Streptococcus pyogenes (Group A) causes “Strep throat” which can alsolead to Scarlett fever and Rheumatic fever in children. Traditional culturemethods provide poor sensitivity for isolating Streptococcus pyogenes. The objective of this study was to validate the use of Colorex™ Strep Aagar (CHROMagar™) to screen for Streptococcus pyogenes on throat swabs set up on the WASP™ using a 30 ul loop and incubated andanalyzed on the WASPLab™ with digital imaging analysis. Streptococcus pyogenes (Group A) grows as orange to red colonies on Colorex™ Strep A agar (CHROMagar™).

Validation and implementation of Colorex™ CHROMagar™Strep A agar on WASP™/WASPLab™ for screening for Streptococcus pyogenes using the ESwab™
