immediate contact without inhibitory mediators having to diffuse through semi-solid media, but identifying one organism in the presence of another in such mixed-culture experiments can prove technically challenging. Inconsistency among observed clinical effects of probiotics may be in part related to the variation in actual probiotic preparations.
PCR was carried out according to the following program: 4 min 95 o C, followed by 35 cycles of 95 o C for 30 seconds, 48 o C for 30 seconds (for Toxin A) or 45o C (for Toxin B), 72 o C for 1 minute with a final 4 min extension step at 72 o C.
Well-controlled clinical studies are limited and have failed to provide support for the probiotic approach to CDD [7] but interest in probiotic treatments remains and further clinical studies can be anticipated, especially in parts of the world where medical resources are limiting factors. The qPCR method employed here could, with the addition of reactions to quantitate the probiotic organisms, show the relative abundance of all players in the mixed cultures evaluated. These issues were overcome in the present study by the use of a molecular approach based on specific quantitative PCR of the C. Serial dilutions of Lactobacillus cultures or microbial mixtures from kefir were co-cultured with C. The importance of this finding is in its ability to help in the prediction of which probiotic organisms or combination might be best for selection in future clinical trials. Results: Strains of Lactobacillus (human and ATCC derived), and mixed cultures from commercial kefir were co-cultured with C. Lactobacillus and the microbial mixture from kefir were ranked in order of their potency in C.
The technique measures relative potency of over-the-counter probiotics and may predict human strains meriting probiotic status.
