title: [Simple and rapid technic of grouping of streptococci].
abstract: The authors propose a simple and rapid technique of grouping of streptococci. Streptococcal extracts were obtained by the action of nitrous acid at laboratory temperature. Serogrouping was carried out by electro-immunodiffusion. A study was made of 200 strains of hospital origin. The qualities of specificity and sensitivity of the method proposed are emphasized.
