title: [Simplification of methods for the study of beta hemolytic Streptococcus in faryngeal exudate].
abstract: A procedure of possible epidemiological application is described. The material is taken from pharynx in infants in an attempt to control the serious problem of rheumatic fever in our environment. The investigation is carried out in two steps: in the first, the samples are inoculated in a selective medium impregnated in filter paper strips, from where they are transferred to blood agar plates where 15 to 20 inoculations may be practiced; with this, unnecessary waste of individual plates is avoided, as done following conventional methods. The equipment may be easily adapted for direct takings.
