Cellulitis is the typical lesion associated with which species?

Cellulitis is a spreading bacterial infection of the skin and subcutaneous tissues, causing redness, warmth, swelling, and pain. The classic organism linked to cellulitis is Streptococcus pyogenes (group A Streptococcus). This bacterium readily invades through minor skin breaks and uses enzymes that help it spread through tissue, leading to the diffuse inflammation seen in cellulitis. While Staphylococcus aureus can also cause cellulitis, exam questions typically point to Streptococcus pyogenes as the characteristic culprit. Mycoplasma lacks a cell wall and doesn’t usually cause cellulitis, and tuberculosis produces granulomatous lesions rather than acute diffuse cellulitis. So the organism most characteristically associated with cellulitis is Streptococcus pyogenes.
