[Laboratory technics for isolation and identification of the streptococci of the microbial flora of the mouth].

It is well known that many streptococcal species are members of the microbial flora of the mouth. We refer to the most important laboratory technics for collecting, transporting and storage, of streptococci, as well as to the manners of isolation, grouping and identification. We describe in detail the two newest of these methods that we use in our laboratory: a) The method "Streptex" by Wellcome Co., England, and b) The method "Api 20 Strep", by Api System S.A. France.
