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.
