A Selective Medium for the Isolation of Streptococcus salivarius.

Conclusions

A medium has been developed on which a specific oral streptococcus can be selectively isolated from mixed bacterial populations. The value of this selective medium as a detector of oral contamination of restaurant eating utensils is indicated by the distribution studies, which show that this bacterium is found normally in the human mouth and on articles which have come in direct contact with human lips.
