Research output: Contribution to journalArticlepeer-review


An atypical variant of Streptococcus pyogenes was isolated from a discharge from a child's ear. Although this variant streptococcus grew aerobically on chocolate agar, the isolate would not grow on blood agar, the medium used to screen for S. pyogenes, unless it was incubated anaerobically or incubated in air with cocarboxylase.
