Brief Summary

The aim of this study is to evaluate the colonization efficacy of probiotic lozenges and powders containing specific prebiotics in healthy adults

Detailed Description

This is a double-blind, randomized controlled colonization pilot study with no cross over to evaluate the colonization efficacy of lozenges and powders containing two different commercially available probiotic bacteria (S. salivarius K12 ) or S. salivarius M18 with or without 2 different prebiotic sugars or their combinations.

Participants will be randomly assigned to one of the 12 groups consuming probiotic lozenge or powder containing Streptococcus salivarius K12 or S. salivarius M18 with or without prebiotics (e.g. sugars that may promote probiotic activity) over a seven day period. Saliva samples will be collected at predetermined time points pre and post intervention. Colonisation efficacy will be determined by enumerating the probiotic in the saliva samples using standard microbiological techniques.

Primary Outcome Measures

Name	Time	Method
Change in microbial colonization from baseline (Day 0) to 24 hours or S. salivarius K12 lozenges	24 hour	Study will determine the change in microbial colonization efficacy of Streptococcus salivarius K12 with or without prebiotics from a lozenge format. The statistical analysis (e.g. Students t-test) will be carried out to compare the participants data from baseline to 24 hours after later across different formulations with the level of significance of p≤0.05.Overall colonization based on percentage of population colonized for different interventions will also be analyzed average and standard deviation functions using appropriate statistical analysis software (e.g. Microsoft Excel).
