November 2021—Hardy Diagnostics released its HardyChrom Group A Strep agar, a chromogenic medium recommended for the selective cultivation and differentiation of group A streptococcus from clinical specimens. Identification can be made based on colony color—the medium will display red-brown or red-orange colonies on the Hardy­Chrom Group A Strep agar when Streptococcus pyogenes is present; non-group A streptococcus isolates will appear as blue, clear, or white colonies.
