Abstract

Abstract Rapid identification of pathogenic, beta-hemolytic streptococci is important for treatment decisions. We evaluated fluorescence in situ hybridization (FISH) for this purpose using 23 reference strains, 157 clinical isolates, and 80 blood cultures showing streptococci in the Gram stain. With a sensitivity and specificity in excess of 99%, FISH proved to be suitable for rapid identification of beta-hemolytic streptococci in a diagnostic laboratory.
