SUMMARY: Saliva specimens from 2 groups of volunteers were taken immediately before and after one group had consumed 25,000 i.u. of nisin/day for 14 days, and were analysed quantitatively for total viable and nisin‐resistant bacteria. No significant differences were observed between the pre‐ and post‐test specimens from either group.
