Nocardia Species

Colonies are slow growing, aerobic, gram-positive, acid-fast to partially acid-fast, glabrous, heaped and folded, and white, pink, red, orange, or tan in color. Filaments are branched, fragmenting into rod and coccoid forms. Aerial filaments usually present.

Medically important species of Nocardia are lysozyme resistant and do not produce acid from cellobiose.

Handle with care, but special precautions are not necessary.
