Staphylococcal skin colonization in children with atopic dermatitis: prevalence, persistence, and transmission of toxigenic and nontoxigenic strains.

Author information

Department of Pediatrics, University of Hamburg, Germany.


Staphylococcal skin colonization is a common feature of atopic dermatitis (AD) in adults. Little is known about prevalence and persistence of staphylococci in children. Forty-one AD children (mean age, 70 months) and 41 age-matched controls were studied. S. aureus was isolated from 38 AD patients (93%; 32% of controls, P less than .001) and 37% of AD patients (5% of controls, P less than .001) harbored toxigenic (enterotoxins, toxic shock syndrome toxin) S. aureus strains. No individual biotype prevailed. On follow-up (mean interval, 9 months), 70% of S. aureus strains were reisolated. Nasal and cutaneous S. aureus strains were identical in 73% of AD patients (7% of controls, P less than .001), reflecting increased self-contamination. Identical staphylococcal strains in AD children and their mothers were observed in 38% (S. aureus) and 16% (coagulase-negative strains; P less than .001). The prevalence of staphylococcal colonization in AD children is comparable to that in adults. High rates of self-contamination, transmission to contacts, and prevalence of toxigenic strains in AD children may have clinical and epidemiologic implications.
