Colony morphology and hemolysis of clinical isolates of <i>A</i>. <i>haemolyticum</i> is enhanced on Todd-Hewitt media supplemented with 6% horse blood.

<p>Growth of clinical isolates for 48 hours in 5% CO₂ showcases the differences between colony morphology and hemolysis of <i>A</i>. <i>haemolyticum</i>. (A) Distinct colony morphologies between smooth (Left-S1) and rough (Right-R44) isolates visualized after 48 h incubation. Line represents 1.0 mm. (B) Hemolysis variation between smooth (Left-S1 and S22) and rough (Right-R49 and R30) isolates.
