Abstract: The carrier rate of staphylococcus aureus (S. aureus) in the patients with eczema, the mannitol fermentation test and phagetyping of S. aureus, and the adherence of S. aureus to epidermal cells have been investigated. The results indicated that 1. S. aureus was the predominant organism in the lesion of eczema.2. Most strains of S. aureus in eczema fermented mannitol. In phage-typing, the strains which could be typed were Iower in the eczema vulgaris, and the strains which could be typed were higher in the nvcrobial eczema and those with pyogenic infection. In the distribution of phage groups, there was no statistically significant difference between the strains in eczema and controls (P>0.05). 3. The adherence of S. aureus to the epidermal cells of eczematous lesion was greater than that of normal slap. The relationship between S. nureus and eczema is discussed.
