Distribution of hemolytic streptococci in respiratory specimens.

Abstract

One hundred thirty-seven isolates of beta-hemolytic streptococci were recovered from 623 pharyngeal cultures. Twenty-nine percent of these were group A, 10% were group B, 31% were group C, 11% were group F, 12% were group G, and 7% could not be grouped. The significance of non-group A isolates in pharyngitis could not be evaluated in the absence of viral and serological studies. Hemolytic streptococci were recovered from 9% of 799 lower respiratory cultures. All except one were non-group A, and other potential respiratory pathogens were also present in these specimens. It is our impression that the presence of hemolytic streptococci in lower respiratory tract specimens usually represents pharnygeal contamination.
