["In vitro" study of the bacteriocinogenic capacity of Streptococcus mutans].

In our paper the bacteriocinogen ability of some subspecies of Streptococci mutans has been studied. We have obtained a production percentage of 50%. That production ability was bigger for subspecies mutans than sobrinus in a significative way, who strength the increasing differences between these microorganisms. A brief revision of the role that bacteriocins look like to play in oral ecologist equilibrium and their feasible utilization in dental caries prevention has been done.
