We examined 52 patients with infantile seborrhoeic dermatitis (ISD) and 47 healthy 1-month-old infants. Yeast cells on the right side of the face were counted by direct microscopic examination, and isolates from the left side of the face were identified by Tween test. Yeast cells were more numerous patients with ISD than in the healthy infants. M. furfur and M. globosa were isolated from ISD patients at significantly higher rates than from healthy infants.
