Since the clinical diagnosis of streptococcal infections is necessarily presumptive, epidemiologic studies instituted to detect such infections depend upon the accuracy of laboratory methods used for the isolation of beta-hemolytic streptococci. In this paper the results of comparative studies of various laboratory technics used in culturing and identifying beta-hemolytic streptococci from the throat swabs of Philadelphia school children will be reported. The data were compiled during an epidemiologic study of streptococcal infection conducted since 1955, and described in an accompanying paper.1 These technics vary in some details from those recommended in a statement of the American Heart Association,2 and therefore
